摘要
目的:测量上颌末端牙槽骨相关数据,为此区人工种植牙种植提供参考依据。方法:用颌面专用锥束CT测量50名志愿者:男性26例(16-74岁);女性24例(19-78岁)上颌末端牙槽骨6个标志点,四条线距的长度。结果:离上颌窦最近处牙槽骨的高度:9.08±4.37mm;上颌末端牙槽骨的长度:16.13±5.76mm;上颌牙槽骨最末端点与上颌窦的距离: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性。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性,但不同性别的数值差异有显著性,男、女分别为:8.92±2.54mm、7.11±2.67mm。结论:研究结果初步为在上颌末端牙槽骨进行种植提供了依据,为种植体数目及确定其相对位置与方向提供参考。
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 soft-ware 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： DE, the height of the maxillary alveolar bone which was nearest to maxillary sinus, was 9.08 ± 4.37mm, AF. The length of the maxillary distal alveolar bone, was 16.13 ± 5.76mm, AC, the distance of maxillary distal alveolar bone endpoint to maxillary sinus was 14.32 ± 4.87mm. 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 of pterygomaxillary junction were 8.92 ± 2.54mm in male and 7.11 ± 2.67mm in female. There were no significant differences（P〉 0.05） on different side but had significant differences （P〈0.01 = in different gender of volunteer. Conclusion： 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.
