title: The effects of overjet on dentoalveolar compensation.
abstract: The purpose of this study was to investigate the relationship between overjet and dentoalveolar compensation in different overjet patterns. The lateral cephalometric head films of 80 untreated subjects (40 males and 40 females) aged 13-15 years were divided into four groups based on a normal, edge-to-edge, negative, or positive overjet. Seven linear and eight angular cephalometric measurements were used to assess dentoalveolar compensation in the different overjet patterns, and the differences between the groups and between genders were assessed by means of analysis of variance and the least significant difference (LSD) test. In addition, correlation coefficients between overjet and other variables were calculated. The results showed that there were statistically significant differences in measurements of MxAABH (mm), MxPABH (mm), and angles 1-NA, 1-1, 1-SN, 1-SN, 1-MP, and SN-AB among the overjet groups. In addition, significant correlation coefficients were found between overjet and MxAABH (mm), 1-NA (mm), and angles 1-1, 1-SN, 1-SN, 1-MP, and SN-AB. The evaluation of dentoalveolar compensation in different overjet patterns may be useful in treatment planning and treatment success.
