摘要
目的:建立下颌固定义齿的三维有限元模型。方法:选择带有牙根的下颌固定义齿模型进行三维激光扫描,获得表面三维点云数据,经过软件处理形成三维有限元模型。结果:所建立的下颌固定桥模型仿真效果好、精确度高,基本满足了口颌系统中力学分析的需要。结论:利用三维激光扫描技术可以快捷、准确地建立三维几何模型和有限元模型,以满足临床工作的需要。
Objective： To construct three - dimensional finite element model of fixed partial denture. Methods： We selected a mandibular three - unit fixed partial denture model with abutment roots to undergo three - dimensional laser scanning and get point cloud data. After the data were processed by related software, a three - dimensional finite elemental model was constructed. Results： The emulational model was accurate. It could meet the need of dynamic analysis in stomatognathic system. Condusion： Laser scanning technic can generate three- dimensional finite elemental model quickly and exactly.
