There are many technical factors affecting the properties of the final sintered zirconia restoratives: e.g. machining, firing, surface treatment, heat treatment and porcelain veneering, etc. Especially, the final firing of the zirconia has a great role on their properties. Sintering shrinkage, Vickers hardness, light transmission and flexure strength remarkably increased with the sintering temperature up to 1350°C and little changed above it. The apparent grain size continuously increased with the sintering temperature up to 1500 or 1550°C. Furthermore, the final sintering with some dental materials contaminated on the zirconia surface reduced their strength. On the other hands, the sandblasting increased the surface roughness and the susceptibility of low temperature degradation. The heat treatment after the sandblasting reduced the susceptibility of low temperature degradation.
