Abstract：
The purpose of this study was to evaluate the effect of the atmospheric pressure plasma treatment as a surface treatment method on the contact angle and shear bond strength (SBS) of zirconia ceramics and the failure mode between the self-adhesive resin luting agent and zirconia. The zirconia specimens were divided into eight groups based on the surface treatment method: alumina blasting, air plasma, argon plasma (AP), Katana cleaner, ozonated water, ozonated water+AP, Katana cleaner+AP, and tap water+AP. The contact angles, SBS, and fracture modes were tested. AP treatment significantly reduced the contact angle (p<0.0001). The combination of AP and other cleaning methods showed a higher bond strength and more mixed fractures. Our findings indicate that using atmospheric pressure plasma with argon gas, combined with other cleaning methods, results in a stronger bond than when using alumina blasting alone.
摘要：
这项研究的目的是评估作为表面处理方法的大气压等离子体处理对氧化锆陶瓷的接触角和剪切粘结强度（SBS）以及自粘树脂粘结剂和氧化锆之间的破坏模式的影响。根据表面处理方法，氧化锆试样分为八组：氧化铝喷砂，空气等离子体,氩等离子体(AP),Katana清洁工，臭氧水,臭氧水+AP,Katana清洁剂+AP,和自来水+AP。接触角，SBS,并对断裂模式进行了测试。AP处理显著降低了接触角(p<0.0001)。AP和其他清洁方法的组合显示出更高的粘结强度和更多的混合断裂。我们的发现表明，使用大气压等离子体和氩气，结合其他清洁方法，结果在一个更强的结合比使用氧化铝爆破单独。
