氧化钇部分稳定氧化锆（YPSZ）陶瓷由于其高的断裂韧性和化学耐久性而适用于牙科和医疗用途。本研究的目的是检查牙科YPSZ陶瓷，Denzir的粘结行为。在进行各种表面处理后，Denzir样本使用粘合剂树脂复合材料、玻璃离子或磷酸锌粘固剂彼此粘合。然后通过剪切试验确定结合强度。SiC喷砂和Al2O3喷砂的试样之间没有观察到显著差异（p>0.05）。在所有表面处理中，剪切粘结强度显著（p玻璃离子水门汀>磷酸锌水门汀.此外，硅烷化与甲基丙烯酰氧基丙基三甲氧基硅烷略有增加的粘接树脂复合水泥的粘接强度。
Yttria partially stabilized zirconia (YPSZ) ceramics are suitable for dental and medical use because of their high fracture toughness and chemical durability. The purpose of this study was to examine the bonding behavior of a dental YPSZ ceramic, Denzir. After being subjected to various surface treatments, Denzir specimens were bonded to each other using an adhesive resin composite, glass ionomer, or zinc phosphate cement. Bonding strength was then determined by the shearing test. No significant differences (p>0.05) were observed between SiC- and Al2O3-blasted specimens. In all surface treatments, the shear bond strength significantly (p glass ionomer cement > zinc phosphate cement. Moreover, silanization with methacryloxy propyl trimethoxysilane slightly increased the bonding strength of the adhesive resin composite cement.
