Damage tolerance of six dental zirconias with different translucencies
Karlsen, Cathrine Å; Schriwer, Christian; Øilo, Marit (Journal article; Peer reviewed, 2020)Purpose: High-translucent dental zirconia has been introduced as a suitable material for anterior monolithic restorations. The material composition differs from traditional 3Y-TZP both with regard to yttria content and ... -
Effect of cementation techniques on fracture load of monolithic zirconia crowns
Indergård, Janne Angen; Skjold, Anneli; Schriwer, Christian; Øilo, Marit (Journal article; Peer reviewed, 2021)The aim of this study was to evaluate the effect of cement on the fracture load of monolithic zirconia crowns with different yttria content (3 and 5mol%). A total of 62 monolithic zirconia crowns, 40 3Y-zirconia crowns ... -
Effect of margin design on fracture load of zirconia crowns
Skjold, Anneli; Schriwer, Christian; Øilo, Marit (Peer reviewed; Journal article, 2019)Zirconia‐based restorations are showing an increase as the clinicians’ preferred choice at posterior sites because of the strength and esthetic properties of such restorations. However, all‐ceramic restorations fracture ... -
The effect of preparation taper on the resistance to fracture of monolithic zirconia crowns
Schriwer, Christian; Gjerdet, Nils Roar; Arola, Dwayne; Øilo, Marit (Journal article; Peer reviewed, 2021)Objective Monolithic zirconia crowns have become a viable alternative to conventional layered restorations. The aim of this study was to evaluate whether the taper, and thus wall thickness, of the abutment or pre-defined ... -
Fractographic analysis of 35 clinically fractured bi-layered and monolithic zirconia crowns
Skjold, Anneli; Schriwer, Christian; Gjerdet, Nils Roar; Øilo, Marit (Journal article; Peer reviewed, 2022)Objectives The aim of this retrieval study was to analyze the fracture features and identify the fracture origin of zirconia-based single crowns that failed during clinical use. Methods Thirty-five fractured single crowns ... -
Monolithic zirconia crowns in the aesthetic zone in heavy grinders with severe tooth wear – An observational case-series
Hansen, Torbjørn Leif; Schriwer, Christian; Øilo, Marit; Gjengedal, Harald (Peer reviewed; Journal article, 2018)Objectives The aim of this study was to assess the clinical outcomes and patient satisfaction with monolithic zirconia crowns in patients with severe tooth wear (≥1/3 of the tooth crown) in the aesthetic zone. Methods The ... -
Monolithic zirconia crowns – wall thickness, surface treatment and load at fracture
Øilo, Marit; Schriwer, Christian; Flinn, Brian; Gjerdet, Nils Roar (Peer reviewed; Journal article, 2019)Purpose: The aim of this study was to evaluate the effect of wall thickness on load at fracture of monolithic zirconia dental crowns after aging. Materials and Methods: Seventy translucent monolithic zirconia crowns (DD ...
