摘要
目的 观测国人的下颌前牙牙槽窝底到下颌骨下缘垂直距离的数据。方法 取100具成人下颌骨,由前牙唇侧壁测量其牙槽窝底到下颌骨下缘的垂直距离。结果 中切牙牙槽窝底到下颌骨下缘的垂直距离平均为(26.19±5.64)mm:侧切牙牙槽窝底到下颌骨下缘的垂直距离平均为(23.95±6.08)mm,尖牙牙槽窝底到下颌骨下缘的垂直距离平均为(20.58±5.26)mm。结论该数据为解剖学增添资料,也为颏部的表面划线提供应有的数据。
Objective To study the vertical distance between alveoli fossa of mandible anterior teeth and lower margin of mandible in Chinese people. Methods The vertical distance between alveoli fossa and lower margin of mandible from labial lateral side were measured in 100 adults. Results The average vertical distance from alveoli fossa in central incisor, lateral incisor and canine teeth to lower margin of mandible were ( 26.19±5.64)mm,(23.95±6.08)mm and (20.58±5.26)mm respectively. Conclusion The data add new material for anatomy and provide the essential reference to draw the surface line of chin as well.
