摘　　要：目的对照研究新疆部分汉族、维吾尔族正常人群下颌后牙区解剖结构,为颌面外科手术提供测量方法和量化指标。方法 120例汉族、维吾尔族健康成年人拍摄曲面断层片,分别在曲面断层片上测量颏孔、颏孔远中1、23、cm处管嵴距、下颌骨高度及下颌角角度,然后对测得的数据作统计学处理。结果汉族、维吾尔族健康成年人下颌骨管嵴距在颏孔后1 cm处最大,维吾尔族:男性为(24.77±3.32)mm,女性为(23.78±2.30)mm;汉族:男性为:(22.97±2.68)mm;女性为(22.44±2.07)mm。颌骨高度在颏孔处最大,维吾尔族:男性为(39.18±2.46)mm,女性为(35.67±2.95)mm;汉族:男性为(37.94±2.30)mm,女性为(34.76±2.87)mm;下颌角角度,维吾尔族:男性为(105.36±6.03)°,女性为(119.24±6.60)°;汉族:男性为(118.10±7.78)°,女性为(126.20±4.56)°。结论健康汉族、维吾尔族成人男、女性下颌管管嵴距、下颌骨度度及下颌角角度均有明显差异,在进行口腔种植及颌面外科手术时应该考虑民族间颌面部解剖差异。Objective To measure the data of the distance from the crest of the ridge to the superior aspect of the mandibular（CAN） canal and investigate the difference of the data between the Han nationality and Uigur,and provide referrible data for the implantodontics and dentofacial surgery in Sinkiang territory.Methods The panoramic radiographs were imaged in 120 cases.And then CAN selected distances posterior to the mental foramen were recorded,the values were transformed into actual length according to arith formula and analyzed statistically.Results All statistic data indicate that CAN of 1cm posterior to the mental foramen were the longest in two races.CAN of Uigur male at 2 cm posterior to the mental foramen were longer than that of Han（P0.01）.There is no difference statistically in other part.Conclusions Dentist will probably take into account with the differences between two races in osteotomy and implantation.
