Design Equations for Mixed-Mode Fracture of Dental Ceramic–Cement Interfaces Using the Brazil-Nut-Sandwich Test
(2021-10-01)
Dental interfaces are subject to mixed-mode loading. This study provides practical guidance for determining interfacial fracture toughness of dental ceramic systems. We address interfacial fracture of a composite resin ...
Influence of Ferrule, Post System, and Length on Biomechanical Behavior of Endodontically Treated Anterior Teeth
(Elsevier Science IncNew YorkEUA, 2014)
Effect of occlusal anatomy of CAD/CAM feldspathic posterior crowns in the stress concentration and fracture load
(2021-01-01)
Objectives: This study evaluated the effect of restoration occlusal design on the maximum fracture load and stress distribution of a feldspathic ceramic crown. Materials and Methods: Twenty dentin analogues were used to ...
Influence of occlusal anatomy on acrylic resin CAD/CAM crowns fracture load and stress distribution
(2021-05-11)
Objectives: This study compared the influence of occlusal anatomy on acrylic CAD/CAM crowns fracture load and stress distribution. The null hypothesis was that there would be no difference between the provisional crowns ...
Fractal characterization of brittle fracture in ceramics under mode I stress loading
(Elsevier B.V. Sa, 2010-07-15)
The self-affine behavior of Brazilian disk test titanium oxide specimens for K(Ic) measurement was investigated from 3D elevation maps obtained at regular intervals following crack extension. The bifractal approach could ...
Fracture resistance of roots prosthetically restored with intra-radicular posts of different lengths
(Wiley-blackwell Publishing, IncMaldenEUA, 2010)
Finite element analysis and fracture resistance testing of a new intraradicular post
(Univ Sao Paulo Fac Odontologia BauruBauru-spBrasil, 2012)
Fracture resistance and stress distribution of weakened teeth reinforced with a bundled glass fiber–reinforced resin post
(2022-02-01)
Objectives: To make an in vitro assessment of fracture resistance of weakened and non-weakened teeth receiving intraradicular reinforcement using Rebilda bundled glass fiber–reinforced composite posts (GT), Rebilda ...
