Effect of zirconia surface treatment on zirconia/veneer interfacial toughness evaluated by fracture mechanics method

Conclusions The toughness of zirconia/veneer interface with no treatment is significantly higher than that of interfaces subjected to liner application and airborne-particle abrasion. Clinical relevance. Liner application and airborne-particle abrasion seem to reduce zirconia/veneer interfacial toughness. Therefore, the two surface treatment methods should be applied with caution.
