Abstract

Introduction: The incorporation of antimicrobials into acrylic resins promotes the reduction of pathogenic microorganisms and positive impact on the health of users of prosthetic devices. This incorporation may cause changes in the physicochemical and mechanical properties, such as impact strength. Objective: The objective was to answer the question “Does the incorporation of antimicrobials alter the impact strength of acrylic resins?” Methods: The Preferred Reporting Items for Systematic Reviews and Extension of Meta-Analyses for Scoping Reviews (PRISMA-ScR) Checklist guidelines were used. SCOPUS, PubMed, EMBASE, and Science Direct databases were used with the custom search strategy. Studies were selected in two steps. Risk of bias analysis was performed with the quasi-experimental studies tool by the Joanna Briggs Institute (JBI). Results: As a result, 826 articles were found in the databases, and after removing duplicates and applying the proposed eligibility criteria, 11 studies were selected for the qualitative analysis. After applying the JBI tool, a low risk of bias was deferred to all studies. Due to the heterogeneity of the studies, it was not possible to provide a meta-analysis. Conclusion: The incorporation of antimicrobial agents into acrylic resins can, depending on the antimicrobial and the incorporation technique, affect impact strength.
