目的：探讨成人错牙合畸形的分类与牙槽骨垂直吸收间的关系。方法：选择来我院行正畸治疗的18岁以上患者450例，对治疗前的石膏模型及全颌曲面断层片的辅助检查进行统计，按不同错牙合畸形分类标准进行诊断分类，并对牙槽骨垂直吸收进行统计分析。结果：按安氏错牙合畸形和矢状骨面型分类后，牙槽骨垂直吸收的患病率无显著差异（P＞0．05）；按垂直骨面型（FH－MP平面）分类后，均角、低角和高角的垂直型牙槽骨吸收患病率分别为22．2％、41．2％和32．9％（P＜0．05），在两两比较中，低角和高角的垂直型牙槽骨吸收患病率均明显高于均角成年错牙合患者（P＜0．05），而低角与高角组间无统计学差异（P＞0．05）。结论：在成年错牙合患者中，异常的垂直骨面型与牙槽骨的垂直吸收有一定相关性，提示临床治疗中对具有垂直向不调的成年错牙合畸形患者，更应关注其牙周健康及定期进行牙周维护性治疗。

AIM:To investigate the relationship between different kinds of malocclusion and vertical alveo-lar resorption.METHODS:450 adult patients underwent orthodontic treatments were included.The malocclusion of the patients was examined and classified by orthopantomography and plaster cast,alveolar vertical resorption was meas-ured and compared among malocclusion types .RESULTS:No significant difference between the alveolar vertical re-sorption and different types of malocclusion was observed according to either Angle's diagnose system or sagittal skeletal diagnose system(P>0.05).According to the vertical skeletal diagnose system (FH-MP),vertical resorption in the patiens with average angle,low angle and the high angle were 22.2%,41.2%and 32.9%respectively.average angle vs low angle or high angle (P<0.05),low angle vs high angle (P>0.05).CONCLUSION:Different molar posi-tion and sagittal position of maxillary and mandible may not affect the vertical alveolar resorption rate.But the vertical position of maxillary and mandible may affect the vertical alveolar resorption.
