Instructions For Use:
For a detailed explanation of the osteotomy preparation andimplant placement guidelines, refer to the appropriateSurgical Manual(s).
Description:
BIOMET 3i Dental Implants are manufactured frombiocompatible titanium or titanium alloy. BIOMET 3i DentalImplants include various surface treatments. For specific productdescriptions refer to individual product labels.
Indications For Use:
BIOMET 3i Dental Implants are intended for surgical placementin the upper or lower jaw to provide a means for prostheticattachment in single tooth restorations and in partially or fullyedentulous spans with multiple single teeth, or as a terminal orintermediary abutment for fixed or removable bridgework, and
to retain overdentures.
Contraindications:
Placement of dental implants may be precluded by both patientconditions that are contraindications for surgery as well ashypersensitivity to commercially pure titanium or titanium alloy(including vanadium, aluminum, and calcium phosphate).
BIOMET 3i Dental Implants should not be placed in patientswhere the remaining jaw bone is too diminished to provideadequate implant stability.
Warnings:
Excessive bone loss or breakage of a dental implant may occur
when an implant is loaded beyond i ts functional capabi lity.Physiological and anatomical conditions may affect theperformance of dental implants.
Mishandling of small components inside the patients mouthcarries a risk of aspiration and/or swallowing.
Forcing the implant into the osteotomy deeper than the depthestablished by the drills can result in damage to implant, driver,or osteotomy.
For short implants, clinicians should closely monitor patients forany of the following conditions: peri-implant bone loss, changes
to the implants response to percussion or radiographic changes
in bone to implant contact along the implants length. If theimplant shows mobility or greater than 50% bone loss, theimplant should be evaluated for possible removal. If a clinicianchooses a short implant, then the clinician should consider a
two-stage surgical approach, splinting a short implant to anadditional implant, and placement of the widest possible fixture.In addition, the clinician should allow longer periods forosseointegration and avoid immediate loading.
Reuse of BIOMET 3i Products that are labeled for single-use mayresult in product contamination, patient infection and/or failure of
the device to perform as intended.
MRI Statement:
BIOMET 3i Dental Implants have not been evaluated for safetyand compatibility in the Magnetic Resonance Imaging (MRI)environment. BIOMET 3i Dental Implants have not been tested
for heating or migrat ion in the Magnetic Resonance Imagingenvironment.
Precautions:
These devices are only to be used by trained professionals.The surgical and restorative techniques required to properlyutilize these devices are highly specialized and complexprocedures. Improper technique can lead to implant failure,loss of supporting bone, restoration fracture, screw looseningand aspiration. When the clinician has determined adequateprimary stability is achieved, immediate functional loading canbe considered.
The following should be taken into consideration when placingdental implants: bone quality, oral hygiene, and medicalconditions such as blood disorders or uncontrolled hormonalconditions. The healing period varies depending on the quality of
the bone at the implantation site, the tissue response to theimplanted device and the surgeons evaluation of the patientsbone density at the time of the surgical procedure. Properocclusion should be evaluated on the implant restoration toavoid excessive force during the healing period on the implant.
It is recommended that implants less than 4mm diameter NOTbe placed in the posterior regions.
Sterility:
All dental implants are suppl ied sterile and are labeled STERILE.All products sold sterile are for single-use before the expirationdate printed on the product label. Do not use sterile products if
the packaging has been damaged or previously opened.Do not re-sterilize.

