本研究的目的是评价金属调理剂对贵金属合金的粘接性能。由一种贵金属合金制成的铸盘试样用氧化铝喷砂，然后不进行处理或用两种不同类型的金属调节剂打底。在金属表面放置一个模具，并填入水泥。每组10个样品在37℃蒸馏水中保存24小时，然后以1.0 mm/min的十字头速度进行剪切试验。采用方差分析和Tukey’s HSD检验（α =0.05）。使用金属调理剂后，树脂改性玻璃离聚体水泥的平均粘结强度显著提高，表明金属调理剂在提高粘结强度方面的有效性。基于本研究的结果，在树脂水泥中加入功能单体以提高与贵金属合金的结合强度似乎是一种有用的方法。
The purpose of this study was to evaluate the adhesive performance of luting cements to a noble metal alloy treated with metal conditioners. Cast disk specimens made of a noble metal alloy were gritblasted with alumina followed by no treatment or priming with two different types of metal conditioner. A mold was placed on the metal surface and filled with luting cement. Ten samples per test group were stored in 37 degrees C distilled water for 24 hours, then shear tested at a cross-head speed of 1.0 mm/minute. ANOVA and Tukey's HSD tests (alpha=0.05) were done. The mean bond strength of resin-modified glass ionomer cement increased significantly with metal conditioner application compared to the controls, indicating the efficacy of the tested metal conditioners in improving bond strength. Based on the results of this study, it seemed to be a useful method to incorporate a functional monomer into resin cements so as to improve the bond strength to a noble metal alloy.
