ABSTRACT

The relevance of the study is dictated by the need to increase the efficiency of prosthetic treatment of patients with full absence of teeth, through the introduction of new composite materials, the use of which provides high strength of prosthetic structures, as well as the development of methods for the manufacture of full removable plate denture using modern digital technologies, which in general contributes to increase the service life of dentures, especially in the presence of difficult clinical conditions. Purpose of the work: increasing the efficiency of prosthetic dental treatment of patients with full absence of teeth on the basis of the development and implementation of a new design of a full removable plate denture with a base made of acrylic resin and an introduced frame made of composite material based on fiberglass. Materials and methods: taking into account the analysis of data from domestic and foreign literature, a design was developed and a technology for manufacturing a full removable plate denture with a combined basis was proposed, the frame of which was made of composite material Trinia. In the course of the work, the morphology and microstructure of a new combination of polymers were studied, and also, in a comparative aspect, their physical and mechanical properties were evaluated. Results: during the study of the microstructure, we found that the composite material based on glass fiber has a chemical bond with acrylic resin and a high homogeneity of the structure. Physicomechanical tests showed that when the base resin is reinforced with Trinia material, an increase in the strength of the samples under study is noted, which exceeds the existing analogues. Clinical and laboratory stages of manufacturing a new design, combining analog and digital methods, have been developed and tested. Conclusions: the introduction of a composite material into the design of a combined full removable plate denture will improve the strength properties of its base, increase performance and reduce weight. The use of digital technology will enable the use of high-strength composite materials.