Introduction And Treatment Planning
These instructions were designed to serve as a
reference guide for dental practitioners
utilizing Implants and Surgical
Instruments.
The design of BIOMET 3i Implants and SurgicalInstruments enable the practitioner to place implantsin edentulous or partially edentulous mandibles ormaxillae in order to support fixed and removablebridgework or single tooth crowns and overdentures.
General Information:The success of any dental implant systemdepends upon proper use of the componentsand instrumentation. This manual is not intended
for use as a substitute for professional training
and experience.
Treatment Planning:Patient Evaluation And SelectionSeveral important factors must be considered whenevaluating a patient prior to implant surgery. Thepresurgical evaluation must include a cautious anddetailed assessment of the patients general health,current medical status, medical history, oral hygiene,motivation and expectations. Factors such as heavy
tobacco use, masticatory function and alcoholconsumption should also be considered. In addition,
the clinician should determine if the case presents an
acceptable anatomical basis conducive to implantplacement. An extensive intraoral examination shouldbe undertaken to evaluate the oral cavity for anypotential bone or soft-tissue pathology. The examinershould also determine the periodontal status of the
remaining teeth, the health of the soft tissue and thepresence of occlusal abnormalities such as bruxism orcrossbite. The presence of other conditions that couldadversely affect any existing natural dentition or
healthy soft tissue surrounding the implant should alsobe evaluated.
Diseases of the mucous membrane and connectivetissues, pathologic bone disease and severemalocclusion could affect the determination of
whether a patient is a suitable implant candidate.
The use of anticoagulants and the existence ofmetabolic diseases, such as diabetes, allergies, chronicrenal or cardiac disease and blood dyscrasia couldsignificantly influence the patients ability tosuccessfully undergo implant procedures.
If the patients medical history reveals an existingcondition or signals a potential problem that maycompromise treatment and/or the patients well-being, consultation with a physician is recommended.
BIOMET 3i T3 Platform-Switched Implants areintended to be used for surgeries where the clinician
would like to medialize (platform-switch) theimplant/abutment junction.

Preoperative Planning
Preoperative Planning:Proper treatment planning, as well as the selection of theproper implant length and diameter, are crucial to thelong-term success of the implant and restoration.
Before an implant can be selected, the anatomicalfoundat ion avai lable to receive the implant must becarefully assessed. Several steps should be taken tocomplete the evaluation:
1. Clinical examination of the oral cavity can provideimportant information about the health of the soft
tissue at the proposed implant site. Tissue tone andthe state of the superf icial tissues should be evaluated.In addition, the patient should demonstrate anadequate dimension of attached gingiva or keratinized
tissue at the site selected for implantation. In part iallyedentulous cases, the periodontal status of theremaining dentition should be assessed andinteraction between the implant restoration and theadjacent natural dentition should be considered.
2. The bony foundation and ridge need to be clinicallyanalyzed to ensure the presence of properdimensions and the amount of bone for implantplacement. At least one millimeter of bone should bepresent at the buccal and lingual aspects of the implant
following placement. During the planning stage, it isuseful to measure the existing bone foundation.
CT Scans:Computed tomography (CT) scans help surgeons viewparts of the body with three-dimensional images.Image-guided surgical planning allows surgeons to seeanatomical landmarks such as nerves, sinus cavities andbony structures in order to plan for the placement ofdental implants and prostheses.
Through the use of CT scans, clinicians are able tomore precisely measure the locations of anatomicalstructures, dimensions of the underlying bone andascertain bone densities in order to plan and treatclinically demanding cases.
Radiographic Marking Balls (RMB30)The vertical height of the bone can be determinedradiographically. Accurate measurement of the verticaldimension on the radiograph facilitates the selection of
the appropriate implant length. This helps to avoidimplant placement into the maxillary sinus, the floor of
the nose or the mandibular canal and preventsperforation of the inferior aspect of the mandible.Measurements can be made directly on the panoramicradiograph using a millimeter ruler. Corrections shouldbe made for the degree of enlargement produced by theparticular radiographic equipment.
Radiographic marking balls of a known dimension can beembedded in a plastic template prior to radiographicexamination. Once the radiograph is taken and the metalmarking balls are visible on the image, measurementscan be taken to determine the amount of bone available
for implant placement.
To calculate the distortion factor, a simple
formula can be utilized: (5 A) x B = the
amount of actual bone available.
Formula Key = Radiographic marking ball = 5mm in diameter. A = Size of marking ball image on radiograph. B = Length in millimeters on the radiograph of
available bone between the crest of the ridgeand the inferior alveolar canal.
Example:A = 6.5mmB = 14mm
Therefore: (56.5) x 14 = 10.76mm actual bone available
NOTE: A 2mm margin of safety, from the apical end of the implant
to the adjacent vital structure, should be considered.

Top-Down Treatment Planning
In its simplest form, top-down treatment planning refersto a guideline whereby the desired restorative result isconsidered first, leading to consideration of theappropriate prosthetic platform and subsequent implant
selection based on bony anatomy and the size of themissing tooth.
A top-down treatment planning methodology willprovide maximum biomechanical stability and allow forsoft-tissue flaring by utilizing an implant with a prostheticplatform slightly smaller in diameter than the emergencediameter of the tooth being replaced. The wideselection of Implants allows clinicians tomatch the size of the prosthetic platform to therestoration it will eventually support, while allowing fordifferent bone volumes and anatomical features at the
implant site. Implant and healing abutment selections arebased upon the relationship of several key measurements:
The emerging dimension of the crown in relation to
the diameter of the prosthetic platform of the implant
The height and diameter of the intended restorationat the tissue exit point
The bone volume at the implant site in relation to thediameter of the implant body
The Emergence Profile (EP) Healing Abutment Systemconsists of healing abutments of various diameters andheights for shaping the soft tissue to replicate thegeometry and gingival contours of natural dentition.

