Description
Summary:Polymethyl methacrylate (PMMA), widely used in orthodontics and dentures, exhibits suboptimal mechanical properties, including flexural strength (FS), impact strength (IS), and tensile strength (TS), which are critical for ensuring durability, resistance to fracture, and overall functionality of dental appliances. Silver nanoparticles (AgNPs) are a promising filler due to their antimicrobial properties. This pre-registered PRISMA-compliant meta-analysis compared the mechanical properties of PMMA/AgNP composites to pure PMMA, considering mean particle size and concentration. Of 360 records from ACM, BASE, PubMed, and Scopus, 35 studies were included (κ = 0.91), covering 88, 38, and 11 tests on FS, IS, and TS, respectively. FS increased only between 30–70 nm (r = 0.00; ρ = 0.03; R [sup.2] [sub.deg2] = 0.13). IS remained higher for
