Abstract

The staff of the chair of hospital orthopedic dentistry and laboratory of material Science research medical-stomatological Institute of A. I. Evdokimov Moscow state medical and dental University after together with the specialists of JSC «of E.I. Rytvin NPK «Supermetall» developed a new Russian-based alloy of gold - Plagodent-Plus for metal-ceramic dentures. Conducted laboratory-experimental trials, which included physical-mechanical testing, experiment to assess the impact of investment material mass on the surface of castings, comparative tests, corrosion in the solution of artificial saliva, sanitary-chemical and Toxicological studies have shown that the new alloy Plagodent -Plus meets all the requirements, fixed in the modern Russian and international standards, and can be recommended for further studies in the clinic.
