【摘要】 目的:探讨金属烤瓷修复体的修复效果,总结成功及失败的经验教训,提高口腔修复水平,为临床应用提供参考。方法:84例门诊患者,经金属烤瓷冠修复治疗0.5～7年,共计488个金属烤瓷冠,通过为期6个月的回访复查,采用美国加利福尼亚科学会的质量评价体系对金属烤瓷固定修复体进行临床效果评价。结果:84例患者488个金属烤瓷冠修复体中固位满意率为97.3%,边缘完整性满意率为94.6%,牙周健康满意率为95.2%,表面和颜色满意率为97.9%;活髓基牙牙髓病变率为10.25%;金属烤瓷修复体按不同时间段观察修复效果,发现各项指标的满意率在不同时间段比较无统计学差异;活髓基牙与无髓基牙的临床修复效果比较也未见统计学差异。结论:金属烤瓷冠修复仍是目前理想的固定修复方法,但在病例选择、修复体设计与制作、基牙的处理以及修复体的选色与配色方面,必须遵循相应的原则与方法,才能保证其满意的临床效果。更多还原

【Abstract】 Objective: To observe the clinical therapy effects of the porcelain-fused-to-metal (PFM) prosthesis and to summarize the experience and lessons from success and failure. Methods: 488 restorations made by metal porcelain complete crown or fixed-bridge selected from 84 cases which have received this therapy after 0.5 to 7 years were followed up for 6 months. The clinical effects of these subjects were assessed by the California Dental Association(CDA) quality assessment evaluation system. Results: It showed that the satisfactory rates of the retention , marginal integrity, periodontal health, surface and color of the crowns were97.3%,94.6%,95.2%, 97.9% respectively, and the rate of the vital abutment teeth with pulpitis was 10.25%. we had observed above had no significant differences in the different times after the restoration. The indications between the vital and pulpless abutment teeth had no significant differences also. Conclusion: PFM prosthesis is still the ideal method in the fixed prostheses. But the restoration principles must be followed during the case selection, prosthesis design and making, abutment preparation, shade match in order to have a satisfactory clinical result.更多还原
