The thesis is devoted to the complex (physico-mechanical, laboratory and clinical) investigations of cements for fixation of the constructions of partial prosthesises. There was conducted the comparative characteristics of properties of cements of different groups which are proposed for employment by the firms - producers. There was proposed the improved dental probe for determining of the quality of partial dental prosthesis fixation. The way of determining of long-lasting use of cement models in cyclic compression. The results of investigation of the cements which are proposed for fixation will give an opportunity to low the negative influence on the oral cavity tissues and to increase the terms of partial prosthesises use by the patients.
