纯钛个性化正畸托槽的设计与制造技术研究
Research of design and manufacturing technology of titanium personalized orthodontic bracket
摘要
Abstract
Objective A titanium personalized orthodontic bracket is designed and manufactured using the technol-ogy of computed tomography (CT), computer aided design (CAD), finite element analysis (FEA), and selective laser melt-ing (SLM) to well match the patient tooth so as to realize mold-free manufacturing. Methods A model of a titanium personalized orthodontic bracket which is built by CT scanning machine and Pro/E software, is imported into Ansys soft-ware to carry out finite element simulation analysis with nonlinear contact method. Then, the titanium personalized orth-odontic bracket is proposed after the model data above is imported to SLM molding equipment via titanium powder melt-ed with layer by layer using a high-speed scanning galvanometer. Results The maximum equivalent stress of the titani-um personalized orthodontic bracket is distributed uniformly and reasonably, the titanium personalized orthodontic bracket formed by SLM molding equipment can provide high accuracy and there is a high similarity between the bottom of the orthodontic bracket and the tooth surface shape. Conclusion The combination of CT, CAD, FEA, SLM technolo-gy can fulfill model-free manufacturing of the personalized orthodontic bracket and thus shorten the manufacturing cycle.关键词
