New dental precious metal alloys for resin bonding without alloy surface modification were developed by adding base metals (In, Zn, or Sn). Before this, binary alloys of Au, Ag, Cu, or Pd containing In, Zn, or Sn were studied for water durability and bonding strength with 4-META resin. The adhesion ability of the binary alloys was improved by adding In equivalent to 15% of Au content, Zn equivalent to 20% of Ag content, and In, Zn, or Sn equivalent to 5% of Cu content. There was no addition effect of the base metals on Pd, however 15% of In addition improved adhesion with Pd-based alloys containing equi-atomic % of Cu and Pd. The alloy surfaces were analyzed by XPS and showed that oxides such as In2O3, ZnO, or SnO play an important role in improving the adhesive ability of the alloys.
通过添加贱金属（铟、锌或锡）开发出了无需合金表面改性的用于树脂粘结的新型牙科贵金属合金。在此之前，对含有铟、锌或锡的金、银、铜或钯二元合金进行了水耐久性及与4-META树脂粘结强度的研究。通过添加相当于金含量15%的铟、相当于银含量20%的锌以及相当于铜含量5%的铟、锌或锡，二元合金的粘附能力得到了提高。然而，贱金属对钯没有添加效果，不过添加15%的铟改善了与含等原子百分比铜和钯的钯基合金的粘附性。通过XPS对合金表面进行分析，结果表明诸如In2O3、ZnO或SnO等氧化物在提高合金的粘附能力方面起着重要作用。
