I n these economic times, it is more important than ever that we be able to provide a wider

range of services to our patients. In that effort we are focusing for the AES to be more

important to practicing dentists. Please take the opportunity to unlock your information so

that patients can access it from the AES website.

The book SWAY -The Irresistible Pull Of Irrational Behavior by Ori and Rom Brafman describes

the phenomenon of “sway” as being when a person lets his past history determine his future

actions. Think about a dentist who really cares about you and has done the root canal, the post

& core, the crown and then recommends an apico surgery, not because it is the best treatment

but because he is vested in that tooth. Similarly, we must resist the “sway” in diagnosing and

treating our patients. In these difficult economic conditions we must resist looking at our

patients as economic opportunities and remember they are people in need. A patient suffering

from TMD who is in pain may just need a splint and time to heal, not a full mouth reconstruction.

While it has been said that ignorance is bliss, as a dentist it can also be expensive. Malcolm

Gladwell, author of The Tipping Point and keynote speaker at the 2006 Dental Trade Alliance

meeting mentions our dental industry is fragmented and could benefit from “a trusted voice” to

sort through and make sense of the overwhelming deluge of available technology and dental

services (LMT Comm, Oct 2006). Dental technology has reached a tipping point where you can

buy more technology than you can make a profit with. It is the mission of AES to enrich the lives

of our members, the dental community and the public we serve through education, mentorship

and research.

It is still true today that you only see what you know. For the 2012 AES Scientific and Clinical

Sessions, our Program Chairmen Dr. Matt Lark and Dr. Jeffrey Okeson have organized a group of

outstanding speakers with significant clinical information to share, enlighten and challenge us to

better treat the needs of our patients. I hope you plan on joining us!

Letter from the Editor

Tara Griffin, DMD,FAGD

T his year’s AES Annual Meeting was one to remember. Program co-chairmen Bo Bruce and

Dave Newkirk assembled an outstanding group of clinicians who provided invaluable

information to those in attendance. This meeting was also memorable because it was

dedicated to Dr. Pete Dawson. Past President Witt Wilkerson presented Dr. Dawson with a plaque from

AES that had a picture of Pete with his wife Jodi who is wearing a hat that says Life is good. Almost

every one of us has heard that slogan or seen a hat or T-shirt with a smiling face and the Life is goodwords printed on it. The message is so simple, yet powerful, and I was curious to find out how such a

simple message had become so popular.

I found a recent story in the Experience Life magazine (March 2011) about the development of the

Life is good brand that I would like to share. I believe it exemplifies what all of strive us to achieve in our

life and what a perfect slogan and message that is for Dr. Dawson and his family to share with each

other and with us.

The two youngest of six children from Massachusetts, Bert and John Jacobs learned about the

power of positive thinking from their mother, who always looked on the bright side of things even

when money was tight. The brothers’ ultimate dream was to share that hopeful message with the

world through art. Neither brother knew anything about starting a business. They chose to sell T-

shirts because it was a simple, cheap way to get an immediate reaction from people. After five years

of selling their self-designed T-shirts at weekend street fairs and college dorms, the brothers were

broke. So they each took jobs as substitute teachers and agreed to give T-shirts just one last shot.

They printed 48 shirts with a new design: a simple smiling face and the slogan, Life is good. Jake,

the cartoon hero of the Life is good brand was created by John Jacobs. At a street fair in

Cambridge, Mass., in 1994, they sold out in 45 minutes. Today, their company, Life is good, is a

$100 million business. Jacobs believes the T-shirts are popular with consumers because of the

optimistic message. He believes our culture is so overwhelmed with negativity and that the focus

should be on what's right with the world, rather than on what's wrong. Hence their mission: to

spread the power of hope and a healthy optimistic strategy for living.

The company also focuses on giving back, which is a core part of the company’s mission. The Life isgood Kids Foundation helps children overcome life-threatening challenges, such as violence, illness and

extreme poverty. The Jacobs receive countless letters and photos from a wide fan base. Dear to their

hearts are the letters from people who say that they wore their Life is good shirts or hats to get through

difficult times. The Jacobs brothers believe these are the people who have taught us the true

meaning of their message. They say, “We all have a choice. We can focus on what's wrong

with the world, or we can see the sunny side, even when it rains.” One of their favorite

sayings is, 'Remember that the music is not in the guitar.’ According to the brothers, “We

get to decide how to use what we have and that's the great thing about optimism. You

don't start it or own it. You simply let it loose in the world and help it grow."

Thank you to Dr. Dawson and all of those who have contributed so much to our

profession. Thank you for your optimism and allowing us to grow and follow in your

footsteps. And, thank you to all who attended this year’s meeting. We have another

phenomenal program organized by co-chairmen Matt Lark and Jeff Okeson for the

2012 Annual Meeting. I encourage you to look ahead and plan to attend! And,

remember Life is good!

RESERVE THE DATE57th Annual Scientific Meeting

February 22-23, 2012Chicago Marriott Hotel • Chicago, Illinois

Evidenced Based TMD: Paradigms for a New DecadeProgram Co�chairmen: Dr. Matthew Lark and Dr. Jeffrey Okeson


10 AES Contact

A t the AES 56th annual meeting, Dr. John Grippo began

his lecture on abfractions with the statement, “Every

engineer knows that when a fly lands on a bridge,

there is a corresponding deflection.” He was talking about

Newton’s (Sir Isaac Newton, 1642-1727) Third Law which is that

action and reaction are equal and

opposite, and that all the forces acting

within a system must balance out. If a

weight presses down on the floor, the

floor must press up on the weight with an

equal and opposite force.

