背景:金瓷修复体具有效果美观及组织相容性好、强度高等优点.目的:综述近几年来不同表面处理技术提高金瓷结合强度的成果.方法:应用计算机检索CNKI数据库、OVID数据库有关提高修复体金瓷结合强度的相关文章,英文关键词为"bondstrength of porcelain,PFM,surface treatment technology,preoxidation,sol-gel,plasma-spray";中文关键词为"金瓷结合,金属烤瓷全冠,表面处理,预氧化,溶胶凝胶,等离子".结果与结论:金瓷结合强度是修复体成功应用的主要方面.利用适当的金属表面处理技术改善瓷与合金的结合强度,可以达到更完美的修复效果.预氧化工艺、深冷处理、溅射喷金技术、等离子喷涂技术、溶胶凝胶技术、纳米过渡性介质技术、真空镀膜技术等几种表面处理技术都不同程度的地提高了金瓷结合强度,但有些技术尚在不断完善中,等待广大学者进一步继续研究.%BACKGROUND: Porcelain-fused-to-metal restoration is aesthetic, good organization compatibility and high strength, which is favored with the majority of patients.OBJECTIVE: To review the results of the improvement of the bond strength of porcelain-fused-to-metal with different surface treatment technologies in recently years.METHODS: A compute-based online retrieval of CNKI and OVID databases was performed for articles concerning the improvement of the bond strength of porcelain-fused-to-metal. The key words were "bond strength of porcelain, PFM, surface treatment technology, preoxidation, sol-gel, plasma-spray" in English, and "porcelain, PFM, surface treatment, preoxidation, sol-gel, plasma-spray" in Chinese.RESULTS AND CONCLUSION: The bond strength of porcelain-fused-to-metal is a key factor of successful application for restoration. Suitable use of surface treatment technology can improve the bond strength of porcelain-fused-to-metal, which could have a better repairing effect, such as: preoxidation, crytreat, sputtering Au intemadiate technology, plasma spraying technology, sol-gel technology, nano-medium material and vacuum deposition technology. These surface treatment technologies have improved the bond strength of porcelain-fused-to-metal at different degrees, but some technologies are still in the development and need to be further researched.
