Abstract

Titanium offers biocompatibility and adequate mechanical properties for fabricating dental prostheses; however, casting difficulties can compromise the accuracy of titanium crown margins. The aim of this study is to evaluate the influence of different concentrations of the special liquid to titanium investment on accuracy of crown castings made with commercially pure titanium.
