摘　　要：目的探讨ANSYS程序和快速成型技术在下颌钛植入支架的设计与制作中的应用。方法利用正常人三维有限元模型,模拟一侧下颌骨体部缺损,建立个体化下颌钛植入支架三维有限元模型,通过图像处理及转换技术,指导快速成型设备加工成型。结果所建立的下颌钛植入支架三维有限元模型,具备个体化并与剩余下颌骨和原缺损下颌骨曲度相匹配;通过该模型,利用快速成型技术加工成功获得该支架的树脂模型。结论利用ANSYS程序和快速成型技术,对下颌钛植入支架进行设计和制作是完全可行的。Objective Discuss the application of the design and fabrication of mandibular titanium framework based on ANSYS and rapid prototyping. Methods Body defect was simulated on the right side of the normal hu- man mandible 3D finite element model. A whole 3D finite element model of the titanium framework was developed. Finally through image transformation technology, the model was fabricated by a rapid prototyping machine. Results A 3D finite element model of the individual mandibular titanium framework was developed, which was matched with the remaining mandible segment. And the resin model of the a mandibular framework was obtained by rapid prototyping. Conclusion Design and fabrication of mandibular titanium framework based on ANSYS and rapid prototyping is feasible.
