Abstract:
The measurements of micro-hardness was achieved with a view to studying the influence of chemical composition and fabrication with a view to obtain metal-ceramic dental restorations. The materials used were specimens of metal alloys (Remanium Cs) and specimens of metal alloys-ceramics (Remanium-Biodent ceramic) prepared through polish, lustre and acid attack; the PMT3 machine for microhardness measurements; a 50 grams weight and a length of loading 15 sec. The results of determinations are prove the technological process for cover metal structure of Remanium Cs with ceramics influence significantly the microhardness of metal ingot and Remanium further polish (with and without oxidation).
