    Evaluation of Some Mechanical and Optical Properties of Zirconia and Lithium Disilicate Materials After Hydrothermal Aging
    Author(s): Zakariya Mohammed Al-Saffar* and Ahmed Asim Al-Ali

    Background: Dental ceramics have become a very popular material for the manufacturing of fixed dental prosthetics, a new manufactural technique was introduce recently , for construction of new zirconia blank that consist of two generation of zirconia in order to get the benefit of both generation to get more durable an esthetic restoration. Aims of the study: Evaluate the effects of hydrothermal aging on the flexural strength and translucency for tow type of zirconia and lithium disilicate, and to compare them with each other Materials and methods: Forty five samples have been prepared from tow type of zirconia (ZirCAD MtMulti (4Y-5Y); ZirCAD Prime (3Y-5Y)) and lithium disilicate (IPS e.max CAD HT). Ten samples was used to test flexural strength form each type dental ceramic (half of them before aging and half after aging); five samples used.. Read More»
