title: [Application of chrome-cobalt alloys containing titanium in inner and outer cone-telescope crown].
abstract: The chrome cobalt alloys containing titanium (Dentitan) has excellent porcelain-to-metal bond strength. Therefore, it is used as outer telescope crown alloys of cone telescope denture in actual clinic. The purpose of this study is to investigate the fitness and the change of metal before or after porcelain firing of chrome-cobalt alloys containing titanium. The results of this investigation indicate that (1) chrome-cobalt alloys containing titanium can be used as metal for inner crown because it showed the same degree of fitness compared with precious metal, and (2) the optimal water/powder ratio of the outer telescope crown was 28 ml; 2 ml, or 27 ml; 3 ml, and (3) although the full porcelain veneer-coverage was greater vertical distortion than the partial-veneer-coverage, either metal can be applied to outer crown by adjusting of the retention.
