Projeto, produção e validação de discos em compósitos poliméricos para produção de prótese dentária

Abstract

This work focuses on the study of the production of polymeric discs from resins derived from vegetable oils, intended for the manufacture of dental prostheses. The use of these resins is aligned with the principle of sustainability, in addition to presenting mechanical properties compatible with both requirements for the insertion of this material in the world market. The research investigates the addition of fiberglass to the polymer matrix with the objective of improving the mechanical properties of the discs, comparing it with polymeric discs produced without the insertion of fiber. The results obtained indicated that the polymeric disc showed good machinability, enabling the manufacture of complex shapes with high dimensional precision. The compression test showed that not all fiberglass-reinforced discs performed better than the resin and calcium carbonate discs, and some bending tests did not result in satisfactory maximum stresses. However, it was evaluated that, in future projects, small modifications in the polymer matrix may allow obtaining a sustainable and viable material for the production of fiberglass-reinforced prostheses.
