摘　　要：目的:研究汉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 :6 0例汉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、2、3cm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处理。 结果:健康成年人下颌骨管嵴距在颏孔远中 1cm处最大 ,男性为(2 3.78± 2 .30 ) m m,女性为 (2 2 .4 4± 2 .0 7) m m。颌骨高度在颏孔处最大 ,男性为 (37.94± 2 .30 ) m m,女性为 (34.76± 2 .87) m m。下颌角角度男性为 118.10°± 7.78°,女性为 12 6 .2 0°± 4 .5 6°。结论Abstact: Objective: To study the anatomic structure of mandible in healty Han nationality and provide quantification to surgery. Methods: The panoramic radiographs were imaged for people aged from 20 to 35 whose peridentium were healhy(the male 30 and the female 30 respectively in Han nationality in Xinjiang). And CAN at and selected distances posterior to the mental foramen were recorded, the values were transformed into actual length according to arith formula and analyzed statistically. Results: CAN of 1 cm posterior to the mental foramen were the longest in Han nationality youths, male was (23.78±2.30)mm and female was (22.44±2.07)mm. (P<0.01). Height of mandible at mental foramen was longest, male was (37.94±2.30)mm and female was (34.76±2.87)mm (P< 0.01). Mandible angle in male was 118.10°±7.78°,female 126.20°±4.56°. Conclusion: The panoramic radiographs can provide quantification of CAN and height and angle of mandible to surgery.
