The aim of this research is to study the mechanical properties of porcelain
restorative material by using CO2 laser beam. (10) specimens of porcelain material
have been prepared. They divided into two groups with dimensions (4*10mm)
& (6*10mm) respectively.
Eight of these specimens are irradiated by CO2 laser device at different laser
powers (2,3,4,& 5) Watt at a fixed time (20 sec). The mechanical properties which
was tested, such as micro-hardness, diametrical strength, density, and porosity. The
value of micro-hardness, diametrical strength, density are increased at different
laser power except (3W), because internal deformation occurred in this laser power
density up to (3W). Glazed layer may be occur because the effect of (4,5) Watt
laser, consequently the value of porosity decreased.
