ABSTRACT:To evaluate and compare the mechanical properties and wetting ability of heat polymerized polymethyl methacrylate resin after reinforcement with halloysite nanotubes and titania nanoparticles. A conventional heat-cured resin (DPI heat cure material) will be used as the matrix component while halloysite (group A) and titania (group B) nanoparticles as a reinforcing agent. Group C specimens will be fabricated with trevalon (Trevalon – HI). The specimens will be stored in distilled water overnight to simulate oral environment before performing the tests for determining the flexural strength (FS) and contact angle (CA). The contact angle data states that Halloysite reinforced PMMA is more hydrophilic. UTM analysis states that Flexure strength of trevalon highest amongst all the three group. Resin reinforced with halloysite had higher contact angle hysteresis hence greater retentive value and wetting ability while travelon had higher flexure strength.
