摘　　要：目的:利用CAD/CAM以及3D打印技术体外辅助游离腓骨瓣重建上颌骨半侧缺损。方法:利用CAD/CAM建立游离腓骨瓣重建上颌骨半侧缺损的三维模型,设计个性化重建板、截骨导板辅助重建完成,通过3D打印技术生成术前模型、截骨导板以及重建板,模型外科模拟手术。采用SPSS18.0软件包对数据进行统计学分析。结果:快速建立了3段式游离腓骨重建上颌骨缺损的数字化模型,并设计生成原发灶截骨导板和重建辅助个性化重建板。定点测量显示,模型外科模拟重建精度与计算机模拟无显著差异(P>0.05)。结论:优化设计的辅助措施和个性化重建板可以增加游离腓骨重建上颌骨缺损的准确性,有助于临床上精确外科重建。PURPOSE： To optimize reconstruction of maxillary unilateral defect by free fibula flap rapidly through 3 D printing technique. METHODS： 3 D models of reconstruction of unilateral maxillary defect by free fibula flap was established via CAD/CAM, metal customized plates and resin osteotomy guides were designed and manufactured via 3 D printing technique, simulating operation was performed on models in vitro, and reconstructive accuracy after surgical simulation was analyzed using SPSS 18.0 software package. RESULTS： Digital models involving reconstructive bone and affiliated devices（plates and guides） were established and fabricated rapidly. There was no significant difference between simulating point on computer and surgical simulating point in vitro. CONCLUSIONS： The optimized design and customized plate can increase the accuracy of reconstruction of maxillary defects with free fibula in vitro, which is helpful for accurate surgical reconstruction.
