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 ...
Photoelastic Stress Analysis in Screwed and Cemented Implant-Supported Dentures With External Hexagon Implants
(Lippincott Williams & Wilkins, 2010-07-01)
The aim of this study was to assess the stress distribution of the retention systems (screwed and cemented) for implant-supported fixed partial dentures by means of photoelastic method. Two models were made of photoelastic ...
Residual stresses explaining clinical fractures of bilayer zirconia and lithium disilicate crowns: A VFEM study
(2021-01-01)
Objective: To understand the stress development in porcelain-veneered zirconia (PVZ) and porcelain-veneered lithium disilicate (PVLD) crowns with different veneer/core thickness ratios and cooling rates. To provide design ...

Influence of buccal cusp reduction when using porcelain laminate veneers in premolars. A comparative study using 3-D finite element analysis
(2011-10-01)
Objectives: Based on a maxillary premolar restored with laminate veneer and using the 3-D finite element analysis (FEA) and mCT data, the aim of this study was to evaluate the influence of different types of buccal cusp ...

Comparison of different designs of implant-retained overdentures and fixed full-arch implant-supported prosthesis on stress distribution in edentulous mandible - A computed tomography-based three-dimensional finite element analysis
(2013-04-26)
A finite element analysis was used to compare the effect of different designs of implant-retained overdentures and fixed full-arch implant-supported prosthesis on stress distribution in edentulous mandible. Four models of ...
