Abstract

A new, simple method of modifying the adherend metal surface by a liquid Ga-Sn alloy (Adlloy) was applied to dental precious and base-metal alloys for adhesion with 4-META adhesive resin. Adhesions of 4-META resin to three other surface states--as-polished, oxidized at high temperature, and electroplated tin--were also performed for comparison with the adhesion on Adlloy-modified surfaces. Bond strength measurements were made, and the durability against water at the adhering interface was evaluated. The Adlloy-modified gold alloys (Type IV and 14 K) and silver-based alloys (Ag-Pd and Ag-Cu) showed not only high bond strengths but also excellent water durability at the adhesion interface. Surface modification by Adlloy, however, did not affect adhesion to Ag-In-Zn and base-metal (SUS, Co-Cr, and Ni-Cr) alloys. Adhesion to the tin-electroplated specimens was comparable with that to the Adlloy-modified specimens.

摘要

一种通过液态镓锡合金（Adlloy）对被粘金属表面进行改性的新型简单方法被应用于牙科贵金属合金和贱金属合金，以使其与4-META粘结树脂粘结。还对4-META树脂与其他三种表面状态——打磨态、高温氧化态和电镀锡态——的粘结情况进行了测试，以便与Adlloy改性表面的粘结情况进行比较。进行了粘结强度测量，并评估了粘结界面处的耐水性。Adlloy改性的金合金（IV型和14K）以及银基合金（Ag-Pd和Ag-Cu）不仅显示出高粘结强度，而且在粘结界面处具有出色的耐水性。然而，Adlloy表面改性对Ag-In-Zn合金和贱金属（SUS、Co-Cr和Ni-Cr）合金的粘结没有影响。电镀锡试样的粘结情况与Adlloy改性试样的粘结情况相当。