But it was the British physicist Robert

Hooke (1635-1703) who approached the

study of the effects of forces on different

materials by measuring the resulting

deflections from that force. He

discovered that when the load was

progressively removed, the specimens

returned to their original length. Hooke

was saying that a solid material can resist

an applied force only by yielding to it, ie;

by contracting under a compressive load

or by stretching under a tensile

one. His work was the logical

consequence of Newton’s

Third Law.

Hooke and Newton’s ideas

were not confined to artificial

materials, but biological as

well. This gave birth to the new

science of biomechanics,

which is the study of the

mechanical behavior of living

material and structures. So it is important that we examine

subjects of significance in biology such as the human dentition

with a fresh point of view which brings us to Deformations in the

Oral Environment Due to Dental Compression Syndrome.

Dental Compression Syndrome (DCS) is a contemporary term

for the age old condition of grinding

and/or clenching of one’s teeth. One

reason DCS has been so successful over

the centuries is that it works well within

one’s subconscious. Since few patients

affected by DCS are aware, dentists

must recognize the visual signs of

compression in order to address the

problem. Besides the obvious signs of a

flattened dentition and hypertrophied

muscles of mastication, there are certain

deformations caused by compression

that many dentists misdiagnose or don’t

understand. Nevertheless, these

deformations affect dentition, bone, and

restorative materials.

Deformations of theDentition Classified as non-carious

lesions (NCLs), these defects

typically are site-specific, in

that they appear at the tips of

functional cusps and the

gingival area of teeth where

susceptibility to stress is high

(Figs. 1 and 2) A finite element

analysis of a tooth model

AES Contact 11

confirms that stress is

highest in these areas

(Fig 3).

There are two distinct

mechanisms responsible

for the loss of tooth

structure during

compression: tensile

forces and positive ion

egress . Engineers tell us

that these high stresses

may be responsible for

the pain experienced by

patients who have

restorations in the

gingival area where

tensile forces are

powerful enough to pull

apart the enamel prisms.

Although NCLs can

be caused by a variety

of agents, such as low

pH and mechanical abrasion, compression NCLs are

distinguished by a glassy sheen. Kornfeld wrote about this

phenomenon in 1932, when he observed that these defects

were hard, smooth, and almost glasslike in appearance . This

glassy effect may be due to the exit of positive ions from

these focal points of high stress . The ions are produced by

the compression of apatite crystals in the dentition and

alveolar bone—the piezoelectric effect.

It is to be noted that compression NCLs do not appear on all

patients who clench their teeth, not only because of variations

in the intensity and frequency of DCS, but primarily because of

genetics. NCLs seem to be more prevalent and dramatic in

patients with dense alveolar bone than in patients with

periodontally compromised teeth. Compression NCLs have

been the subject of controversy among dentists for decades.

W. I. Ferrier once wrote that “their etiology seems to be

shrouded in mystery.” But NCLs are not such a mystery if we

understand the science of biomechanics. Subject to distracting

labels such as “McCoy’s notches” and “abfractions,” these

defects require a more scientific identification, which is

essential to understanding their significance. What we are

actually seeing are multi-shaped examples of hard tissue

fatigue (Figs. 4–9 due to compression failure).

Fatigue applies to changes in the properties of a material

due to repeated applications of stress or strain—in this case,

compression failure from DCS. J. E. Gordon, a professor of

materials at Reading University, describes fatigue as “one of

the most insidious causes of loss of strength in a structure.” If

an object, such as a tennis ball, rebounds to its original shape

after repeated compression, it is said to be elastic in nature.

However, if an object exhibits residual defects after repeated

compression, it is said to be plastic in nature. Biological

structures, such as teeth and bone, are termed viscoelastic.

Compression fatigue also occurs in the spine (Fig. 10). In

orthopedics, these sites of destructive stress are termed

compression or wedge fractures.

The compression failure of an object occurs at its most

vulnerable site. Teeth are most susceptible at the gingival area

(Fig. 11).

If alveolar bone recedes, the failure site will also be lowered.

Figs. 12 and 13 demonstrate defects that appear in tandem as

the supporting bone atrophies, thus changing the fulcrum point.

Also note in Fig. 12 that the only occlusal contact is on the

incline plane, forcing the bicuspid to be flexed toward the

lingual when the patient clenches.

Deformations of Restorative MaterialsFatigue easily manifests itself in prostheses and restorative

materials such as amalgam and acrylic. In engineering, these

wavy patterns are called “Luder Lines,” or molecular slipbands.

The explanation for the patterns is that molecules in the alloy

are rearranging themselves under the influence of compressive

strain. One can demonstrate the effect by bending a metal coat

hanger back and forth and examining the stress configuration

that is produced. Figs. 14–17 demonstrate Luder Lines in

restorative materials.

Deformations of Bone (Exostosis)Articles on torus palatinus and torus mandibularis have

appeared since 1814 (Figs. 18–21). Although there is not a

consensus on their etiology, many associate their

occurrence with TMDs and masticatory hyperfunction.

