Abstract

The development of titanium–porcelain prosthetics has garnered significant attention due to their excellent biocompatibility and aesthetics. Unfortunately, the application of titanium–porcelain prosthetics has been restricted by their poor bonding strength. In this study, to enhance the bonding strength of the titanium surface, a ceramic coating was synthesized on the titanium surface using the micro arc oxidation method. Furthermore, the ceramic coating can substitute body porcelain in titanium–porcelain prostheses due to its color similarity to natural teeth. The morphologies and phase compositions of the coatings were analyzed using SEM and XRD techniques. The bonding strength, wettability, and colors were also investigated. The results show that the corresponding bonding strength between the titanium substrate and ceramic coating is higher than 30 MPa, which meets the requirements of porcelain-fused-to-metal restorations. The concentration of cerium oxide can be modulated by adjusting the cerium nitrate coating’s color distribution. Therefore, this method offers a practical and valuable approach to replacing opaque and body porcelain with ceramic coatings.

钛表面微弧氧化膜替代不透明瓷和体瓷的研制

钛瓷修复体因其良好的生物相容性和美观性而备受关注。但钛瓷修复体的结合强度较差，限制了其应用。为了增强钛表面的结合强度，本研究采用微弧氧化法在钛表面合成了陶瓷涂层。此外，由于钛瓷涂层与天然牙的颜色相似，可以替代钛瓷修复体瓷。采用扫描电镜（SEM）和x射线衍射（XRD）分析了涂层的形貌和相组成。研究了胶合强度、润湿性和颜色。结果表明：钛基材与陶瓷涂层相对应的结合强度大于30 MPa，满足瓷熔金属修复的要求。通过调整硝酸铈涂层的颜色分布，可以调节氧化铈的浓度。因此，该方法为用陶瓷涂层代替不透明瓷和体瓷提供了一种实用而有价值的方法。
