摘　　要：目的:开发口腔修复CAD/CAM系统中标准牙冠和桥体数据库原型系统,帮助口腔医生快速获得牙冠设计的数据模板,为高效地设计牙冠模型作准备。方法:首先,利用AtosⅡ激光测量设备,采集28颗标准冠/桥石膏模型(1∶1)的三维数据;然后,采用细分曲面逼近的方法重构标准冠/桥的数据模型;最后,设计标准冠/桥数据库的多层数据存储和管理结构,采用VC++6.0和Hoops图形库开发了标准冠/桥数据库系统原型。结果:标准冠/桥体数据库原型系统的构建符合设计要求,能够作为后续牙冠设计的数据模板。结论:所建立的标准冠/桥数据库高效、精确、可靠,可用于开发国产口腔修复CAD/CAM系统。Objective To establish the standard tooth crowns and bridges datahase in CAD/CAM system and help the doctor rapidly design the shape of teoth crown according to model data template from the database. Methods Firstly,the 3D data of 28 standard tooth crowns and bridges were measured by Atos Ⅱ equipment. Secondly,the method of the subdivision surface tilting to the points was adopted to reconstruct tooth model. Finally, the multilayer database structure was designed and the software prototype was developed using VC ＋ ＋ 6.0 and Hoops graphites library. Result The establishment of the standard crowns and bridges database met the designing requirement and provided the data template for designing the tooth crown. Conclusion The method of establishing the standard tooth crowns and bridges database is feasible and efficient,which provides basis for dental CAD/CAM system.
