Effect of nanoparticle addition on antimicrobial properties for acrylic removable orthodontic appliance

Removable orthodontic appliances have acrylic resin-based plate components that often result in plaque retention and bacterial build-up, leading to dental and periodontal problems. Several studies have tried adding nanoparticles to acrylic resins to over-come these problems. This review discusses the effect of nanoparticle addition on the antimicrobial properties of orthodontic removable acrylic resin. A literature review was conducted on 10 articles obtained from PubMed, ScienceDirect, and Google Scholar by determining inclusion, exclusion and keyword criteria. Literature search using boolean search based on inclusion criteria obtained data that the addition of various nanoparticle materials such as zinc oxide, titanium dioxide, magnesium oxide produces good antimicrobial properties, especially in the process of inhibiting microbial adhesion. It is concluded that the addi-tion of nanoparticles to acrylic resin orthodontic appliances provides effective antimicrobial properties so that it can be applied clinically to prevent diseases in the oral cavity such as gingivitis and dental caries.
