种植导航模板的计算机辅助设计和制造

目的：采用计算机辅助设计和制造技术制作种植导航模板,以确保种植体植入的安全性,获得理想的植入位置和方向。方法：应用牙科CT扫描患者上下颌牙弓,并转换成三维模型;取模并翻制牙颌石膏模型,测量牙颌石膏模型表面三维数据,获得点云数据文件,并转换成三维模型,并与CT获得的三维模型配准。按照种植体植入标准和要求计算机辅助设计种植导航模板,利用数控激光快速成型技术制作模板。结果：完成的计算机辅助设计和制造的种植导航模板实物质量稳定,精度较高。结论：种植导航模板能在术前确定种植位置以及方向,术中具有导航作用,具有一定的应用前景。

Computer aided design and manufacture of individual implant Plate

Objective：To ensure the safety as well as ideal location and direction of dental implant through navigative implant template by computer-aided design and manufacture.Methods：Dental CT scan with maxillar and mandibular arch was converted into three-dimensional model.Plaster model of patients＇ denture was also converted into three-dimensional model by three-dimensional optical measuring method.Then,the two three-dimensional model were assembled.In accordance with the standards and requirements of dental implants,navigative implant template completed by computer-aided design cultivation,and laser rapid prototyping techniques.Results：Completed navigative implant template by computer-aided design and manufacture attained physical stability and high accuracy.Conclusion：Navigative implant template could determine the direction and place of implant before operation and play an role of navigation in implant surgery,which shows prospective talent in clinical application.
