Evaluation of the bond strength and characteristics of zirconia after different surface treatments

ConclusionsAirborne-particle abrasion resulted in a significant increase in surface roughness compared with the other groups. After nonthermal plasma treatment, the contact angle of the zirconia surface decreased within 48 hours. Nonthermal plasma application for surface treatment of zirconia showed no significant difference in bond strength when compared with airborne-particle abrasion. (Source: Dental Technology Blog)
