Abstract
|
|
|
The purpose of this study was to investigate the change and stability of the cant of occlusal plane affected by the use of Class II elastic in Class II individuals. Materials consisted of lateral roentgenocephalograms of 29 patients treated with full brackets system. Cephalograms was taken at following 3 stages; the beginning of orthodontic treatment, the beginning of retention, 2 years after orthodontic treatment.
Measurements were done at following angles and distance. 1. SN-Occlusal plane
2. Palatal plane-Occlusal plane
3. Mandibular plane-Occlusal plane
4. AB plane-Occlusal plane
5. Occlusal plane inclination
6. Xi-Occlusal plane distance
The results were as follows;
1. The changes of the occlusal plane mainly occurred within the alveolar process. 2. The SN-Occlusal plane angle showed a great stability in 2 years after orthodontic treatment.
3. In this study it has likewise been shown that the changes in the inclination of the occlusal plane accompanied by treatment, have .a little tendency to return to the original condition in those case exhibiting or no growth.
4. Since I have observed many cases 2 years after treatment in which the tipped occlusal plane has remained tipped. The relapse occurred slightly, however, was not statistically significant.
