Elaboração de protocolo : acabamento e polimento de restaurações anteriores em resina composta.

Abstract

The direct restoration in composite resin are indicated as the first option in most cases of aesthetic rehabilitations. However, it depends on the finish steps and polish to guarantee better durability, tissue integrity and a perfect mimicry between the tooth and the restoration, making them polished and imperceptible to the patient. The goal for this study was to elect one simple and efficient protocol for finishing and polishing the composite resin Microhíbrida Charisma ®️ Classic (Heraeus Kulzer, Germany), using requested tools from the list of supplies for the class of Dentística Restauradora UNISC. For this to be achieve, 22 samples were made, having 2 of those sent to the control group, and the remaining distributed in 4 groups ( A, B, C and D) submitted to different sequences using diamond tips (KG Sorensen), discs systems (Praxis – TDV), abrasive rubber (Ultra-Gloss, American Burrs), silicon carbide brush (Ultra-Brush, American Burrs) and felt with polishing paste (Diamond R). By the end, the visual aspects os the samples were analyzed through the Zeiss Optical Microscope (Zeiss, Thuringia, Germany), with a 5x magnification. The four groups manifested considerable alterations on the analyzed surfaces. The pictures show that group A, which associated different materials, such as the diamond tip F, thick sanding disc, medium abrasive rubber and silicon carbide brush resulted in a most uniform and polished surface.
