| Research Abstract |
This project researched on the benefit of laser assist etching as a surface treatment of zirconia, alumina, or lithium disilicate used for all-ceramic restorations. The shear bond strength with the CO2 laser yielded the higher value compared the air abrasion of alumina with the power setting of the laser. And the hydrofluoric acid etching made the micro-grooved surface, while the air abrasion conventionally brought the micro retentive surface on the contrary. The hydrofluoric acid etching moreover led the effectiveness of the improvement for the bond strength to resin cements.