The author has long suggested that the compression of

hydroxlapatire in the dentition and bone generates

negative ions that result in exostosis (the piezoelectric

effect). A situation such as this may well explain the

metallic taste that people experience from time to time.

EpidemiologyA survey was taken of 100 patients (50 female; 50 male;

age range, 17–76) to determine how many exhibited

signs and symptoms of DCS and TMD (see Table).

SummaryWhy is the recognition and understanding of

these deformations important? During the forty

three years I have been in general practice, I

have not seen one case of temporomandibular

disorder or oral facial pain where the patient did

not exhibit at least one or more signs of DCS.

Treatment for DCS begins with the

recognition that these deformations are

important diagnostic tools, and proceeds with a

simple three step management regimen of

education, equilibration, and guard therapy in

order to reduce the intensity of the compression.

R ecently the American Equilibration Society Scientific

Investigation Committee completed its first

review of the dental literature dealing with

occlusion. The review of such a large topic generates a

very wide variety of literature, dealing with the many

aspects of occlusion and its significance in various

dental therapies. I wanted to expand on one point that

was considered in the search, and perhaps provide

some information that will be of value to every AES

member as they read articles of interest to them.

As we all know, there has been a dramatic increase

in the volume of dental literature over the past two

decades. Evidenced based dentistry has emerged as

an important factor in aiding the practitioner in

determining the proper therapy for the patient in all

areas of treatment. The practitioner at times is deluged

with a wide a variety and number of literature articles to

review to stay abreast of the latest recommendations in

our profession.

One graphic and system used in our recent review

was a “Grading Levels of Evidence” developed and

utilized by Dr. Derek Richards, Director, Centre for

Evidence-based Dentistry, Oxford UK., and editor of

the Evidenced-Based Dentistry Journal. The system

can be used to identify varying levels of evidence used in a

given article. We are all familiar with the basic design of

research or investigative projects. As a committee, we

attempted to complete our review of the occlusion literature

and give AES an idea of just where much of the literature fell.

While there is much discussion recently of high level, low level

and mid level research, confusion can remain for the

practitioner when decision making is required. In most of the

articles we read as practitioners, levels of evidence can be

determined. The levels utilized by Dr. Richards are as follows:

1A Systematic Review (with homogeneity) of Randomized

Controlled Trials

1B Individual Randomized Controlled Trials (with narrow

Confidence Interval)

2A Systematic Review (with homogeneity) of Cohort Studies

2B Individual Cohort Study (including low level RCT, e.g. < 80%

follow-up

2C Ecological Studies

3A Systematic Review (with homogeneity) of Case Control Studies

A few definitions may be helpful in aiding the reader. These

definitions were provided to the AES Clinical Practice

Guidelines Committee during a lecture by Dr. Richard

Niederman in March 2006. Dr. Niederman is Director of the

DSM-Forsyth Center for Evidence Based Dentistry.

Systematic Review (SR): A review of a clearly formulated question that uses systematic

and explicit methods to identify, select, and critically appraise

relevant research and to collect and analyze data from studies

that are included in the review. Statistical methods (meta-

analysis) may or may not be used to analyses and summarize

the results of the included studies.

Randomized Controlled Trial: An experiment in which two or more interventions, possible

including a control intervention or no intervention, are

compared by being randomly allocated to participants. In most

trials one intervention is assigned

to each individual but sometimes

assignment is to define groups of

individuals (for example, in a

household) or interventions are

assigned within individuals (for

example, in different orders or to

different parts of the body).

Homogeneity: 1. Used in a general sense to describe the variation in or

diversity of participants interventions and measurement of

outcomes across a set of studies, or the variation in internal

validity of those studies.

2. Used specifically, as statistical heterogeneity, to describe the

degree of variation in the effect estimates from a set of

studies. Also used to indicate the presence of variability

among studies beyond the amount expected due solely to

the play of chance.

Confidence Interval (CI): Quantifies the uncertainty in measurement. It is usually

reported as a 96% CI which is the range of values within

which we can be 95% sure that the true value for the whole

population lies.

Cohort study: An observational study in which a defined group of people (the

cohort) is followed over time. The outcomes of people in subsets

of this cohort are compared to examine people who are exposed

or not exposed to particular intervention or other factor of

interest. A prospective cohort study assembles participants and

follows them into the future. A retrospective study (or historical)

cohort study identifies subjects from past records and follows

them from the time of those records to the present. Because

subjects are not allocated by the investigator to different

interventions or other exposures, adjusted analysis is usually

required to minimize the influence of other factors (confounders).

Case control series: A study that compares people with specific disease or outcome

of interest (cases) to people from the same population without

that disease or outcome (controls), and which seeks to find

associations between the outcome and prior exposure to

particular factors. This design is particularly useful where the

outcome is rare and past exposure can be reliably measured.

Case control studies are usually retrospective, but not always.

Case study:A study reporting observations on a single individual. Also

called anecdote, case history, or single case report.

When reading articles, one can usually determine the level of

evidence from the abstract. There are instances where the

entire article must be read to determine the level of evidence,

and one may find that a given article is written in a such a way

that it is very difficult, if not impossible, to determine just where

the articles falls in this level of evidence model.

There has been considerable discussion between well

meaning persons in our profession regarding the use of high level

evidence in decision making. One should remember that not all

“Not all research projects can be constructedin such a way as to meet the highest level ofevidence based dentistry.”

research can be subjected to certain evidence protocols. As Dr.

