Abstract
The purpose of this study was to investigate the factors which cause the differences in the percentage of anterior overbite in spite of normal molar relationship in terms of skeletal, dental and dentoalveolar relations. The models and cephalograms taken from 154 subjects, 89 of shallow overbite and 65 of deep overbite ranging from 18 to 29 years of age were studied and analyzed statistically. The results were as follows. 1. In determining the percentage of anterior overbite, the significant differences were higher in the dental and dentoalveolar factors than in the skeletal factors and were higher in the proportional and angular measurements than in linear measurements. 2. The factor which had the greatest influence on the percentage of anterior overbite was the proportional parts of the dental and dentoalveolar heights. 3. The most influencing factor which determined the percentage of anterior overbite was the SN-MP angle among the skeletal factors.
