To analyze the effect of different silane coupling agents on the resin bond durability of glass-infiltrated alumina ceramic. Methods A glass-infiltrated alumina ceramic was silanized or not by three silane coupling agents. The treated ceramic surfaces were bonded with two resin cements. Their micro-bond strength were measured after 0, 30,000 thermal cycles.
Before thermal cycling, resin cement A had lowest bond strength to ceramic, and ceramic treated by silane coupling agent A with two cements had lower bond strength than those treated by silane coupling agent B and C. After thermal cycling, cement A had no bond strength with no treated ceramic, only ceramic treated by silane coupling agent A with two cements had more than 5 MPa bond strength.
The glass-infiltrated alumina cermaic treated by the silane coupling agent activated by 10-methacryloyloxydecyl-dihydrogen phosphate could obtain better bond durability with different type of resin cements.
分析不同硅烷偶联剂对玻璃渗透氧化铝陶瓷树脂粘结耐久性的影响。方法：用三种硅烷偶联剂对玻璃渗透氧化铝陶瓷进行硅烷化处理或不处理。将处理后的陶瓷表面与两种树脂水门汀粘结。在0、30000次热循环后测量其微粘结强度。
热循环前，树脂水门汀A与陶瓷的粘结强度最低，用硅烷偶联剂A处理的陶瓷与两种水门汀的粘结强度低于用硅烷偶联剂B和C处理的陶瓷。热循环后，水门汀A与未处理的陶瓷无粘结强度，只有用硅烷偶联剂A处理的陶瓷与两种水门汀的粘结强度超过5MPa。
用磷酸二氢10-甲基丙烯酰氧基癸酯活化的硅烷偶联剂处理的玻璃渗透氧化铝陶瓷能与不同类型的树脂水门汀获得更好的粘结耐久性。
