The effect of cleansing agent on mechanical properties of acrylic denture base material

Acrylic CAD/CAM (Computer-Aided Design, /Computer-Aided Manufacturing) machining resins blocks or 3D printing process fabricates dentures more easily than conventional methods. The aim of this study was to investigate the effect of denture cleansers on dentures with different fabrications. PMMA specimens (conventional, CAD/CAM and 3D printed) were divided in groups with different cleaning procedures: water (control) hypochlorite, ac. acetic, H2O2, sodium bicarbonate. Mechanical tests were performed and statistically analysed. Cleansers can alter the surface of denture base resins and should be used depending on the PMMA fabrication
