摘要:

背景:氧化锆陶瓷因具有良好的理化性能和生物相容性在口腔修复重建领域被广泛应用,但如何对氧化锆陶瓷表面进行改性,以提高修复体与牙体组织的粘接强度成为目前临床工作中的难点。
目的:综述口腔氧化锆陶瓷的粘接方法。
方法:应用计算机检索PubMed 数据库,检索关键词为“zirconia, silane coupling agent, resin cement, bonding”。
结果与结论:通过化学摩擦硅涂层系统结合新型混合非功能性硅烷偶联剂对氧化锆瓷进行表面处理,利用小粒径(50 µm)的含硅颗粒氧化铝粉末对氧化锆进行喷砂,形成含硅粒子的粗糙覆盖表层,此系统可降低传统喷砂对瓷边缘薄弱部位的损伤,提高修复体边缘密合度;新型混合非功能性硅烷偶联剂与陶瓷表面可形成稳定且高强度的硅氧烷键,其水解稳定性远高于传统的硅烷偶联剂,利用硅氧烷在界面处与聚合物交联形成的互穿网络体系,可更有效地将树脂共价接枝到硅烷表面,有效提高氧化锆陶瓷与树脂的粘接强度,为修复体提供足够的固位力,提高临床修复成功率。

Abstract:

BACKGROUND: Zirconia ceramics with good physical and chemical properties and biocompatibility have been widely used in the field of dental reconstruction, but how to modify zirconia ceramic surface in order to improve the bonding strength of the restoration and tooth becomes a clinical difficulty.
OBJECTIVE: To review the oral zirconia ceramic bonding methods.
METHODS: A computer-based search of PubMed database was performed using the key words of “zirconia, silane coupling agent, resin cement, bonding”.
RESULTS AND CONCLUSION: Chemical friction silicon coating system is combined with the new non-functional silane coupling agent to perform surface modification of zirconia ceramics, and small-size (50 µm) alumina powder containing silicon particles is used for ziroconia blasting to form a silicon-contained coarse covering layer. This system can reduce the damage to porcelain edge induced by traditional blasting method, and improve restoration marginal adaptation. The new mixed non-functional silane coupling agent can form a stable and high-strength siloxane bond on the ceramic surface, and this agent shows a better hydrolytic stability than the traditional silane coupling agents. The interpenetrating network system between siloxane and the polymer at the interface can more effectively graft the resin covalently to the silane surface, effectively improve the bonding strength of zirconia ceramics and resin, provide sufficient retention for restoration, and improve the clinical success rate.
