摘要
目的:利用Cerec椅旁计算机辅助设计与制造(computer aided design and manufacture,CAD/CAM)与功能牙合道(functionally generated path,FGP)技术修复1例二氧化锆全冠,比较计算机在虚拟牙合架、生物再造、FGP技术下设计面的差异。方法:将16行标准牙体预备后,Cerec 4.4扫描预备体、对牙及咬合状态,并扫描制取的印模(FGP),在数字化设计中对上述3种模式进行设计,生成3种不同的咬合面。设计FGP二氧化锆全冠后,导出并切削,完成临床试戴、粘接。结果:在CAD中生成的3种模式牙合面存在差异,FGP最佳,生物再造次之,虚拟架最差。FGP技术指导设计可少量调,获得稳定的关系。结论:在椅旁CAD/CAM二氧化锆全冠修复中,可推荐使用FGP技术消除干扰。
Objective： Combined with Cerec chair-side computer aided design and manufacture（ CAD/CAM）,to repair a case of zirconia full crown and find the differences among the biogeneric reconstruction,virtual articulator,and functionally generated path（ FGP） technics. Methods： After tooth preparation,Cerec 4. 4 software was used to scan the tooth,the occlusal state,and the impression（ FGP）. The three models were designed in the CAD / CAM. Different occlusal surfaces were created,zirconia full crown was milled by using chair-side CAM,tried in and bonded in clinic. Results： There were differences among the three models generated in CAD,but FGP was the best,followed by biological reconstruction,and the virtual model was the worst. FGP technic have made a small amount of clinical bite adjustment,and got a stable relationship. Conclusion： The best way to use CAD / CAM zirconia crowns in chairs-side to eliminate interference is using FGP technic.
