This study aimed to evaluate the bonding behaviors of a gold alloy and a titanium-aluminum-niobium (Ti-6Al-7Nb) alloy after priming with three metal conditioners. Cast alloy disks were ground and divided into the following four conditions: (1) unprimed control versus priming with (2) Alloy Primer, (3) Estenia Opaque Primer, or (4) V-Primer. The disks were bonded with tri-n-butylborane (TBB) initiated methacrylic resin, and shear bond strengths were determined both before and after 20,000 times of thermocycling. Alloy Primer and V-Primer--which contained a vinyl-thione monomer--were effective for bonding the Au-Pt-Pd alloy. As for the hydrophobic phosphate monomer contained in Alloy Primer and Estenia Opaque Primer, it was effective for bonding the Ti-6Al-7Nb alloy. Further, when specimens were primed with Alloy Primer that contained both functional monomers, bond strength to Ti-6Al-7Nb alloy was greater than that to Au-Pt-Pd alloy.
本研究旨在评估用三种金属调节剂预处理后金合金和钛铝铌（Ti-6Al-7Nb）合金的粘结行为。铸造合金圆盘经过研磨并分为以下四种情况：（1）未预处理的对照，与用（2）合金底漆、（3）Estenia不透明底漆或（4）V底漆进行预处理。圆盘用三正丁基硼烷（TBB）引发的甲基丙烯酸树脂粘结，并在20000次热循环前后测定剪切粘结强度。含有乙烯基硫酮单体的合金底漆和V底漆对Au-Pt-Pd合金的粘结有效。至于合金底漆和Estenia不透明底漆中含有的疏水性磷酸单体，它对Ti-6Al-7Nb合金的粘结有效。此外，当用含有两种功能单体的合金底漆对试样进行预处理时，与Ti-6Al-7Nb合金的粘结强度大于与Au-Pt-Pd合金的粘结强度。
