Abstract
:
This study was performed to evaluate some mechanical properties of new composition of partially stabilized zirconia as an implant material sintered by two different degrees of temperature (1350°C and 1200°C). This properties include: 1- Flexure strength. 2- Compressive strength. 3- Shear strength. 4- Modulus of elasticity. 5- Thermal conductivity. Material: The material used in this study is a partially stabilize zirconia that composed of 3 powders (zirconium oxide 80%, yttrium oxide 3% and titanium oxide 17%). Tests and Testing Devices: For each test in this study, specimens were divided according to sintering temperature into : • Group A: Sintered at 1200 °C. • Group B: Sintered at 1350 °C. The Findings: There was a statistical significant difference between the mean values of the mechanical properties of specimens sintered at 1350°C and that sintered at 1200°C. The data of flexure, compressive and shear strength, modulus of elasticity and thermal conductivity of partially stabilized zirconia sintered at 1350°C was greater than that processed at 1200°C. Conclusions: From this study it can be concluded that: • Addition of yttrium oxide and titanium oxide in such ratio participated in lowering sintering temperature of partially stabilized zirconia. • 1350 °C sintering temperature seems to be a suitable degree for gaining favourable mechanical properties than 1200 °C. • The change in sintering temperature with selected titanium oxide, yttrium oxide and zirconium oxide ratio played an important role in improving partially stabilized zirconia properties. • Partially stabilized zirconia is a suitable material for the artificial dental root from the viewpoint of material technology and has a sufficient strength in occlusion.