Terry Donovan commented in his recent presentation at the AES

2011 annual meeting, “Not all research projects can be

constructed in such a way as to meet the highest level of

evidence based dentistry.” That should not mean that we reject

conclusions from lower level research. We must realize at times

that what we are reading may be the best evidence we have to

aid us in our clinical decision making. While high evidence may be

lacking, we as clinicians must employe the best levels available to

us at the moment. Often there are comments in articles dealing

with dental occlusion that state there is no “evidence” to support

occlusal therapy. In reality there may be lower level articles, and

these may just be the best we have to choose from in our

decision making process. There is a need for increased levels of

evidence in much of the dental literature, including the field of

occlusion, however, it will take time to fulfill this need.

In completing this year’s review of the dental literature, we

found that the articles reviewed could be categorized in the

following categories.

1A Systematic Review 0%

1B Individual RCT 6%

2A Systematic Review of Cohort Studies 0%

2B Individual cohort Studies 31%

2C Ecological Studies 1%

3A Systematic Review of Case Control Studies 4%

3B Individual case control studies 48%

4 Case-series 0%

5 Expert opinion 5%

I would encourage everyone to try applying the levels of

evidence to their professional readings. It may seem cumbersome

at first; however, as one utilizes the process more frequently it

does become easier. The benefits of using it may be improved

understanding of the dental literature, research methodology, and

added help in our daily clinical decision making process. Long

term, our patients will be the beneficiaries.

I n 1979, when unrest in the Middle East caused volatile fuel

prices to escalate rapidly, American Airlines CEO Al Casey

asked a consulting firm for options. The firm responded

that the airline had 3 options when the transport cost per air-mile

exceeded the ticket revenue:

1. The airline could continue its current pricing structure and

hope that oil prices would fall.

2. The airline could embark on a strategy to sell 10 -15% more

tickets than available seats and hope that passenger no-

show rates would maintain profit margins.

3. The airline could adopt a new business model to maximize seat

occupancy and incorporate a new pricing strategy that avoided

large losses when costs escalated beyond ticket prices.

In 2011 the AES is facing the same issue of costs

exceeding revenues and will be asking membership to

consider available options.

As you know, the AES has a pricing structure that combines

membership and meeting registration in one annual

membership fee. Over the last 13 years, we have only raised

our fees $100, even though meeting costs have risen

paralleling a 35% CPI increase for that time span. In 2011,

after a very successful and well attended meeting, the AES

lost $44,000 when meeting costs exceeded revenues.

The AES Board convened a Business Model Ad Hoc

Committee to evaluate all options for our society. After a

thorough evaluation of membership trends, meeting

attendance, meeting costs, and business structures of similar

organizations, the ad hoc came to the following conclusions:

1. We lose money with good meetings. Excellent meetings

with a high percentage of member attendance actually

cause greater losses. Because meeting registration is rolled

into an annual membership fee, our more profitable years

have been ones when fewer members attend our scientific

session; hence the cost of the meeting decreases while our

revenues stay the same.

2. Similar organizations have been more proactive inadjusting their business structure to avoid losses. Five

comparable organizations were evaluated (AAOP, IACA,

AACP, AHS, and AAFP). All have higher annual fees, ranging

from 9% to 154% higher than AES. Most have a base

membership fee to cover member benefits and services

and a separate meeting registration fee to amortize the

meeting costs over those that attend the meeting. Most

have adjusted their fees more frequently than AES.

3. We need to actively survey and communicate with ourmembership. We have a tremendously talented and

insightful membership and we need to more proactively

educate you and ask your opinion.

Expect an important survey about business structurewithin the next month. Please read the information carefullyand respond. Your opinions are important and will bethoroughly considered!

With your help, we will continue to make AES the pre-eminent

organization devoted to the pursuit of knowledge about form,

function, and pathology of the masticatory system.

Dr. Barry Glassman presented the topic of chronic painmanagement. He posed the question, “How doesocclusion matter and why?” The complexity of analtered central nervous system, central sensitizationsyndrome (CSS), and chronic regional pain wasdiscussed. Possible treatment options proposedincluded decreasing trigeminal nociceptive afferentsignals and reducing nocturnal and diurnalparafunctional forces.

The definition of chronic pain is pain that persistspast the healing phase following an injury. Neuropathicand inflammatory injuries that cause a persistent paincondition suggest that peripheral and spinal cordcircuitry transmitting nociceptive signals undergodramatic reorganization that involve plastic changes.Chronic orofacial pain can be divided into three states:musculoskeletal, neurovascular and neuropathic.

Musculoskeletal pain is found under the “umbrella”term Temporomandibular Disorder (TMD). The termTMD is of limited value, as it classifies articularproblems with muscle disorders that have differentetiologies and treatment approaches.

The neurobiological mechanism of pain involves theperipheral afferent sensitization, central sensitization andimbalance of descending inhibitory systems. Occlusion,hyper-muscle activity and the chronic pain model are avicious cycle. The pain adaptation model replaces thevicious cycle model, as it eliminates trigger points andmuscle spasms. The introduction of an occlusalinterference does not necessarily cause chronic pain.

