背景/目的：树脂粘结全瓷修复体的成功在很大程度上取决于获得可靠的粘结，这种粘结必须将系统的所有部分整合到一个连贯的结构中。在全瓷系统的应用中，仍然存在粘结问题，降低了修复体和水泥之间的临床成功率。本研究的目的是通过改变陶瓷材料的表面性质来确定表面处理方法是否能够增强水泥与全瓷材料之间的结合。材料和方法：采用四种不同的表面处理工艺(氧化铝喷砂、氧化铝喷砂和氢氟酸凝胶化学酸蚀、苏打和玻璃微珠喷砂、贝特曼酸蚀固位系统)作为表面处理程序。前三个程序被应用于IPS Empress和IPS Empress 2陶瓷光盘的样品。对In-Ceram陶瓷圆盘样品进行了Al_2O_3喷砂、苏打喷砂和玻璃微珠喷砂，以及贝特曼蚀刻固位系统。这些圆盘被粘合成复合棒。结果：对于IPS Empress和IPS Empress 2陶瓷盘，采用Rely X粘接树脂粘接后再用氢氟酸酸蚀刻组粘结效果最好。应用于In-Ceram材料的表面处理程序没有改变其结合强度。结论：本研究的体外研究结果表明，在考虑粘固剂类型的情况下，对IPS Empress和IPS Empress 2全瓷系统应用表面处理程序是重要的。相反，粘结剂种类和表面处理方法对In-Ceram陶瓷系统的结合强度没有影响。版权所有(C)2011，中国共和国牙科学会。爱思唯尔台湾有限责任公司出版。版权所有。
Background/purpose: Success with resin-bonded all-ceramic restorations is highly dependent on obtaining a reliable bond, which has to integrate all parts of the system into one coherent structure. There are still bonding problems that reduce the clinical success between restorations and cement in applications of full-ceramic systems. The purpose of this study was to determine whether surface-treatment methods can provide a stronger bonding between the cement and the full-ceramic materials by changing the superficial properties of the ceramic materials.Materials and methods: Four different surface processes (sandblasting with Al2O3, Al2O3 sandblasting and chemical etching with hydrofluoric acid gel, blasting with soda and glass beads, and the Bateman etch retention system) were used as surface-treatment procedures. The first three procedures were applied to samples of IPS Empress and IPS Empress 2 ceramic discs. Sandblasting with Al2O3, blasting with soda and glass beads, and the Bateman etch retention system were applied to samples of In-Ceram ceramic discs. The discs were cemented to composite bars. Two types of cement were used, Rely X adhesive resin cement and Rely X modified glass ionomer cement and, all the samples were subjected to a shear test to evaluate their bond strengths.Results: With the IPS Empress and the IPS Empress 2 ceramic discs, the best bonding was obtained in the group etched with Al2O3 sandblasting and hydrofluoric acid after cementation using the Rely X adhesive resin cement. The surfacing procedures applied to the In-Ceram materials did not change their bonding strengths.Conclusions: The in vitro findings from this study indicate that surface-treatment procedures applied to the IPS Empress and the IPS Empress 2 full-ceramic systems are important when cement types are considered. In contrast, cement types and surface-treatment methods had no effect on changing the bond strength of the In-Ceram ceramic system.
