Evaluación del asentamiento en incrustaciones overlay, elaboradas en resina compuesta (3m ESPE Filtek P60), mediante técnica indirecta, utilizando matriz de silicona transparente en dientes premolares y molares inferiores.

Abstract

Abstract Introduction: With the intention of improving clinical performance and reducing the technical difficulties presented by clinical work in the oral cavity, indirect composite resin restorations arise, which can be made quickly and simply and allow control of aesthetic and functional factors. Inlays are one of the oral rehabilitation procedures with high aesthetic demand. This type of restoration, in all cases, has functional, biocompatibility and aesthetic repercussions and, together with other factors, settlement is an important criterion when evaluating quality. In oral rehabilitation and precision is a crucial point to satisfy biological, physical or aesthetic requirements. Objective: Evaluate the margin of error in overlay inlays, made in composite resin, by indirect technique in premolar teeth and lower molars, to determine if the transparent silicone matrix technique turns out to be a successful technique, success that will be determined in the settlement of the restoration . Methodology: The descriptive format was adopted with the use of a lower arch master model, in which the premolar and molar teeth were taken as study reference teeth, overlay-type preparations were made and they were duplicated in geller form, the inlays were made by applying an indirect technique with a transparent silicone matrix, the settlement of said inlays was evaluated by making a sagittal cut to each tooth, seven measurements were made in each of the teeth with a stereomicroscope and each of the values obtained were compared. Results: In the group of molars, point 1 and point 7 showed significant differences with respect to the values of the second left molar. In the premolar group there were no significant differences on the right and left side with respect to the marginal settlement. Conclusions: Overlay-type inlays made with resin are a type of successful treatment. According to the results, it can be seen that they present better marginal settlement compared to inlays made of ceramic. Keywords: Settlement, Inlay, Indirect restorations, Overlay.
