РЕСТАВРАЦИЯ ЗУБОВ НА ОСНОВЕ КОНЦЕПЦИИ «ПРЕДВАРИТЕЛЬНОГО ПОЛИРОВАНИЯ ДЕНТИННОГО СЛОЯ КОМПОЗИТА»

Abstract

After studying various methods of restoring teeth in the oral cavity, we came to the conclusion that no one technique is perfect. This article describes clinical cases, as well as laboratory studies that allow us to judge the effectiveness of dental restoration based on the concept of "pre-polishing of the dentin layer of the composite". The quality of the surface characteristics of the restorations of the anterior group of teeth made of pre-polymerization composite materials was analyzed. The aesthetic restoration of teeth was performed using the classical method of layer-by-layer application and photopolymerization of the composite, as well as the proposed method based on the concept of pre-polishing of the dentin layer of the composite material. After adequate anesthesia and odontopreparation, a portion of the composite material that recreates the dentine layer is introduced into a pre-prepared and isolated from the oral fluid cavity, adapted to the hard tissues of the tooth, and then photopolymerized with a dental lamp. Next, the created layer is polished to a mirror shine and re-adhesive treatment with a self-etching adhesive system, photopolymerization. The next transparent layer of the composite material, imitating enamel, is applied to the "petal" of the polished dentine (inner) layer of the material to the enamel-dentine border with the obligatory imitation of mamelon and the surface structure of the restored tooth and its cutting edge is formed in a generally accepted way. After the final photopolymerization, the final grinding and polishing is carried out. The proposed method of aesthetic restoration of teeth, based on the concept of pre-polishing the dentine layer of the composite material, allows you to achieve a higher quality of restoration, and guarantees long-term preservation of color, gloss and edge fit of the restoration of the frontal group of teeth.
