INVESTIGATIONS ON MECHANICAL PROPERTIES OF TITANIUM REINFORCED GLASS IONOMER CEMENT (GiC) - CERAMIC COMPOSITES SUITABLE FOR DENTAL IMPLANT APPLICATIONS

Reinforcement of high strength, corrosion resistant materials to conventional ceramic composites effects on improvement of wear resistance, hardness and other mechanical behavior of the ceramics. In this paper it has been discussed about the effect of Titanium (Ti) metal powder (280 Mesh) is Reinforced with Commercially available Glass Ionomer Cement (GiC) to form a ceramic composites in the standard ratios of 8% and 16%. These composites samples were prepared in laboratory at room temperature and capsule dies were used for the preparation of the samples. All the samples were taken for wear, Scanning electron Microscope, Surface hardness, Diametrial tensile test, and Raman Spectroscopy. It is observed that the wear resistances of the Ceramic composites were improved in increasing the addition of Ti percentage, and greater hardness values were achieved on 8% of Ti addition to GiC ceramic composites. In SEM Images of the samples we have observed many cracks on the inner region because of setting time, from these, it is observed that settling time of these ceramic composites have greater role in the achievement of mechanic properties because, the inner region of the ceramic composites required more time to settle (Dry) when compared to the outer surface.
