Abstract

The purpose of this study was to examine the released titanium from casted isolated titanium and casted titanium coupled with other dental alloys (gold, Au-Ag-Pd, and Ag-Sn-Zn alloys) by the immersion test. After 3 weeks of immersion, titanium released into solutions were measured by ICP-AES.<BR>The results were as follows:<BR>1. Titanium released from isolated titanium test pieces in 1.28mM lactic acid were significantly more soluble than that in artificial saliva, saline solution, 1.28mM formic acid, and 1.28mM acetic acid.<BR>2. Titanium released from coupled titanium test pieces in lactic acid were more soluble than that in artificial saliva, saline solution. However, the released amount of titanium in lactic acid seemed to be attenuated by combining with gold, Au-Ag-Pd, and Ag-Sn-Zn alloys.
