All-ceramics have been widely used in dentistry. The favorable mechanical properties and high biocompatibility of zirconia ceramics lead to using it as an alternative to the conventional porcelain-fused-to-metal (PFM) restorations. However, its major limitation is the difficulty of achieving proper bonding due to the chemical inertness of its surface. The current work aims to show the application of the zirconia in dental fields and to discuss the various surface treatment options available. Hydrofluoric acid treatment of the zirconia surface did not result in durable bonding. A combination of mechanical and chemical preparation is essential to reach an activated surface. Different mechanical preparation methods were used as airborne-particle abrasion, tribo-chemical silica coating, low-fusion porcelain layers application, selective infiltration etching, laser irradiation, plasma spraying and zirconia ceramic powder coating. Chemical preparation involves the use of silane and primers. However, the proper universal bonding technique of zirconia has yet to be established, owing to insufficient supporting evidence in literature. This review highlights the use of zirconia ceramics in dental field and its proper bonding protocol achieved via different surface treatments.
全陶瓷材料在牙科领域已得到广泛应用。氧化锆陶瓷良好的机械性能和高生物相容性使其成为传统烤瓷熔附金属（PFM）修复体的替代材料。然而，其主要局限性在于，由于其表面化学惰性，难以实现良好的粘结。当前的工作旨在展示氧化锆在牙科领域的应用，并讨论现有的各种表面处理方法。对氧化锆表面进行氢氟酸处理并不能产生持久的粘结效果。机械和化学预处理相结合对于获得活化表面至关重要。不同的机械预处理方法包括空气颗粒研磨、摩擦化学硅涂层、应用低熔瓷层、选择性渗透蚀刻、激光照射、等离子喷涂和氧化锆陶瓷粉末涂层。化学预处理涉及使用硅烷和底漆。然而，由于文献中缺乏足够的支持证据，尚未建立适用于氧化锆的通用粘结技术。本综述重点介绍了氧化锆陶瓷在牙科领域的应用以及通过不同表面处理实现的适当粘结方案。
