CR-COBALT ALLOYS AND TECHNOLOGICAL ASPECTS INVOLVED IN THE REALIZATION OF METAL INFRASTRUCTURE WITHIN SKELETAL PROSTHESES

Abstract

The aim of this study is to bring back to the present the Cobalt chromium alloys extremely used by their properties in dental medical practice respectively in the realization of the skeletons of partially mobilizable skeletonized prostheses through a careful analysis of the technological aspects that lead to successful results. Their biocompatibility has been certified after 60 years of use in the design of partial dentures, presenting excellent flow properties and a modulus of elasticity that gives it a high degree of rigidity. Corrosion resistance is closely related to the chemical composition, which is very stable. Metal alloys have diversified their structure over time in order to achieve that structure that offers an optimal biomechanical behavior adapted to different clinical characteristic
