四种不同处理方法对Ni—Cr烤瓷合金粘结强度的影响

The effects of four different retantive methods on the bond strength of Ni-Cr ceramic alloy

作者对制作烤瓷粘结桥的ＩＳＲＩ－Ｎｉ－Ｃｒ合金进行了喷砂、化学蚀刻、池式电解蚀刻和点式电解蚀刻等处理，以偶联剂ＫＨ—５７０涂在处理金属表面，用釉质粘结剂与离体牙粘结。采用扫描电镜观察处理金属表面形貌；并用ＭＴＳ陶瓷测试系统测其粘结强度。结果表明：点式与池式电解蚀刻在粘强度上无明显差异，并具有简单、清洁、方便临床医师椅旁操作等优点；粘结强度的顺序为电解＞化学和喷砂。

Abstract Iski Ni -Cr alloy which was made for resin bonded bridge was sandblasted, chemical etched,traditional electrolytic etched and spot electrolytic etched. The metal surface wes observed by SEM,then was abrasived by KH - 570 and bonded toetched teeth with an enamel bonding agent, andtested for shear bond strength. The results revealedthat there was no significant.difference betweentraditional and spot eletrolytic etching; spot eletrolytic etching had much more advantages.
