OBJECTIVE: The aim of this review is to investigate recent developments in dental resin composites. Furthermore, the processing steps such as cavity design, adhesion and polymerization are examined and how they affect the quality of a restoration. METHOD: Narrative literature review. The literature search is limited to the period 2017-2023. Articles examining composites for CAD/CAM applications were excluded, as were studies investigating composite for purposes other than direct restorations. CONCLUSIONS: Developments in the field of resin composites focus on the incorporation of nanoparticles into the matrix as well as antibiotic agents to tackle secondary caries. A minimally invasive cavity design is supported. The beveling of margins and the surface preparation by the operator are considered more important factors compared to the choice of material. With both etching modes, clinically acceptable results are achieved, and failures are more related to the resin composite material used. Incremental layering with up to 2mm increments is the standard technique. The polymerization shrinkage is material dependent. Increased irradiation distance negatively affects polymerization. KEY WORDS: Resin composite, Cavity design, Adhesive systems, Polymerization shrinkage, Polishing. |