The complexity of the sympathetic nervous systemmust be understood to be able to interpret pain. CSShas a normal “signal” with an altered interpretation andresponse. The underlying etiological factors can be painsensitivity or altered central pain regulatory mechanisms.The evidence suggests that other common painconditions do not exhibit signs of resting or posturalmuscle hyperactivity. Awake muscle activity in a chronicpain patient is different than that of nocturnal muscleactivity. There is no difference between the restingmuscle activity levels in subjects who report pain andthose who do not in bruxers. It is important to understandthe concept of “non-linear” relationships betweenbruxism and craniofacial pain to avoid oversimplificationof diagnosis and management. Therefore, the rationale oftreatment that is aimed at pain relief through thereduction of muscle hyperactivity is unsupported.

The term TMD was confusing when it was used as adiagnosis, and the diagnosis of TMD itself is a barrier.For neurovascular and neuropathic orofacial pain, thediagnosis may not have a dental cause and theocclusal scheme may not be the best diagnosticperimeter for determination of etiology.

“Factors of Functional Occlusion”Abstract: Dr. Catherine Kwon


The question of where to start in the treatment of apatient with an envelope of function problem can be

difficult to answer. A simple method is to determine ifthe occlusal plane is ideal. The mandibular anteriors area good starting point if the occlusal plane isacceptable. If the occlusal plane is non-ideal, themaxillary centrals are the recommended starting point.When natural function is developed, natural estheticswill follow. The correct proportion of the anterior teethfollowed by the correct incisal position in the verticaland horizontal plane will produce the correct form andfunction that is desired. The form of the anterior teethleads to their ideal function. The facial gingival thirdprovides support for the upper lip while the incisal thirdsupports the lower lip. The lingual incisal half aids inthe production of the sibilants (“s”) while the lingualincisal third produces the linguodental sounds (“th”).The cingulum provides a stable centric stop. Followingthese simple guidelines will help answer the difficultquestions that arise when treating a patient with anenvelope of function problem.

“Factors of Functional Esthetic Success”

Abstract: Dr. Catherine KwonGraduate Student, Advanced Education Program in

Prosthodontics, Loma Linda University School of Dentistry

Applying simple principles to blend the functional andesthetic disciplines will lead to results that are healthy,predictable, beautiful, and stable. The functionparameters that are evaluated are (1) thetemporomandibular joints, (2) the posterior teeth and (3)the anterior teeth. First, the temporomandibular jointsmust be fully seated. Then the posterior teeth areobserved in excursive movements to ensure thatinterferences are not present. Lastly, the anteriorguidance is observed to be in harmony with theposterior teeth. The result will be the precise harmonyof the lateral pterygoid muscles. The estheticparameters that are critical are (1) facial analysis, (2)anterior smile and (3) posterior smile. The facialanalysis will provide information regarding the skeletalprofile and the lip dynamics in a full smile and the “E”position. The anterior smile wil l determine thehorizontal and vertical position of the maxillary central

incisors. The posterior smile will reveal the amount ofbuccal corridor that is visible. These parameters areevaluated with the provisionals to test the esthetics,function, and phonetics. These three parameters willlead to functional stability of the occlusion.

“Occlusion for Dental Implants: The Critical Factor in Implant Success”

Abstract: Dr. Alfredo Paredes Graduate Student, Advanced Education Program in


How important is occlusion? Occlusion may be the mostcritical factor for implant success. There are different typesof occlusal schemes used in complete dentures andimplant restorations, e.g., anterior guidance or mutuallyprotected occlusion, group function and bilateralbalanced occlusion. Bilateral balanced occlusion isnecessary in complete denture stability, better tissueresponse and uniform inflammation. Balanced articulationbecomes important in parafunction, which is a protectivemechanism for the patient. Anterior guidance or mutuallyprotective occlusion involving excursive and protrusivemovements in a clinical scenario would be defined asparafunction. D’Amico described mutually protectedocclusion as the guidance of closure of the mandiblebetween the last millimeter and maximal intercuspalposition, which is ideally carried out by the canines.

Functional occlusion demands an understanding ofthe masticatory cycle in a 3-dimensionalrepresentation, which directly impacts the loading ofnatural dentition and dental implants. When restoringdentition with dental implants, during bruxism andparafunction, allow natural teeth to control guidanceand the implants to support centric stops. In addition,the natural dentition are inclined facially. In the samemanner, the implant should have the same position andangulation as natural teeth, which will create thecompensating curves of Spee and Wilson to achieve anoptimal position of the dental implant.

In conclusion, the masticatory cycle is the mostfunctional load placed on dental implants. Therefore, themost important consideration when designing an implantrestoration is the masticatory cycle.

“Occlusal Equilibration – How It’s Taught”

Abstract: Dr. Wendy GregoriusGraduate Student, Advanced Education Program in


Dr. John Kois discussed a patient case, in which thepatient presented with headaches, muscle fatigue anda night guard that had been used with limited success.The patient had orthodontic treatment twice and wasnow suffering from bite problems. An occlusal stresstest was performed for finding the threshold level atwhich symptoms occur. The diagnosis was occlusaldysfunction or disease of maximal intercuspal position.

