This paper presents the application of the in-situ synthesized nanocomposites of poly (methyl methacrylate) (PMMA) and TiO2 for use as dental materials. TiO2 nanoparticles with different percentages (1wt% and 2 wt%) were blended with PMMA through a melt compounding process. The prepared nanocomposites were characterized by a micro-indentation test, scratch test, and field emission scanning electron microscopy analysis. The effects of different vol. % of TiO2 on the mechanical properties of the composites were studied. The evaluation of the mechanical properties of the composites revealed that the utilization of TiO2 as a reinforcing agent strengthened the polymer. The morphological observation demonstrated the presence of significant adhesion between TiO2 and the polymer matrixes with a homogeneous distribution of TiO2 in the polymer matrix. The proper compatibilization between TiO2 and the polymer matrix enhanced the mechanical properties. Overall, this work may pave the way for the production of a new compatibilized TiO2-based blend for dental applications.
