Fracture Loads of All‐Ceramic Crowns under Wet and Dry Fatigue Conditions

Abstract

Fracture load of the three ceramic systems was found to be influenced by ceramic composition. Moreover, cement and fatigue condition influenced the fracture loads of the crown specimens evaluated in this study.

In vitro analysis of the fracture resistance of CAD–CAM monolithic zirconia molar crowns with different occlusal thickness

“…It was reported that adhesive bonding significantly increased fracture strength and improved marginal seal of all-ceramic crowns (Blatz et al 2008;Borges et al 2009;Lu et al 2013;Kern 2015). Furthermore, restorative adhesive complexes should form a ÒmonoblockÓ to ensure long-lasting restorations (Schwartz & Robbins, 2004;Tay & Pashley, 2007).…”

Correlations between fracture load of zirconia implant supported single crowns and mechanical properties of restorative material and cement

“…In the same study no difference was found in fracture load values between different cementation processes for zirconia 13) . The influence of the cementation mode on lithium disilicate is controversially discussed 12,13) . In the present study an increase in fracture load was found for lithium disilicate, feldspar ceramic and polymer-infiltrated ceramic depending on the compressive strength of the cement.…”

“…To predict clinical behavior of restorations, fracture load tests on crowns are performed although their significance is controversially discussed [9][10][11][12][13][14][15] . Due to differences in test set up, fracture load of restorative materials can vary significantly [10][11][12][13][14][15] .…”

“…Due to differences in test set up, fracture load of restorative materials can vary significantly [10][11][12][13][14][15] . Parameters such as crown design, core material, preparation form, loading angle as well as cementation procedures influence fracture load values.…”

Influence of cementation and cement type on the fracture load testing methodology of anterior crowns made of different materials

“…Currently, the restorations for fracture load tests are differently cemented in various studies [1][2][3][4] . Zinc oxide-phosphate, glass ionomer or adhesive cements are used [1][2][3][4][5][6][7][8] . Zirconia shows high values of flexural strength 9) ; lithium disilicate exhibits lower flexural strength than zirconia 10) .…”