Surgical Precautions
Clinical Considerations:True bone contours can only be evaluated after tissue
flaps have been reflected at the time of surgery or withpreoperative high quality CT scans. Even if bone
dimensions are painstakingly measured prior to surgery,the doctor and patient must accept the possibility thatinadequate bone anatomy might be discovered duringsurgery and preclude implant placement.
During the presurgical planning phase, it i s important todetermine the interocclusal clearance - the actual spaceavailable between the alveolar crest and the opposingdentition - to confirm that the available space willaccommodate the proposed abutment and thedefinitive crown restoration. The height required by theabutment may vary with the type of abutment;
therefore, the surgeon and restorat ive dentist should
carefully evaluate the abutment size. The definitiveprosthesis should be conceptually designed prior to theplacement of the implant.
Diagnostic casts can be used preoperatively to evaluatethe residual ridge and to determine the position andangulation of all implants. These casts allow the clinician
to evaluate the opposing dent ition and its effect on theimplant position. A surgical guide stent, which is critical
for determining the precise position and angulat ion ofthe implant, can be constructed on the diagnostic cast.
Several software companies offer planning softwarethat allow clinic ians to plan implant placement three-dimensionally in conjunction with CT scans. From planscreated in these software packages, surgical guides canbe made to aid in the pre-angulation and placementof implants.
To prevent damage to the bone tissue and to preventcompromising osseointegration by the bone overheatingduring high speed drilling, copious irrigation with sterile
water or sal ine solut ion is mandatory during alldrilling procedures.
Bone surgery utilizes a high-torque electric drilling unitthat can be operated in forward and reverse modes atspeeds ranging from 0 to 2000rpm, depending on thesurgical requirements. Sharp instruments of the highestquality should be utilized during implant site preparation
to reduce possible overheating and trauma to the bone.Minimizing trauma enhances the potential for successfulosseointegration.
The time elapsed between surgical placement of the
implant and definitive abutment placement can vary orbe modified, depending on the quality of the bone at theimplantation site, bony response to the implant surfaceand other implanted materials and the surgeonsassessment of the patients bone density at the time of
the surgical procedure. Extreme care must be taken toavoid excessive force being applied to the implant during
this heal ing period.

