Orthodontic diagnosis ... Dr.Mohammed hassan

Introduction

deals with recognition of the various characteristics of the malocclusion

A brief examination of the developing occlusion should be carried out around 7-8 years to check presence of permanent teeth, their position , and detect any problem may be affected on normal eruption

1. Essential diagnostic aids

2. Supplemental diagnostic aids

1. Case history

2. Clinical examination

3. Study models

4. Certain radiographs;

Periapical

Bitewing

O.P.G

5. Facial photographs

1. Specialized radiographs ex:-

a-cephlometric radiographs

b-occlusal intra-oral films

2. Electromyographic.

3. Hand wrist radiographs.

4. Endocrine tests

5. Estimation of basal metabolic rate

b. identification

c. psychological benefits

For purpose of …..

1. Age helps in diagnosis , treatment planning and growth prediction .

2. growth modification procedures using functional and orthopaedicappliances are carried out during growth period.

3. Age is more important factor in orhtodontic treatment planning.

Dental or Orthodontic treatment include ….

1. Clift lip and palate .

2. Trimmed or extracted of natal

or neonatal teeth

Most important treatment in this age include ….

1. Interceptive treatment

2. Treated of any premature contact with functional shift or mandibular displacement

3. Skeletal cl.III can be observed by presence of ngative over-jet or mandibular prognathism can be treated at this age

The treatment include ….

1. Interceptive treatment .

2. Correction of cross-bite.

3. Serial extraction .

4. Skeletal cl.II due to maxilla .

5. Skeletal cl.III due to maxilla or mandibule .

6. Checking of supernumerary teeth by X-ray

This is best time for use of fixed appliance .

Also removable appliance can be used in this age .

This is important in the treatment planning, as the timing of growth events such as growth spurts is different in males and females.

Race of the patient is very important …

For negroid patient with bi-max. dntoalveolarprotrusion and lip competent no Orthodontic treatment need .

Address and occupation helps in evaluation of socio-economic status of the patient and the parents.

Also it can affected spring design

It should explore several related areas: -

1. The patient's motivation for treatment :-

A. external

B. internal

3. Esthetic

Patient with Epilepsy, History of blood dyscrasias ,Diabetic patient ,Rheumatic fever ,Cardiac anomalies … may rquire special precaution .

patient should be ask bout y drug used .

Patient should be ask about any acute debilitating condition .

It includes information on the …

1. age of eruption of the deciduous and permanent teeth.

2. history of extraction, decay, restoration and trauma to dentition.

Helps in evaluation of patient and parent’s attitude towards treatment.

History of habits :-history of any abnormal habits like thumb sucking ,

nails biting lip biting and mouth breathing should be taken as they influence the development of dento-alveolar stracture

Skeletal Cl. II , Cl.III malocclusions and congenital conditions such as clefts of lip & palate, crowding are inherited.

It include

1. information on the condition of the mother during pregnancy and the type of delivery.

2. Drugs like thalidomide or affectation with some infection during pregnancy like german measles can results in congenital deformities of child.

It include ….

1. the type of feeding,

2. presence of habits

3. and on the milestones of normal development
