摘　　要：目的术前模拟游离腓骨瓣重建上颌骨半侧缺损,快速生成个性化重建辅助方案,并分析其可行性。方法以1名健康男性志愿者的薄层CT为源数据样本,利用Mimics软件建立游离腓骨瓣重建上颌骨半侧缺损的三维模型,对不同分段设计的腓骨重建上颌骨半侧缺损进行术前模拟和分析;利用3-matic软件包设计生成个性化重建板,并且模拟最终修复。结果本研究精确建立了3种(2段式、3段式和4段式)游离腓骨重建上颌骨半侧缺损模型,其所需腓骨的总长度分别约为6 mm、8 mm以及12 mm;并且本研究快速设计了个性化重建板以及模拟了后期种植修复。结论数字化模拟可以快速地建立游离腓骨重建上颌骨半侧缺损的可视化方案,为进一步精确辅助术者设计生成重建板和定位导板奠定基础。Objective To analyze the feasibility of digitally simulating the maxillary unilateral defect reconstructed by free fibula flap.Methods A thin slice CT of a healthy male volunteer was used as the data source in this study.The 3D models for reconstruction of unilateral maxillary defect by three kinds of designed segments of fibula(2-segment,3-segment and 4-segment)were established.And feasibilities of three reconstrucive stratgeries were analyzed properatively.Futhermore,customized plates,implants,zygomatic implants and upper structures of the three stratgeries were simulated.Results In this study reconstructions by 2-segment,3-segment and 4-segment fibula flap were simulated accurately and the length of fibula for reconstruction was 6 mm,8 mm and 12 mm respectively.Moreover,customized plates,dental implants,upper structure were simulated preoperativly and rapidly.Conclusion Visual strategeries of maxillary reconstruction by free fibula flap can be established rapidly via digital simulation preoperatively and individually,and it supply data fundation for further digital subsidiary steps.
