Abstract:
This study was undertaken to find out the factor highly correlated to the depth of overbite among the skeletal factors of the franiofacial complex using lateral roentgenocephalograms. The subjects cconsited of fifty normal occlusions, sixty Class I malocclusions, sixty Class II division 1 malocclustions and sixty Class III malocclusion. The results were as follows, 1. Ans-Go-Me angle and lower gonial angle showed high correlation to the depth of overbite in the total malocclusion sample. 2. The mean values of Ans-Go-Me angle and lower goinal angle for the normal sample were 49.8degrees and 75.6degrees , respectively. 3. Ans-G0-Me angle above 56degrees or lower gonial angle above 84degrees indicated a tendency toward an openbite Conversely, Ans-Go-Me angle below 48degrees or lower goinal angle below 73degrees indicated a tendency toward a deepbite.
