摘要
目的应用牙CT对牙槽突裂植骨术后的骨桥位置进行定位分析。方法选取18名单侧完全性牙槽突裂患者,在牙槽突裂植骨术后3个月对植骨部位进行牙三维CT扫描,将牙槽突裂隙分割后对植入骨进行定位。结果牙槽突裂植骨术后,近远中向上骨桥的数量没有统计学差异(P>0.05);唇腭向上唇侧的骨桥数多于腭侧骨桥数(P<0.001);垂直向上,植入骨的骨桥主要存在于裂隙侧中切牙的根中和根尖1/3,而鼻底及近牙槽嵴顶的骨桥数量较少(P<0.05)。结论牙槽突裂植骨术后骨桥的位置主要位于裂隙侧中切牙的根中和根尖1/3处,且唇侧的骨量明显多于腭侧的骨量。
Objective To evaluate the outcome of alveolar cleft bone grafting using dental 3D-CT, and identify the position of the bone bridge. Methods Eighteen unilateral complete alveolar cleft patients were chosen in this study and using dental 3D-CT to evaluate the position of the bone bridge after three month bone graft. The alveolar cleft was divided at several section, the bone bridge position were checked, and the position of graft bone bridge were calculated. Results In mesial and distal direction, there was no difference between mesial and distal bone bridge（P0.05）. In labial and palatal direction, labial bone bridge was more than palatal bone bridge（P0.001）. In vertial direction, bone bridge which at one third of apical root and middle root of the central incisor root, was more than bone bridge which at alveolar crest and nasal base. Conclusion After secondary alveolar bone graft, bone bridge in alveolar cleft position is most located at labial and apical third and middle third of the central incisor root.
