THE EPIDEMIOLOGIC STUDY ON DENTAL MALOCCLUSION AND SKELETAL FACIAL PATTERN

The study was designed to examinate the discrimination rate of 4 antero-posterior cephalometric measurements from Angle´s malocclusion groups. The material was 246 cephalometric radiographs taken from 42 Normal occlusions, 83 Class I malocclusions, 64 Class II Division I malocclusions, 57 Class III malocclusions. ANB angle, APDI, AB/OP angle, and Wits appraisal as measurements of antero-posterior skeletal relationship were measured on the cephalometric radiographs and statistically analyzed by the Canonical Discriminant Function. The results of this study were as follows 1. ANB angle, APDI, AB/OP angle, and Wits appraisal were clinically useful measurements for the evaluation of the antero-posterior skeletal relationship 2. The rates that discriminate actual malocclusion groups were 77.45% in Wits appraisal, 74.02% in AB/OP angle, 71.08% in ANB angle, and 70.59% in APDl. 3. The discrimination rate of actual Class III malocclusion show above 93%, but actual Class I and Class II division I malocclusions were relatively low.
