牙种植定位导向模板的计算机辅助设计和制作
Computer aided design and computer aided manufacture of templates in dental implantation
摘要
Abstract
BACKGROUND: Currently, the templates widely used in implant surgery in China were prepared on plaster model. As the three-dimensional structure of the jaw is unclear, accurate implanting is difficult and complications of implantation are prone to exist.OBJECTIVE: To prepare oral implant templates with CT and computer aided design (CAD)/computer aided manufacture (CAM) in order to locate implants in the right position and direction.METHODS: Plaster models of maxillary edentulous with location marker were scanned with CT. The MIMICS software was used to reconstruct three-dimensional model and simulate implantation. Simulated implant was located in the ideal position based on the anatomical structure of the implanted jaw and the implanted methods according to prosthetic and aesthetic requests. The information of position angle of the simulated implant was transferred to the template while it was prepared. The data were input rapid prototyping equipment to prepare resin template. The accuracy of the template was tested after implantation in it.RESULTS AND CONCLUSION: The top deviation of the implant was (0.87±0.21) mm and the bottom deviation was (0.82± 0.16) mm after implantation. The deviation of the implant in the vertical direction was slightly bigger than those in the buccolingual direction and mesiodistal direction. The implant design can be accurately transferred to the template before operation.Implantation can be well guided using this, and it can improve the safety, accuracy and the successful rate.关键词
