摘要/Abstract

摘要： 目的探讨预防Cercon氧化锆全瓷冠桥返工的预防方法。方法通过我院2 238例Cercon全瓷氧化锆冠桥的制作，氧化锆全瓷冠桥制作后出现的返工进行回顾，并进行原因分析和总结。结果 2 238例患者进行了18个月到5年的质量调查，出现返工共98例,返工率4.37%，其中内冠冠桥断裂原因返工29例，单冠断裂返工10例，崩瓷原因返工39例，由于适合性的原因返工10例，因患者要求改变颜色和形态等原因返工10例。结论氧化锆修复过程中的每一步要严格遵循基牙形态设计原则，细致地进行临床操作及技工制作以及合适的适应证选择，可提高修复的成功率。

Abstract: Objective To explore the methods to prevent Cercon Zirconia crown and bridge rework. Methods The production of 2 238 cases cercon all-ceramic zirconia crowns and bridges in my hospital was reviewed. Reasons for rework were analyzed and summarized. Results 2238 cases of patients were observed from 18 months to 5 years to investigate the quality of crowns and bridges production. 98 cases were reworked in total with the rework rate of 4.37%, among which 29 cases were for inner crown fracture, 10 cases for single crown fracture, 39 cases for porcelain collapse, 10 cases for poor fitness and 10 cases for poor color match and poor morphology. Conclusions Zirconia restorations depend on common effort of every step:strictly following Principles of tooth preparation, a detailed clinical operations, meticulous laboratory production and selecting appropriate indications.
