Abstract

Science and technology of dental materials development provides variety of dental products that fulfils the needs of aesthetics and physical properties. There are wide ranges of aesthetics dental materials, one of them is dental composite. The use of inorganic ceramic nanoparticle filler on dental composite system has provides many advantages. However it have severals limitations due the use of polymer resins as matrix such as a low mechanical property. To overcome the problem, geoplymer nanocomposite materials of Al-Mg-Si-Zr used to substutute resin polymer. Geoplymer materials have reliable properties such as low density, easily processed, and low cost. The objective of this study is to synthesis four different types of inorganic ceramic fillers, alumina, magnesia, silica, and zirconia using sol-gel tecnique, with two differents alkali activator concentrations (8 M and 12 M) and then coorporate them with geopolymer as matrix to characterized its microstructure through XRD and SEM to know the phase characterization, crystal structure, and size. The X-Ray Diffraction and Scanning Electron Microscopes Characterized that, Al-Mg-Si-Zr have been formed with nano sized particles. Microscopic morphology of Mg-Al-Si-Zr nanocomposite with alkali activator concentration 8 M has more porosity than 12 M that lead to better mechanical property.
