本实验模拟人体口腔生理环境,研究了铸造陶瓷修复体——牙体界面状态不同处理方式和不同粘结剂对铸造陶瓷全冠生物强度的影响。发现粘结强度明显影响铸造陶瓷全冠粘结后的整体强度、界面处理方式既影响陶瓷冠与牙体组织的粘结强度,又影响冠粘结后的强度。 In this study, we simulate the physiological environment of human oral cavity and studied the effects of different treatment modes and the different binders on the biological strength of cast ceramic crowns. It is found that the bond strength significantly affects the overall strength of the cast ceramic crown after bonding. The interface treatment method not only affects the bond strength between the ceramic crown and the tooth body, but also affects the strength after the crown bond.
