摘要
目的:测量上颌牙槽骨最末端相关数据,为此区种植手术提供参考依据。方法:用颌面专用锥束CT测量50名志愿者:男26人(16岁～74岁);女24人(19岁～78岁)上颌牙槽骨最末端3个标志点,两条线距的长度。结果:上颌牙槽骨最末端点与上颌窦的距离AC:14.32±4.87mm,以上各数据在志愿者左右两侧和不同性别间数值差异均无显著意义。上颌牙槽嵴最末端点到翼上颌联合的最下点的距离AB在受检者左右两侧差异均无显著意义,但不同性别的数值差异有显著意义,男、女分别为:(8.92±2.54)mm、(7.11±2.67)mm。结论:为术者在上颌末端牙槽骨进行种植的初步评估,为选择种植体及其数目、相对位置、方向提供参考。
Objective： To study the bone anatomic structure of the maxillary distale alveolar bone and provide reference for implant surgery in this region.Methods： cone beam 3D CT software quantitative measurements of the maxillary distale alveolar bone were performed in 50 volunteer：（26 from male with 16～74 age and 24 from female with 19～78 age）. Results： AC,the distance of maxillary distal alveolar bone endpoint to maxillary sinus was （14.32±4.87）mm. There were no significant differences （P〉 0.05）in meaning± standard deviation on different side and different gender of volunteer. The distance of AB, the maxillary distal alveolar bone endpoint to the lowest point ofpterygomaxillary junction were （8.92±9.54）mm in male and （7.11 ±2.67）mm in female. There were no significant differences （P〉0.05） on different side but had si^niflcant differences （P〈0.01） =in different gender of volunteer. Conclusions： Our study could evaluate the feasibility of implanting in the maxillary distal alveolar bone and provide references for the number of choices and relative position and orientation of implants.
