Dental presentation on malocclusion

1. MALOCCLUSION

2.  Occlusion
 Maloclusion

3. Types of maloclussion
 Classes

6. Diagnostic aids in orthodontics
1. Case history
2. Clinical examination
3. Study models
4. Certain radiographs
a. Periapical radiographs
b. Lateral radiographs
c. Orthopantomograms (OPG)
d. Bitewing radiographs
5. Facial photographs

7. Uses of study models
1. Assess and record dental anatomy
2. Assess and record intercuspation
3. Assess and record arch form
4. Assess and record the curves of occlusion
5. Evaluation occlusion with the aid of articulators
6. Measures progress during treatment
7. Detect abnormality e.g. localized enlargements, distortion arch form, etc.
8. Calculate total space requirements / discrepancies
9. Provide record before, immediately, after andseveral years following treatment
for the purposes of studying treatment procedures and stability

8. Management of maloclussion
 Removable appliances
 Fixed orthodontics

9. Methods of gaining space
 Extraction
 Proximal stripping
 Expansion
 Distalization
 Uprighting
 Derotating
 Proclination of anterior teeth

10. Goals of orthodontic treatment
 Improving aesthetics – best possible!
 Facial aesthetics
 Dental aesthetics
 Improve oral functions
 Achieve normal/functional Occlusion
 Normal Occlusion – Andrews six keys
 Functional Occlusion in CR - Roth
 Prevent dental disease eg dental caries, Perio Dx
 Stability of the results
 Mn incisor balanced over basal bone
