Characterization of Bulk-Fill Resin Composites in Terms of Physical, Chemical, Mechanical and Optical Properties and Clinical Behavior

Abstract

This study aims to evaluate the physical, chemical, mechanical and optical properties of Bulk-Fill resin, in relation to the literature and its proper clinical uses. A bibliographic search was performed in the main health databases PUBMED (www.pubmed.gov) and Scholar Google (www.scholar.google.com.br), in which articles published from 1994 to 2020 were collected. Laboratory studies, case reports, systematic reviews and literature reviews, which were developed in living individuals, were included. Therefore, articles that did not deal with the characteristics of the Bulk-Fill resin and its proper clinical uses were excluded. The use of Bulk-Fill resin has been progressively increasing over the years, presenting good properties, achieving success in clinical performance, ease of handling and thus has become the material of choice for dentists. In addition, its longevity demonstrates durability with mechanical properties and resistance to tooth structure. Bulk-Fill resins have characteristics similar to traditional composite resins, when performed according the usage protocol. With the use of this group of resins in a single increment, possible failures that occur during the restorative procedure can be minimized, such as: less chance of incorporating bubbles and a volumetric contraction with less stress on the interface.

Shear Bond Strength of NuSmile- Neoputty Bio- ceramic Material to Four Different Restorative Materials Used In Pedodontics.

“…An additional special feature possessed by this composite material is its low viscosity, which allows self-leveling and self-adaptation to the cavity walls. (13) The application of an adhesive for bonding of MTA based materials to dental resin composites gained a great confirmation in the dental literature. The 10-Methacryloyloxydecyl dihydrogen phosphate (MDP) containing universal adhesives were found to be able for creating a strong chemical bond with hydroxyapatite, by inducing surface dissolution of hydroxyapatite crystals; with subsequently formation of water resistant MDP-Calcium salts.…”

Low shrinkage bulk-filled dental resin composites with non-estrogenic dimethacrylate

“…As one kind of resin composite that can achieve a curing depth of more than 4 mm at one time, bulk-fill resin composites have been increasingly applied as dental restorative materials in clinic. 1,2 Compared to conventional dental resin composites (DRCs), the use of bulk-fill DRCs could shorten operation time and reduce the production of air bubbles between layers and the likelihood of postoperative symptoms such as saliva contamination and pulp irritation. 3 This requires bulk-fill DRCs to have low polymerization shrinkage, good operation performance and low cytotoxicity while ensuring qualified curing of the material.…”

Injectable Composite Resin Technique: An Alternative for Anterior Esthetic Restorations - Case Report

“…In 1955, Buonocore improved the adhesion of acrylic resins to enamel through the use of phosphoric acid. In 1962, Bowen developed the Bis-GMA monomer, which was later polymerized by an ultraviolet light source (Hervás-García et al, 2006;Matos et al, 2021). The increase in composite resin use was mainly due to the bond strength of this material with the dental substrate.…”

“…Mockups using acrylic resin and transparent index with injected fluid resin have become popular for making provisionals for anterior teeth (Gouveia et al, 2017). Flowable resins have low viscosity and offer high wettability of the tooth surface, ensuring penetration into all irregularities and the formation of layers of a minimum thickness (Hervás-García et al, 2006;Matos et al, 2021). Studies conducted to improve the mechanical properties of flowable resins resulted in the addition of nanoparticles to their composition.…”
