| 摘 要： | 目的:探讨颅颌快速原型制作在颅颌面畸形牵引成骨治疗中应用的方法及其临床意义。方法:对16例平均年龄16.8岁的下颌骨畸形病例,应用计算机辅助设计制作颅颌三维原型,分析颌骨畸形的类型并在模型上进行个性化牵引成骨设计,选择牵引器及模拟牵引过程以指导实际手术操作。结果:16例均进行了术前模拟,术中按术前设计顺利进行了骨切开及牵引器的固定安置,所有16例病例术后牵引均达到了预期的目标,牵引长度15～23mm(平均18.5mm)。结论:通过计算机辅助的头颅三维原型制作及分析,可以大大增加牵引成骨的合理性及可靠性,有助于降低手术难度并获得良好的预期效果。

| Abstract: | Objective: To analyze the clinic value of 3D steorolithography model in distraction osteogenesis. Methods: 16 patients of maxillofacial deformities, with an average age of 16.8 years, were treated with distraction osteogenesis. CAD/CAM 3D rapid prototypies were made before operation for analysis of the deformities and to simulate guidance process of distraction. Results: Distractions were successfully performed in all 16 patients with an average length of 18.5 mm (15～23 mm). X-ray examination showed a perfect result as designed presurgically. Conclusion: 3D rapid prototyping can offer an ideal platform to simulate the treatment planning before distraction osteogenesis. A simulation on 3D model will simplified the operation process significantly. |
