计算机辅助设计与制作钛支架在无牙颌患者种植固定修复中的应用现状

Application of computer-aided design and computer-aided manufacturing of milled titanium framework in the implant-support rehabilitation of edentulous patients

计算机辅助设计与制作(CAD/CAM)系统应用于种植修复已有多年历史,其快速发展和不断完善为口腔种植修复治疗提供越来越广泛的服务。CAD/CAM切削全牙列钛支架相比铸造支架,精密度高,密合性好,就位良好,节省椅旁时间并简化操作步骤。本文就CAD/CAM钛支架制作过程以及近期内在无牙颌患者种植固定修复的应用作一综述。

Computer-aided design and computer-aided manufacturing（CAD/CAM） has been widely used in implantology for a long time. The rapid development and improvement of such method have broadened the scope of prosthetic implant treatments and brought profound changes to the implantology industry. Compared with casting alloy framework, CAD/ CAM milled titanium framework has the advantages of precision, aesthetics and passive fit, time efficiency, and simplicity of procedure. The application of CAD/CAM milled titanium framework in the implant-supported fixed rehabilitation of edentulous patients was reviewed.
