摘　　要：目的:使用有限元方法进行个性化种植体分析,为医师选择适合的种植体形态提供参考依据。方法:通过自行开发的口腔虚拟种植系统重建患者颌骨模型,并选择相应种植体进行虚拟种植以模拟各颌牙缺损状态下种植体植入的位置及方向,利用FEA分析咀嚼运动中不同种植体产生的应力分布,同时进行力学性能评价。结果:实现了口腔种植体的个性化选择方案。结论:所提出的口腔种植力学性能评价方法,能够从应力角度为医师选择种植体形态提供参考依据。Objective： To provide dentist with principles for implant selection based on finite element analysi（FEA）. Methods：The jaw bone was reconstructed by using an oral virtual dental implant system. Implants were chosen based on this model. They were implanted virtually simulating the implants＇ position and orientation in different edentulous conditions. The stress distribution of different implants in chewing process was analyzed by FEA, and mechanical properties were evaluated. Results ： The dental implants with optimal length and diameter were chosen with FEA analysis. Conclusion： FEA analysis can provide help for physicians to select personalized dental im- plants.