This procedure was made in five deliberateappointments and the equilibration should take aboutone hour. Laboratory fabrication of a deprogrammer forsuppression of ingrams, to read the biology of thepatient by checking for absence of symptoms, and forcontrolling the centric relation was done. Thedeprogrammer was placed in the mouth and verificationof 1.0 mm to 1.5 mm separation of the molar region wasmade. The back of the deprogrammer platform acrylicwas reduced and flattened. A bite record was made atan open vertical position. The initial point of contact wasfound as the teeth were engaged and the patient waschecked for absence of symptoms. The first point ofcontact was reduced keeping it level and horizontalusing Bausch 200 Microns Articulating Paper. The teethwere verified for contact on both sides. AccuFilm®(20m) was used to find the second point of contact.This point was verified on the mounted casts in the labfor the trial equilibration, which served as the guide forthe clinical equilibration.

The patient returned for the equil ibrationappointment, during which only inclines and fossaswere reduced. Cusp tips were not flattened, but onlythe fossas were deepened for the purpose of notreducing the memory concerns of the patient. Whenthe patient was able to point to the tooth that was now

Dr. Glenn E.

The six steps to accomplish an equilibrationpredictably and efficiently are: (1) perform a thoroughevaluation of the temporomandibular joints, musclesand supporting tissues, (2) perform a trial equilibrationon accurately mounted study casts, (3) providedefinitive contacts on all teeth of equal intensity incentric relation, (4) eliminate posterior interferences inall excursions, (5) refine the anterior guidance, and (6)recheck and provide final check of each criteria.Proper equilibration never harms the patient, never

restricts movements, never mutilates teeth and createscomfort and stability.

“Occlusal Equilibration – How It’s Taught”



Dr. Clayton A. Chan presented a discussion onocclusal equil ibration in relationship to theneuromuscular concept. Occlusion is the foundation toadvanced dentistry. Establishing a physiologic terminalcontact position first is one of the paramount aspectsthat is taught. Occlusion affects the whole body,central nervous system, autonomic nervous system,teeth, muscles and temporomandibular joints (TMJ).Occlusal equilibration should support stabilization ofthe periodontium and dental occlusion, reduction inTMJ clicks and pops, elimination of masticatorymuscles pain and dysfunction, removal of abnormaljaw closure patterns, improved maxillary to mandibularposture and stability, and improving head, cervicalspine, occiput and pelvis balance. Conservativereversible treatment is paramount by stabilization ofthe masticatory system using a removable anatomicalorthotic appliance after identification of a physiologicoptimal bite f irst. There are three stages ofgneuromuscular occlusion: (1) establish myocentricfirst, (2) establish physiologic mandibular function, and(3) refine anatomical form of the incline planes.Myocentric is established with the aid of low frequencyTENS. Prior to reconstruction, homeostasis isestablished. Phase I includes orthopedic stabilization.Torques are identified. Jaw tracking combined withtranscutaneous electrical nerve stimulation (TENS) isused for finding a proper anterior overjet and overlapfor proper cranial stabilization during functioningmode. Cuspid rise is incorporated into the orthoticappliance. Computerized mandibular scanning is usedto measure mandibular positioning, quality of terminalcontact and jaw closing patterns. A chew test scan isused to observe dynamic chewing patterns. Thepatient is restored with optimal occlusion.

“How Computer-Guided Occlusion is Taught”Abstract: Dr. Wendy Gregorius


Dr. Robert B. Kerstein presented how computer-guided occlusion is taught using the T-Scan. Studentstake a two-day interactive training seminar to learn,record and understand digital data, timing and force-mapping. They then treat patients by applying thedigital data. The two-day training seminar objectivesare to obtain better occlusal data with computerizedocclusal analysis, analyze the time-sequencing andforce-mapping recorded data, improve clinician’svisibility of occlusal problems, translate articulatingpaper marks with digital occlusion, improve patientoutcomes and enhance education and caseacceptance. Training involves proper recordingtechniques. The digital occlusion clinician learns howto record the timing of intercuspation contactssequence, posterior disclusion sequence, sequenceof delayed implant prosthesis contact, and the force-mapping of each occlusal contact in sequence. Thistiming and force data illustrates where the occlusalproblems exist. The students’ goal is to obtain usefulocclusal contact data with which to treat patients.Training involves multi-bite recordings in excursiveand centric relation. The data is then analyzed indynamic movement. The training software features areforce-mapping in 2- and 3-dimensions, t ime-sequencing of each tooth contact, moving total forcesummation COF, force %/tooth, force%/arch half andforce %/quadrant. Electromyography is synchronizedwith the T-scan for evaluation of timing and sequentialdata. A computer-guided occlusal adjustment is doneusing an essix retainer. The paper marks arecorrelated to the digital data for uniform equilibration.The digital occlusion clinician is taught to use time-sequencing to purposefully delay implants to contactafter natural teeth.

“How It’s Taught: Leaf Gauge (and Beyond)”



Dr. Christopher Orr presented how centric relationrecords are made using the leaf gauge. A casecomplexity assessment is done. The patient’s adaptivecapacity needs to be established. A leaf gauge is oneof the simplest ways to record centric relation. Asufficient number of leaves are placed between theteeth anteriorly so that the posterior teeth are discludedand so that the lateral pterygoid muscles are stretchedand the muscles of mastication are seating the joint.The joint is also being load tested. The literature isinconclusive in terms of whether the leaf gauge is moreor less accurate in relation to other methods ofobtaining centric records. Leaves are added orsubtracted until sufficient thickness of material can beplaced to record centric relation. The sequence oftreatment follows consultation, baseline records,preliminary treatment, provisional restorations, transitionto definitive restorations, and maintenance. Repetitionis needed for teaching equilibration. The leaf gauge is agood entry-level method for load testing the joint andachieving a centric relation and bite record.

