The effects of overbite on the maxillary and mandibular morphology.

The aim of this study was to investigate the differences in the maxillary and mandibular morphology related to the overbite. A total of 80 untreated subjects were divided into 4 groups with normal overbite, edge-to-edge bite, open bite, or deep bite and were compared with one another. Differences between the overbite groups and between genders were assessed by means of variance analysis and the least significant difference test. In addition, correlation coefficients between the overbite and other variables were calculated. The results showed that there are statistically significant differences in the maxillary and mandibular morphology among the overbite groups.