Cleaning And Sterilization
Single use drills/burs are supplied sterile and shouldbe properly disposed of after each procedure.Reusable drills/burs and instrumentation are suppliednonsterile and must be sterilized prior to use.
Nonsterile items must be removed from thepackaging before sterilization.
Multiple sterilizations may affect the flow of fluidthrough internally irrigated drills . The dril ls should beinspected following each sterilization cycle todetermine if fluid flows through the irrigation ports.
Although the surgical dril ls are constructed of stainlesssteel, these should be adequately dried prior topackaging for sterilization and again after thesterilization cycle. Reusable drills are recommended tobe replaced after15 osteotomy preparations, subject
to the information below.
The end of life for surgical instruments is normallydetermined by wear and damage. Surgical instrumentsand instrument cases are susceptible to damage for a
variety of reasons including prolonged use, misuse,rough or improper handling. Care must be taken toavoid compromising the intended performance of
the instrument.
Visually inspect each instrument before and after eachuse for damage and/or wear.
To extend the useful life of Instruments,certain procedures should always be followed:
Cleaning:1. After use, place drills into a beaker of plain water,
mild soap or specialized cleaning solution.2. Rinse with tap water for a minimum of two
minutes while brushing with a soft bristled brushto remove visible debris. Clean the interior lumenwith a thin wire to remove any remaining debris.
3. Place instruments in an ultrasonic bath containingenzymatic detergent for five minutes.* Scrub theinstruments again with a soft bristled brush and
ream the interior lumen to remove any remainingdebris.4. Rinse and flush the instruments for one minute
using tap water.5. Inspect visually for any remaining bone fragments
or debris and scrub as necessary.
Sterilization:6. Remove the bur block from the surgical tray.
Scrub the surgical tray and block with a soft bristlebrush and mild soap. Rinse thoroughly.
7. Place the components into the surgical tray andpour ethyl alcohol (do not use rubbing alcohol)over the burs and tray to remove soap residueand minerals from the water. This step isimportant to help prevent corrosion and spotting.Let the components dry before wrapping.
8. Wrap the surgical tray in paper or autoclave-approved bags twice to prevent a tear of theouter packaging from contaminating sterileinstruments.
9. Steam gravity sterilization method Minimum oftwenty minutes at a temperature of 270 275F(132 135C).**
Pre-vacuum sterilization method Minimum offour minutes ( four pulses) at a temperature of270 275F (132 135C).**
10. Dry for 30 minutes. Drying times may varyaccording to load size.
NOTES:
1. Multiple sterilizations may affect the flow of fluid
through internally irrigated burs. After each use, ream
the burs individually with wire to remove any bone
fragments or debris that will prevent the flow of water.
This is done prior to the sterilization cycle.
2. Do not remove drills, instrumentation or the surgical
tray from the autoclave until the dry cycle iscomplete. Very Important!
3. These guidelines DO NOT apply to the cleaning and
sterilization of your powered instrumentation. Please
follow your powered instrumentation manufacturers
instructions.
Please refer to P-IFSCSS for complete instructions onthe steril ization and care of stainless steel.
*ENZOL enzymatic detergent was used to validate this process, per the
manufacturers dilution recommendation.
**Post sterilization devices should be thoroughly dried to mitigate the risk
of stainless steel corrosion (30 minutes is typical).

Bone Density
The protocols detailed in this Surgical Manual havebeen developed to include more specific informationabout drill selection when working in various bonedensities. However, the clinician is responsible for
assessing the bone density of the anatomy whendetermining the appropriate protocol.
The various bone densities can be typicallycharacterized by the following:
Dense (Type I) A thick cortical layer and a veryhigh density trabecular core
Medium (Type II & III) A cortical layer ofmoderate thickness with a reasonably dense
trabecular core
Soft (Type IV) A thin cortical layer and a lowdensity trabecular core

Why Tapered Implants Are Different3i T3TM Tapered Implants
Due to the geometrical differences that exist between atapered and a paral lel wal led implant, there are severalimportant technique adjustments thatare required.
In all tapered implant placement procedures,the surgeonshould determine the appropriate vertical position of
the implant (supracrestal, crestal or subcrestal) at the
time of osteotomy preparation. The surgeon shouldprepare the tapered osteotomy so that when the implantis fully seated, the implant seating surface is at the desiredposition. The Tapered Implant Depth/Direction Indicator(NTDI) was designed to simulate the tapered implantposition prior to placement.
After preparation of the osteotomy with the final shapingdrill, flush the osteotomy with sterile water or salinesolution and suction out any remaining debris. Select thecorresponding NTDI and place the tapered end into theosteotomy. Check the platform position (crestal orsubcrestal) of the NTDI in relation to the adjacent bone.This position locates where the platform of the taperedimplant will be positioned when properly placed. If duringplacement with the drill unit, the tapered implant platformis higher in relation to the bone than was demonstrated
with the NTDI platform, the clinician should considerusing a hand ratchet to complete the implant placement so
that the tapered portion of the implant body conforms
correctly with the tapered portion of the osteotomy(Figure 1. Proper Subcrestal Placement).
Over Preparingthe osteotomy depth and then placingthe implant at a crestal level may result in a conical spacearound the apical and coronal aspects of the taperedimplant minimizing thread engagement (Figure 2. OverPrepared Subcrestal Placement). This placement positionmay result in decreased implant to osteotomy contact,
with contact occurring only along the parallel coronalportion of the implant, resulting in decreased stability of
the implant.
Under Preparingthe osteotomy depth and then placingthe implant more apical relative to the prepared depthmay result in the implant stopping short of the desiredplacement level. The implant may then spin and loseprimary stability (Figure 3. Under PreparedSubcrestal Placement).

