Sažetak
Lithium disilicate and zirconia are the two most popular materials for aesthetic and dental pros- thetic work ; however, due to their limitations, a new material is being researched, namely zirco- nia-reinforced lithium disilicate, the surface of which is treated with different procedures to achieve the best possible surface properties. In this study, the surface of zirconia-reinforced lithi-um disilicate glass-ceramic was treated using different methods (conventional and laser) to deter-mine the effects of the treatment procedures on the surface properties and surface roughness to achieve a higher strength of adhesion from the self-adhesive resin cement to zirconia- reinforced lithium disilicate. The treated surfaces were investigated using profilometry, X- ray diffraction and energy dispersive X-ray fluorescence. The results obtained were statistically evaluated. The results show that the surface roughness is highest for the samples treated with Er:YAG (erbium-doped yttrium aluminium garnet laser) and silanisation. Furthermore, the surface treatment procedures applied did not change the composition of the surface.
