目的研究个体化钛修复体结合自体松质骨移植,修复人下颌骨节段性缺损的效果。方法术前在CT扫描并三维重建基础上,应用计算机辅助制造技术制作个体化钛修复体,为5例下颌骨节段性缺损进行了个体化钛修复体下颌骨重建手术,观察并评价其修复效果。结果所有手术均按照术前设计一次成功完成个体化钛修复体植入,术创全部一期愈合,下颌骨外形恢复良好,咬合关系正常,总体效果满意。结论基于CT与计算机数字化处理辅助制作的个体化钛修复体植入术,避免了自体骨移植带来的创伤和损失,可修复下颌骨较大的骨缺损,外形恢复佳。
Objective To study the effect of individual titanium prosthesis combined with autologous cancellous bone graft in repairing segmental mandibular defect. Methods Preoperative CT scan and three-dimensional reconstruction based on the use of computer-aided manufacturing technology to make individual titanium prosthesis for segmental mandibular segmental defect in 5 cases of titanium reconstruction mandibular reconstruction surgery to observe and evaluate the repair effect . Results All the operations were successfully completed in accordance with the preoperative design of a personalized titanium prosthesis implantation, all the first operation of healing, mandibular shape recovery is good, the occlusion relationship is normal, the overall effect is satisfactory. Conclusion Based on CT and computerized digitalized aided titanium prosthesis implantation, the trauma and loss caused by autologous bone graft are avoided, and the larger bone defect in mandible can be repaired.
