Effectiveness and durability of resin and amalgam restorations, comparative study Efectividad y durabilidad de restauraciones de resina y amalgama, estudio comparativo

Abstract

Introduction: Among the most used materials for direct restorations, we have composite resin and silver amalgam. The objective of this work is to identify the restoration that has the greatest effectiveness and durability between amalgam and resin in the mouth. Methodology: Several articles in Spanish and English published from 2000 to 2020 were selected; the search was carried out in PubMed, Medline, Science Direct, Elsevier, Cochrane. 100 articles were reviewed and 30 were selected including meta-analyzes, systemic reviews, clinical trials, randomized controlled trials, in vitro studies Results: The main cause that affects the durability and effectiveness of composite resin is secondary caries, while in amalgam it is the fracture. Conclusion: Composite resin and amalgam restorations have several advantages and disadvantages. Currently the material of choice for direct restorations is composite resin due to its excellent properties such as its high aesthetics; on the other hand, amalgam has greater durability, however, due to its disadvantages, it is no longer the main material of choice.
