Discuss in detail the various theorems governing retention in orthodontics
 Introduction
 Definition of retention
 Theorems of retention
- Theorem 1 – teeth that have been moved tend to return to their
former positions
- Theorem 2 – elimination of the cause of malocclusion will prevent
recurrence
2
2
2
-
2.
Theorem3 – malocclusion should be over corrected as a safety
factor
Theorem 4 – proper occlusion is a potent factor in holding teeth in
their corrected position
Theorem 5 – bone and adjacent tissues must be allowed to
reorganize around newly positioned teeth
Theorem 6 – If the lower incisors are placed upright over basal
bone, they are more likely to remain in good alignment
Theorem 7 – corrections carried out during periods of growth are
less likely to relapse
Theorem 8 – the farther teeth have been moved, the less likelihood
of relapse
Theorem 9 – arch form, particularly in the mandibular arch cannot
be altered permanently by appliance therapy
Discuss the various schools of thought on retention philosophy and its role in
avoiding relapse?
 Schools of thought on retention philosophy
- Occlusion school- by Kingsley
- Apical base school – by Alex Lundstorm

- Incisal edge of lower incisor should be placed on the A-pog
linear 1mm in front of it
- Lower incisor apices should be spread distally to the crowns
more than generally and apices of lateral incisors spread more
than central incisors
- Apex of lower canine should be positioned distal to the crown
- All four lower incisor apices must be in the same labiolingual
plane
- Lower cuspid root apex must be positioned slightly buccal to
the crown apex
- Lower incisor should be slenderized as needed after treatment

Retention strategies:


Forward tongue placement habit requires special consideration
3 important situations for indefinite retention
- Pt who had generalized spacing , in which arches are large and
tooth structure are not
- In circumstances of lip competency
- In adult pts who have moderate upper and lower incisor
crowding and whose incisor are mildly upright (cl 2 div 2
cases)
 Special considerations to periodontally compromised patients
 Special considerations for cross bite correction ,rotation correction

- Conclusion
Condylar adaptation in class III and class III malocclusion?
 Condylar position in normal occlusion
 In class II malocclusion
- Path of closure from post rest position to occlusion without
functional disturbances
- Path of closure of mandible is upward and forward without
displacement
- Path of closure with posterior displacement
 In class III malocclusion
- Straight path of closure
- Path of closure with anterior displacement
- Path of closure with posterior displacement
 In pseudo class III malocclusion
 Rickett’s study of condylar adaptation
 Related studies of condyle and fossa
Miniplates

2. Presurgical objectives
Goals –
1. Align and level teeth without concern for dental occlusion.
2. Establish proper anterior-post. and vertical position of the incisors.
3. Achieve arch compatibility.
Procedures that need to be done before surgery include –
 Alignment
 Leveling – by intrusion
 Arch compatibility
2
Procedures that can be done before and/or after surgery –
 Post. crossbite correction
 Leveling by extrusion
2
Procedures necessary after surgery –
 Settling and leveling by extrusion
 Root paralleling at osteotomy sites
 Detailed tooth positioning.

Step 2 - Determine the Ideal Vertical Position for the Upper Incisor.
Step 3 - Autorotation of the Occlusal Plane.
Step 4 - Mandibular Movement.
Steps 5-10 - Completing the Tracing.
