目的：比较不同垂直骨面型下前牙区牙槽骨形态特征，并初步探讨年龄对牙槽骨形态的影响。方法选取未行正畸治疗的100例患者的CBCT资料，根据患者垂直骨面型进行分组，组内再根据年龄分为青年组及中年组。应用Simplant软件进行下切牙区牙槽骨形态分析，并使用SPSS软件进行数据处理。比较各类骨面型下前牙区骨形态以及年龄对牙槽骨形态的影响。结果下切牙区牙槽骨形态及下切牙倾斜度在不同垂直骨面型间存在统计学差异，增龄也会对牙槽骨形态造成影响。高角组的唇舌侧牙槽骨高度较低，骨厚度较小，下切牙较舌倾。结论不同垂直骨面型之间下切牙区牙槽骨形态存在差异，提醒在正畸矫治设计时予以注意。

Objective To investigate the correlation between the morphology of the mandibular tooth-alveolar complex and vertical facial types. Methods The selected CBCT archives from 100 cases without orthodontic treatment were divided into three groups based on the vertical facial types ( FH-MP, SN-MP, FHI ) . The measurements of the morphology indexes of the lower incisor region were conducted with Simplant. The alveolar morphology was compared among the three groups and between different ages. The data were statistically analyzed. Results There were significant differences in the alveolar morphology and the inclination of the lower incisors among the three groups. Compared with the hypo-divergent group, the hyper-divergent group had a lower alveolar bone height,less bone thickness at the root apex level and more inclined lower incisors. Furthermore, the middle-aged group had a less thickness and height of bone than the young group. Conclusion The morphology of the mandibular tooth-alveolar complex varies with the vertical facial pattern, which is an influential factor in orthodontic treatment planning and assessment of treatment outcome.
