Estudo da influência da contração de polimerização em restaurações de resina composta: revisão de literatura

Abstract

INTRODUCTION: Composite resins offer aesthetic and functional alternatives for dental restorations. However, polymerization shrinkage is a challenge that may affect the longevity of restorations. OBJECTIVES: To understand the long-term impact of polymerization shrinkage. JUSTIFICATION: Considering the widespread use of these restorative materials in dental practice, this study aims to deepen understanding of polymerization shrinkage, an inherent phenomenon of this material, which is directly related to clinical outcomes. MATERIALS AND METHODS: A search for scientific articles was conducted in the following databases: Google Scholar, Virtual Health Library (BVS), National Library of Medicine (PubMed), Elsevier, and Scientific Electronic Library Online (SciELO), covering the period from 2014 to 2024. Inclusion and exclusion criteria were applied for article selection, as well as specific keywords on the topic studied. FINAL CONSIDERATIONS: This study reinforces the relevance of composite resins as an aesthetic and functional solution in dental restorations, while also highlighting the technical challenges imposed by polymerization shrinkage. The findings indicate that, although this shrinkage is an inherent phenomenon of the material, its impact on the longevity of restorations can be mitigated through improved clinical techniques and the selection of materials with properties that minimize adverse effects. Given the increasing use of composite resins in dental practice, knowledge about the implications of polymerization shrinkage is essential for professionals, enabling an evidence-based approach that contributes to the durability of restorations and patient satisfaction.
