Fatigue Resistance of Y-TZP/Porcelain Crowns is Not Influenced by the Conditioning of the Intaglio Surface

Clinical Relevance In this study, very few Y-TZP frameworks failed, but the porcelain veneers frequently chipped. Cementing with an adhesive resin cement helped veneers survive larger fatigue loads without chipping. Treatment of the intaglio surface of the crowns neither helped nor hurt fatigue resistance.
