[Investigation of the functional treatment effects of the skeletal and dental Class III anomalies on the skeletal region].
This study was carried out on two groups with skeletal and dental Class III malocclusion. There were 21 patients in the first group (10 females and 11 males) on which the chin-cap treatment was performed and average age of these was 11 years and mean treatment period was 0.7 years. The second group which consisted of 9 individuals was the control group and none of them had any orthodontic treatment. The control group consisted of 5 females and 4 males individuals and average age was 9.7 years and mean control period was 2 years. This investigation was performed on 60 cephalometric films obtained from both groups. 6 angular, 5 dimensional total 11 skeletal cephalometric measurements were performed on these films. When these groups were compared according to these measurements it was found that there was a decrease in SNB, SN/ANS-PNS angles also a decrease was detected in distances between Pg-Ramus Inferior tangent point, Pg-Ramus Superior tangent point, Cd-Pg points. On the other hand there was an increase in ANB angle and Wits appraisal which is the dimensional expression of ANB angle.