ACT
The Quad Shaping Drills (QSDs) are used to preparethe osteotomy for placement ofTapered Implants.
The BIOMET 3i Depth Measurement System includesdrill depth marks on the ACT Twist Drill thatcorrespond to the placement of the implant via a well-established procedure. The BIOMET 3i protocol
follows the principles of protecting the implant frompremature loading by placing the implant subcrestally.
The Quad Shaping Drills have been designed withgeometrical depth landmarks to assess proper depthrather than laser etched markings. The clinician shouldbecome familiar with these depth landmarks to prevent
over or under preparation of the osteotomy site.
Shaping Drill Speed:QSDs should operate between 1200 1500rpm.
QSDs cut efficiently; reducing the downward forcewill al low the drill to cut without detectable chatter.
Shaping Drill Technique: For either crestal or subcrestal implant p lacement,
drill to the top of either the crestal or subcrestaldepth landmarks on the QSD (full depth - seeillustration to the right).
Do not pump the shaping drill as you might do witha twist drill when creating the osteotomy as it maydistort the dimensions of the osteotomy. Theshaping drill should be advanced once to full depth,
then be removed without any pumping action. Once the shaping drill has reached the desired
depth, pull it out of the site without running the drill.If the drill does not pull out easily, tap the foot pedal
while pulling the drill out. In addition to preservingthe integrity of the osteotomy site, this techniquemaximizes autogenous bone recovery from theshaping drill flutes.
When placing a tapered implant in soft (Type IV)
bone, the surgeon should consider undersizing theosteotomy.The final drill diameter should match
the implant diameter, but be l imited to 8.5mm inlength. This will create an osteotomy of properdimension in the dense cortical bone to receive theimplant, but will slightly undersize the osteotomy in
the cancellous region.
It is required that the clinician tap the
osteotomy when placing a Tapered Implant in
Dense (Type I) Bone.
NOTE: During preparation of the osteotomy, the QuadShaping Drill should advance into the osteotomy using lightpressure. The need to push heavily on the shaping drill mayindicate the need to replace the shaping drill, the need to
tap or that the previous drill depth was inadequate.

Twist Drill Depth Marking System (Contd)3i T3TM Tapered Implants
The Depth Marks measurement system
provides a mark on the drill that corresponds to theplacement of the implant via well-establishedprocedures. The original BIOMET 3i protocol follows
the principles of protecting the implant from prematureloading by placing the implant subcrestally.
Drilling DepthThe drilling depth with the Twist Drill will vary dependingon the type of placement related to the bone crest.
The depth marks are specific for subcrestal implantplacement only. There are no specific depth marks on
the drills for crestal or supracrestal placement.
The drill depth marks do not indicate implant lengths.Rather, the drill depth marks represent the length of theimplant with a standard 1mm cover screw in place. As aresult, to place an implant and cover screw subcrestallyrequires drilling to the middle of the single line depthmark or the beginning or end of the broad band depthmark on ACT Drills. For crestal placement, drillhalfway before the corresponding depth mark for theimplant length. For supracrestal placement, the drilldepth mark should remain above the bone by 1mm for
the cover screw plus the implant collar height. Pleaserefer to the diagram at the bottom of page 13 for more
information on supracrestal placement.
Implants are packaged with a 0.4mm tall cover screw.However, the protocols for these implants do not differ
from the protocols for BIOMET 3i Implants packagedwith a 1mm tall cover screw.

The Tapered Implant Depth/Direction Indicator is used to simulatethe implant platform position prior to placing the implant.
Step 1When using the NTDI and after preparation of the osteotomy withthe final shaping dri ll, flush the osteotomy with ster ile saline solut ionand suction out any remaining debris (Figure 1). This will ensure that
the osteotomy is clear of debris that could prevent the NTDI fromfully seating.
Step 2Verify the NTDI platform position in reference to the crest of thebone. This also verifies the depth of the osteotomy that has beencreated. The NTDI platform should be at the level you desire the
implant platform to attain. If the NTDI platform is too high versus thedesired position, then re-drilling to the appropriate depth is required.If the NTDI platform is too deep versus the desired position, thisindicates some degree of osteotomy over preparation has takenplace. To ensure proper engagement of the implant, it must be seated
to the depth demonstrated by the NTDI. A longer implant can beconsidered. The clinician may consider verifying the position of theNTDI with a radiograph (Figure 2).
Step 3When placing the implant, the implant platform should reach thesame position that the NTDI platform previously attained. If theimplant platform is positioned higher in relation to the crest of the
bone than the platform of the NTDI previously demonstrated, or ifthe surgical motor stalls prior to ful l placement of the implant due toinsufficient torque, then hand ratcheting is recommended to achieve
the proper final implant seating position (Figure 3).
These guidelines are designed to help ensure good bone-to-implantcontact and primary stability of the implant.

