Biofabrication of TiO2 Nanoparticles and Their Effect on the Mechanical and Rheological Properties and UV-Absorption of the Rapid Prototyping Epoxy-Based Composites for Dental Photosensitive Resins

In this investigation we have showed the synthesis of TiO2-NPs using Rosa hybrida leaf extract and studied using various spectroscopic and microscopic techniques. The as prepared photosensitive TiO2-NPs based nanocomposite have been used, to alter the epoxy-based light-sensitive resin, by carrying the goal of achieving express prototyping dental resources, where TiO2-NPs acted as reinforcing fillers. We enhanced the hardness of the nanocomposite material using TiO2-NPs filler, which plays as a significant parameter in the technique of dental impression. Further, the prepared composites are also studied about the light absorption, mechanical properties and viscosity. It is found the enhanced mechanical properties of the nanocomposites indicating the potential of TiO2-NPs for stereolithography and digital light processing that can be useful for preparation of the high dimensional accuracy dental model.