Speaker: Dr. Terry E. Donovan“Wear of Tooth Structure and

Restorative Materials”Abstract: Dr. Wendy Gregorius


Dr. Terry E. Donovan discussed the wear of toothstructure and restorative materials and the evidencerelated to wear and why it is not stronger. He providedinformation gleaned from in vitro laboratory studies,showed the predictive ability of data gleaned from“wear” centers, explained the clinical implicationsrelated to materials selection, as well as gave a briefupdate on the wear of composite resin material.



AES Contact 25

What are the hurdles preventing the conduction ofrandom controlled clinical trials (RCTs) related to “wear” ofenamel and restorative materials? The answer includestime, money, the number of subjects required andinvestigator calibration. The main reason for the lack ofRCTs is due to its multifactorial etiology of “wear.” “Erosivetooth wear,” suggests the multifactorial etiology of “wear.”

Attrition is the wear of tooth structure resulting fromtooth-to-tooth contact, which can be through masticationor bruxism or be physiologic or pathologic. Abrasion ispathologic wear of tooth structure due to an abnormalmechanical process. Erosion is chemical loss of toothstructure with no bacteria. The two types of erosion areextrinsic or extrinsic erosion. Extrinsic erosion is a resultfrom the ingestion of acidic foods and beverages. Thelocation of tooth structure is seen on the labial surfacesof the incisor teeth, buccal surfaces of the posterior teethand the occlusal surfaces of the maxillary and mandibulararches. Intrinsic erosion results from bulimia and GERD.It occurs on the palatal surfaces of the maxillary teethand the occlusal surfaces of the mandibular teeth. Fourgroups of patients are at risk for erosion: young females,teenage males, middle-age males and the elderly.Abfraction is the multifactorial loss of tooth structure inthe cervical area involving tooth flexure, toothpasteabrasion and chemical erosion.

The last reason that we do not have RCTs is a lack ofvalidated indices for evaluating and measuring wear.Laboratory studies have been done that show trends. Therougher the porcelain, the greater the wear of enamel.Polished porcelain produces less enamel wear thanoverglazed and unglazed porcelain. Shaded Dicor caused10 times to 15 times the wear of enamel than gold. Theleast abrasive ceramic wore 10 times the amount of enamelwhen to compared to cast gold. Wear in citric acid (pH 4) isconsiderably greater than wear in water. All of the ceramicmaterials tested wore enamel 6 times to 15 timescompared to gold.

In summary, studies regarding enamel wear compared tomaterials showed that it is impossible to compare studies.In-vitro studies do not duplicate intraoral conditions. Allceramic materials wear enamel more than opposingsurfaces of enamel or gold. The hardness of ceramic is notan issue, but the roughness of the ceramic is the criticalproperty. Studies on ceramic material compared to enamelshowed that there is no best ceramic or surface, allceramics have the potential to wear enamel, surface

roughness is the major factor, all external glazes and stainsare abrasive and opaque porcelain and core materials areabrasive and polish is equal to glaze roughness. Thesurface roughness of porcelain is dependent onmicrocrystalline structure, laboratory processing andocclusal adjustment and wear over time. Porcelainpolishing is recommended in the literature. There is a needto polish porcelain post-adjustment. Layered materials aremore esthetic than monolithic materials; however,monolithic restorations are stronger but more abrasive.When gold restorations are compared to ceramic, theyremain the longer lasting restoration.

In summary, wear is a complex process that can hardlybe simulated while controlling all variables. Extrapolation ofthe in-vitro wear results to the in-vivo situation is difficultbecause of interplay with biological variables that aredifficult to mimic. It is not the degree of sophistication, butthe right mix of controllable variables that will make a wearsimulator predictive.

In conclusion, wear of enamel and restorative material isa complex mutifactorial process. Wear of enamel vs.enamel, gold and amalgam is clinically insignificant.Contemporary composite resins have adequate wearresistance in small cavities. All contemporary ceramicmaterials are potentially abrasive to enamel materials.Preferred couplings are enamel with enamel, gold withenamel and porcelain with porcelain. In-vitro wear researchis not correlated to clinical performance. Patient (biological)factors are more important than material factors.Randomized controlled clinical trials are needed.

“The Dynamics of Occlusion”Abstract: Dr. Wendy Gregorius


Dr. John O. Grippo lectured on the dynamics of occlusion.The pathodynamic mechanism of tooth surface lesions ismultifactorial and includes friction (wear), corrosion(chemical degradation) and stress (abfraction). Force can bedynamic or static, and stress is defined as the force per unitarea. Teeth exert forces during swallowing, chewing andbiting. It was proposed that the precise term corrosion orbiocorrosion be used to replace the term “erosion” and to

recognize the mechanisms of stress corrosion and fatiguecorrosion. Corrosion is the loss of tooth substance bychemical action. Causes of biocorrosion can be acidic andproteolytic corrosion. The effects of occlusion on teeth areinfractions, non-carious lesions, carious lesions, completefracture of teeth, cervical dentin hypersensitivity, bruxism,mobility and loss of cementum. Case studies were shownto illustrate the concept of the pathodynamic mechanism.