Implant Bone Taps And Bone Tap Kit (NTAPK)3i T3TM Tapered Implants
Dense Bone Taps
When placing a tapered implant in Dense (Type I)Bone, tapping the osteotomy prior to implant
placement is required (Figure 1).
Dense Bone Taps are available to fully thread the entireosteotomy. These Dense Bone Taps are both length anddiameter specific to correspond to each tapered implant(Figure 2).
NOTE: Dense Bone Taps shown on this page have replaced
the Standard Tapered Bone Taps.
Tapered Implant Tap Kit (NTAPK)For Use With Tapered Implants In Dense BoneWhen placing a tapered implant, the need to tap theosteotomy may arise, especially in dense bone. The DenseBone Tap Kit has a specific tap that matches each taperedimplant, which then facilitates site specific preparation to aid in
final implant placement. Fully seat the tap to the leveldemonstrated by the NTDI.
NOTE: It is not uncommon for the drill unit to stall before
the tap is completely seated. Final seating of the Dense Bone
Tap may require the use of the Ratchet Extension and the
Ratchet Wrench.

6b. Flush the osteotomy with sterile saline solution. Using suction, remove anyremaining drilling debris from the osteotomy before proceeding with theDepth/Direction Indicator (NTDI).
6c. Insert the tapered end of the 5mm x 8.5mm (NTDI585). This will simulatethe position of the implant platform in relat ion to the crest of the bone. If theposition of the NTDI does not indicate proper osteotomy depth, adjust thedepth of the osteotomy with the 5mm x 8.5mm Quad Shaping Drill orconsider a longer length implant if the site has been over prepared. Re-
evaluate with the 5mm x 8.5mm NTDI. Thread a suture through the holeto prevent accidental swal lowing.

Twist Drill Depth Marking System (Contd)3i T3TM Parallel Walled Implants
The Depth Marks measurement systemprovides a mark on the drill that corresponds to theplacement of the implant via well-establishedprocedures. BIOMET 3is original protocol follows theprinciples of protecting the implant from prematureloading by placing the implant subcrestally.
Drilling DepthThe drilling depth with the Twist Drill will varydepending on the type of placement related to thebone crest.
The depth marks are specific for subcrestal implantplacement only. There are no specific depth marks on
the drills for crestal or supracrestal placement.
The drill depth marks do not indicate implant lengths.Rather, the drill depth marks represent the length of
the implant with a standard 1mm cover screw in place.As a result, to place an implant and cover screwsubcrestallyrequires drilling to the middle of thesingle line depth mark or the beginning or end of thebroad band depth mark on ACT Drills. For crestalplacement, drill halfway before the correspondingdepth mark for the implant length. For supracrestalplacement, the drill depth mark should remain above
the bone by 1mm for the cover screw plus the implantcollar height. Please refer to the diagram at the bottom
of page 40 for more information on supracrestalplacement.
Implants are packaged with a 0.4mm Cover Screw.However, the protocols for these implants do notdiffer from the protocols for BIOMET 3i Implantspackaged with a 1mm Cover Screw.

5. Once proper alignment is verified using the Direction Indicator, proceed withthe 2.75mm Twist Dril l to the desired depth for implant placement in
medium bone (Type II and III). Proceed with the 3mm Twist Drill to thedesired depth for implant placement in Dense (Type I) Bone.The recommended drill speed is 1200 1500rpm.
Instruments needed:2.75mm Twist Drill for medium (Type II and III) bone3mm Twist Drill for dense (Type I) bone
Optional Tapping Step: For Dense (Type I) BoneIf placing a 3i T3 Parallel Walled 3.25mm(D) Implant in Dense (Type I) Bone,using a Bone Tap is recommended.
Using the Handpiece Connector, advance the tap into the prepared site atapproximately 15 20rpm. It is not uncommon for the drill unit to stall before
the tap is completely seated. Final seating of the Dense Bone Tap may require theuse of the Ratchet Extension and the Ratchet Wrench.
Instruments needed:Handpiece Connector (MDR10)Bone Tap (MTAP1 or MTAP2)Ratchet Wrench (WR150)Ratchet Extension (RE100 or RE200)
Proceed to step 1 on page 53for implant placement.
