DISTURBANCES OF TECHNOLOGICAL PROPERTIES OF THE BASIC PLASTIC, ARISING OUT OF NON-COMPLIANCE OF THE POLYMERIZATION MODE

Abstract

Abstract. The main structural element of all removable laminar prostheses is the “base” of the prosthesis, it consists of base plastic, for the manufacture of which there are certain rules for the mode of polymerization. Often, we see a violation of the polymerization of basic plastics, which, in the opinion of the “violators”, should not lead to serious consequences, but there is no evidence that these violations do not entail consequences. Therefore, the purpose of our work was to study the consequences arising from a violation of the polymerization of the base plastic during cooking. Two types of plastics (control and experimental samples) were made, studies were carried out on the mechanical loading of these samples, and X-ray diffractometry was carried out for the presence of irregularities in the structure of the plastic. When conducting experimental studies revealed significant deviations in samples made with violation of the mode of polymerization, which may indicate a decrease in the life of removable laminar dentures on a plastic base. Also, data on X-ray diffractometer were obtained with different intensity and number of peaks of plastics manufactured with violation of the polymerization mode and without violation, data of plastics manufactured without violation of the polymerization mode in the future can become a standard that all dentures made on a plastic basis must meet.
