The effect of nano titanium oxide particle incorporation on characteristic of denture base material

Abstract

State of problem: heat cure acrylic denture base material considers as the widely used type of material in complete denture construction but still need to improve its mechanical properties. The aim of the current work was to assess the result of incorporation of 3% wt of Titanium oxide Nano particles (silanized) on some characteristic of Polymethylmethacrylate denture base material. Materials & methods: 80 samples were constructed, 40 samples were constructed from heat cured PMMA had no incorporation (control) and 40 samples were constructed from heat cured acrylic by the incorporation of Titanium oxide Nanoparticle by probe ultrasonication apparatus. Each set of samples was distributed into four sub groups according to the examined test be accomplished. Results: the tensile strength and wettability were detected a highly significant increase by the adding of Titanium oxide Nano particles while no significant effect in porosity then color stability test. Conclusions: adding of 3% wt of TiO2Nano particles (silanized) to Polymethylmethacrylate denture base material increase the tensile strength and wettability of heat cured denture base material on the other hand this incorporation had no effect on porosity and color stability.