“Occlusion and Esthetics forDentures/Implant Overdentures”

Abstract: Dr. Doris KoreGraduate Student, Advanced Education Program in


The placement of the anterior teeth in dentures is critical notonly for outstanding esthetics but to prevent anteriorrestriction for the envelope of function. Quality, quantity andpreservation of bone are the key factors in dentistry.Porcelain teeth preserve bone and everything we do indentistry is to preserve bone. Plastic teeth destroy bonebecause there is no stability.

The speaker presented a way to place anterior teeth thathas served him well for forty years. The anterior teethshould be set with anatomical harmony as follows: Mark theheight of the canine fossa and the insertion of the frenumand the midpoint between the two is usually 20 mm fromthe incisal edge 20 mm down and 10 mm out from theincisive papilla. When looking straight at the patient youshould see only the mesial half of the cuspid. For verticaldimension of occlusion and phonetics, place speaking waxand have the patient read until they have a beautiful “S”clearance. Have 1 mm clearance for freeway space—speech. The edentulous mandible is like a tripod that haslost one leg. With the two condylar elements, the anteriordeterminant becomes the third leg on the tripod.

The most critical step in removable prosthetics is toaccurately record centric relation. The speaker showed theuse of a central bearing point for use with completedentures as well as in combination cases where there areteeth present in one arch that will occlude with a denture inthe opposing arch. The central bearing device works in theedentulous mouth like an anterior deprogrammer works onnatural teeth.A Gothic arch tracing confirms you are in

centric. A central bearing device without tracing is all right. Everything we do in dentistry is to preserve bone. The

speaker also demonstrated the use of custom gold andother metal occlusal surfaces during the presentation.

“Programming Complex RestorativeCases: A Global Approach”

Abstract: Dr. Doris KoreGraduate Student, Advanced Education Program in


The purpose of this lecture was to present a diagnosticmethod based on the concept of “global” diagnosis.Complex restorative dentistry is interdisciplinary dentistry.The speaker’s goal and vision has been to teachinterdisciplinary dentistry. Interdisciplinary dentistrypurposefully or indirectly alters the gingival architecture,which leads to restorative dentistry. At the end of gingivaltreatment, it should become restorative dentistry. Complexrestorative cases in the past were occlusally driven, but nowwe know that the gingival architecture has to be taken intoconsideration or the teeth have to be moved around ortaken out. So now complex restorative cases becomeinterdisciplinary dentistry.

After the collection of data, it used to be restoratively orocclusally driven. Occlusion is important, but the teeth haveto be in the right place to be esthetic and also function well.Facially generated diagnosis by Drs. Kois and Spearsuggest that occlusion is important, but the teeth have tobe in the right place for function and esthetics as well. Overthe last 40 years we have worked through clear-cut rules ofocclusion and we have set ways of working throughocclusion and coming to the end product. In the last 15years the speaker and his partner has been trying to teachthis facially generated diagnosis with a more simplified andmore teachable approach and called it “global” analysisdiagnosis. Comparing the “global” analysis diagnosis to amedical model makes it easier to understand. Form isthrough measurements and photographs. Regionalincludes diagnostic records, and regional treatmentplanning involves regional data collection, experiencebased treatment planning and error based revisedtreatment planning. These alone are not good teachers.“Global” diagnosis is naming the problem: “Global” and



AES Contact 27

“Regional” data collection, “Global” interdisciplinarydiagnosis, the sequential treatment plan is based ondiagnosis not experience, and “Regional” data modifies a“Global” plan. How the data is handled after it has beencollected leads us to the five core questions to beasked—What is the face height, lip length and mobility,gingival line, tooth length and CEJ? The averagenumbers for a 30 year old are 1:1, 20-24 mm, 6-8 mm,straight and 10 mm. The average numbers will be a littledifferent for older individuals. Any number that is outsidethese numbers will help us make a diagnosis. There aresix tools to correct this problem, which includeconnective tissue graft, crown lengthening, intrusion,extrusion, plastic procedures (Botox and fillers) andorthognathic surgery. Basically they are gingivalarchitecture problems.

Think of interdisciplinary dentistry as simply altering adenture. Somehow make it into a restorative case. Find atooth that you like and leave it alone and work on theones that you do not like.

“Combining Esthetics and Occlusion for Longevity”

Abstract: Dr. Alfredo ParedesGraduate Student, Advanced Education Program in


The most important reason for why people go to the dentistis for appearance related issues. In a patient whose currentocclusal condition is affecting the masticatory system anddentition, it is important to understand how we can test thatthe new restorations will work and last the longest. For this,it is necessary to achieve “end-to-end” harmony that willprovide the appropriate occlusal contacts and disclusion ineccentric movements of the mandible, reality views thatconsist of educating the patient about his or her dentalconditions. This involves using photos and acomprehensive bite analysis, which involves analysis of thechewing cycle of a patient and force management, whichlowers the occlusal forces. Lateral and workinginterferences activate the masticatory muscles, which thenincrease the biting forces, which will affect the longevity ofthe restorations. Comprehensive dentistry requires anesthetic intraoral mock-up and a direct technique, which isdone by bonding composite resin to the ideal occlusion incentric relation. This will allow for determination of thelength of the teeth, occlusal vertical dimension, occlusalplane and stabilization of the occlusion. Stability of thecomprehensive treatment is monitored over time by using adual arch occlusal appliance (E-Appliance).
