控制钛的氧化行为对钛-瓷结合力的影响

The effects of controlling oxidation of titanium on the bonding strength of titanium and porcelain

钛在口腔修复领域中的应用越来越多,但其作为烤瓷冠桥修复的金属基底材料,仍存在着钛-瓷结合不理想的问题,限制了其在临床的应用。钛的氧化行为是影响钛-瓷结合力的主要因素,控制钛在高温时的氧化反应是决定钛-瓷修复成败的重要因素。本文就钛-瓷中间层的引入、钛的预氧化处理和钛的辅助气体保护行为对钛-瓷结合力的影响作一综述。

Use of titanium in dentistry and medicine has increased in recent decades. Although porcelain fused to a metal crown is usually used as a technique for dental restorations, titanium＇s insufficient bond strength with porcelain yields inferior dental applications. The oxide layer produced on titanium was considered to have a potentially adverse effect on titanium-porcelain bonding. This article reviews studies published recently on the effects of oxidation of titanium on the bonding strength of titanium and porcelain.
