Propriedades físico-mecânicas, vantagens e indicações acerca das resinas bulk-fill: uma revisão de literatura

Abstract

Bulk-Fill type composite resins appeared on the market in the early 2000s, with the aim of minimizing working time, allowing the use of larger increments between 4 and 5 mm in thickness, in addition to presenting properties similar or even superior to those conventional resins, as they allow increments of up to 2mm in thickness. Therefore, this work aims to analyze the techniques used in the insertion of Bulk-Fill resins, seeking to understand their best applicability taking into account their physical and mechanical aspects, in order to elucidate a clinical protocol based on the literature to assist in the use of composites Bulk-Fill. Data searches were performed in: Pubmed, Scielo and BVS. The inclusion criteria used in the research were: Review articles, clinical studies and published clinical cases, written in Portuguese, English or Spanish. Those between 2012 and 2021 were chosen. The exclusion criteria included articles that were not published in scientific journals or that were not linked to the main subject. It is concluded that Bulk-Fill composite resins can increase the clinical productivity of dental surgeons, however, they should be used following the technique recommended by the manufacturer, always respecting the inherent properties of each type of resin.
