“…According to the different methods of polymerization, there are heatcuring, self-curing and light-curing resins available, and the appropriate type is selected based on the purpose. Self-curing acrylic resins, which are polymerized by mixing polymer powder and monomer liquid at room temperature 3) . They are widely used in provisional prosthesis, temporary prosthetic base materials, repairing dentures and orthodontic removable appliances due to its desirable and handling characteristics: low cost, easy handling and processing, easy to polish and repair, and excellent esthetics and biocompatibility in the oral environment 4,5) .…”

Silanized aluminum borate whiskers (ABWs) of 4 wt%, silanized zirconium dioxide nanoparticles (nano-ZrO2) of 2 wt% were mixed with polymethyl methacrylate (PMMA) powder to get ZrO2-ABWs/PMMA composites. Titanium dioxide (TiO2), silver-supported titanium dioxide (Ag/TiO2), silver-supported zirconium phosphate (Novaron) and tetrapod-like zinc oxide whiskers (T-ZnOw) antibacterial agents of 3 wt% were mixed with ZrO2-ABWs/PMMA composites respectively to fabricate standard specimens. Plaque biofilms on the specimens surface were investigated for colony-forming units (CFUs). In addition, cytotoxicity and mechanical behavior were evaluated. Results showed that the CFUs values of S. mutans and C. albican biofilms on the four antibacterial composites surface were all reduced (p<0.05) compared to the blank and control groups. The antibacterial composites did not have an adverse effect on fibroblast growth in this study (p>0.05) except TiO2 and Ag/TiO2 groups of undiluted extracts. The flexural strength and surface hardness of Novaron and T-ZnOw groups were increased (p<0.05) compared to the control group.
