9. Differential diagnosis of Class III malocclusions 3
|
Results of the study 2
The cephalograms taken at the three time points were used to make linear and angular measurements for comparison between Group N and Group R.
First, linear measurements at the three time points (initial examination, appliance removal, and occlusal stability) were made. The results are shown below.
|
|
No significant difference was noted in any of the linear cephalometric measurements between the two groups.
Next, angular measurements were made for comparison between the groups.
|
|
There were significant differences in ANB, L1 inclination, AO-BO, A-B plane angle and gonial angle.
|
|
Particularly, AO-BO and gonial angle showed significant differences both at initial examination and at occlusal stability. Furthermore, significant differences in A-B to Mand. and ODI were observed between the two groups at all the three time points.
