This study aimed to evaluate the effect of adhesive systems based on a thiouracil monomer on bonding to silver-palladium-copper-gold (Ag-Pd-Cu-Au) alloy (Castwell M.C.12). Disk specimens were cast from the alloy and then air-abraded with alumina. The disks were bonded using six bonding systems selected from four primers and three luting materials. Shear bond strengths were determined both before and after thermocycling. Bond strength varied from 2.7 MPa to 32.0 MPa. Three systems based on a thiouracil monomer (MTU-6) showed durable bonding to the alloy, with post-thermocycling bond strengths of 22.4 MPa for the Metaltite (MTU-6) primer and Super-Bond, a tri-n-butylborane (TBB) initiated resin, 9.0 MPa for the Multi-Bond II resin, and 8.1 MPa for the Metaltite and Bistite II system. It can be concluded that a combination of thiouracil-based primer and TBB initiated resin is effective for bonding Ag-Pd-Cu-Au alloy.
本研究旨在评估基于硫脲嘧啶单体的粘结系统对与银钯铜金（Ag-Pd-Cu-Au）合金（Castwell M.C.12）粘结的影响。用该合金铸造圆盘试样，然后用氧化铝进行空气喷砂处理。使用从四种底漆和三种粘结材料中选出的六种粘结系统对圆盘进行粘结。在热循环前后测定剪切粘结强度。粘结强度在2.7MPa至32.0MPa之间变化。三种基于硫脲嘧啶单体的系统（MTU-6）对该合金显示出持久的粘结性，对于Metaltite（MTU-6）底漆和Super-Bond（一种由三正丁基硼烷（TBB）引发的树脂），热循环后的粘结强度为22.4MPa，对于Multi-Bond II树脂为9.0MPa，对于Metaltite和Bistite II系统为8.1MPa。可以得出结论，基于硫脲嘧啶的底漆和TBB引发的树脂组合对粘结Ag-Pd-Cu-Au合金是有效的。
