Resin Composites in Posterior Teeth: Clinical Performance and Direct Restorative Techniques

Abstract

Resin composites are the most versatile restorative materials used in dentistry and the first choice for restoring posterior teeth. This article reviews aspects that influence the clinical performance of composite restorations and addresses clinically relevant issues regarding different direct techniques for restoring posterior teeth that could be performed in varied clinical situations. The article discusses the results of long-term clinical trials with resin composites and the materials available in the market for posterior restorations. The importance of photoactivation is presented, including aspects concerning the improvement of the efficiency of light-curing procedures. With regard to the restorative techniques, the article addresses key elements and occlusion levels for restoring Class I and Class II cavities, in addition to restorative strategies using different shades/opacities of resin composites in incremental techniques, restorations using bulk-fill composites, and shade-matching composites.

Mouthwashes: Surface Hardness and Accuracy of Dual-cured Visible Light-Cured Composite

“…Tables (1) and ( 2), and Fig. (3) and (4) show the results of surface hardness and accuracy of VLC composite filling study groups initially, after treatment with both distilled water (control group) and after immersion in GUM ® and Listerine mouthwash liquids for 1 week, 4 weeks and after dual-curing (light-curing). Following the comparison of the outcomes, there was a non-significant difference in the surface hardness in the control group, and between the treated groups, before treated, and after being treated with both GUM ® and Listerine mouthwash (p >0.05).…”

“…emitting diodes to set (1) , or a device with either blue light from a filtered halogen lamp; plasma arc units; or argon-ion lasers (2,3) . The superior composite aesthetic and mechanical properties nominate it to restore anterior and posterior teeth in clinical practice (4) . Its strongest micromechanical bonding retention to tooth structure is shown to be simple to develop adhesion in the oral cavity (5) .…”

Color and surface roughness alterations of bulk-fill resin composites submitted to simulated toothbrushing with whitening dentifrices

“…Conventional composites restore tooth cavities in increments of 2 mm, reducing tension during polymerization contraction and improving light absorption 1,2 . However, the conventional technique is time-consuming and increases operative error, leading to gaps, decreased bond strength, and early restoration fracture 3 .…”

Study on the mechanical and aging properties of an antibacterial composite resin loaded with fluoride-doped nano-zirconia fillers

“…With the enhancement of aesthetic requirements and the development of novel dental materials, tooth-colored materials like composite resins (CRs) have been widely used in dentistry. Due to their strong mechanical properties and good aesthetic characteristics, CRs have gradually become the most commonly used filling and adhesive materials in clinic, surpassing the use of traditional silver amalgam and the glass ionomer cement (GIC) ( Pizzolotto and Moraes, 2022 ; Aldowsari et al, 2023 ; Maletin et al, 2023 ). However, the occurrence of secondary caries at the edge of the CR restorations has become the main cause of secondary filling treatments ( Chladek et al, 2023 ).…”
