RESUMEN
Several modifications of copper amalgams were examined. The findings evidence that of the amalgam constituents only copper passes into saliva, nutrient media, and animal body tissues and accumulates there. The findings of sanitary chemical and toxicologic studies helped select a hygienically optimal copper amalgam sample exerting no detrimental effects on the body.

The process of encapsulation of SKTN liquid silicone rubber of 30-50 thousand molecular weight, and of SKTN compounds curing in the tissues was observed experimentally. The silicone implants were surrounded by mature connective tissue after 3.0-4.5 years. The method of silicone administration, whether by injection or by implantation of prefabricated solid prostheses, exerted no effect on the local tissue reaction.
