| Abstract | ||
| Acrylic teeth are chemically bond to the denture base material and are easier to adjust so that preferable on porcelain teeth but the most de bounding between teeth and denture base occur inside the patient mouth during function when the contact area between teeth and denture base was exposed to tensile strength. The Aim of this study: evaluate the tensile bond strength of acrylic teeth after reinforcement the denture base after addition (ZnO) nanofillers materials to PMMA with different concentrations(2%, 4%, and 6%).Materials and methods: Forty specimens of heat cure acrylic resin (PMMA) were prepared and divided into four groups 10 specimens for each groups as follows; Control Group (Group1) without ZnO nanofillers particles ; Group (2) with 2% by weight of ZnO ;Group (3) with 4% by weight of ZnO and Group (4) with 6% by weight of ZnO, wax pattern sample which used for acrylic cylindrical shape fabrication were (25 mm in length and 5mm in diameter ,the base of the cylinder which is 5mm in thickness and 8mm in length). Tensile bond strength of all specimens was evaluated. Results: showed the highest mean value was recorded by PMMA+ZnO 2% (6.4093) while the lowest mean value was recorded by PMMA+ ZnO 6%(3.9824). Conclusions: There were significant difference between control group PMMA and (PMMA+ZnO 4%, and PMMA+ZnO 6%) and there was no significant difference between control group PMMA and PMMA+Zno 2%. | ||
