A influência do alagamento apical na distribuição de tensões em canais radiculares curvos: análise de elementos finitos
(Universidade Federal de Santa MariaBROdontologiaUFSMPrograma de Pós-Graduação em Ciências Odontológicas, 2013-08-15)
Localized irregularities in the canal walls are sities which concentrate stresses and make the stresses distribution occurs asymmetrically in the root structure during the filling phase. This asymmetric distribution of ...
Predicting Posttraumatic Stress Symptom Prevalence and Local Distribution after an Earthquake with Scarce Data
(2017)
After a major earthquake, the assignment of scarce mental health emergency personnel to different geographic areas is crucial to the effective management of the crisis. The scarce information that is available in the ...
Stress distribution around implants with abutments of different materials: A comparison of photoelastic, strain gage and finite element analyses
(2015-01-01)
Objective: To compare stress transmission around implants with abutments made of three different materials using photoelastic, strain gage (SGA) and finite element (FEA) analyses. Methods: Three abutments - UCLA calcinable, ...
Study of stress distribution with finite element method in a root with prefabricated threaded split shaft post - Part I
(C S R E A Press, 2000-01-01)
A finite element analysis was carried out to study the role of prefabricated threaded split shaft post (Flexi-Post) on dentinal stress in pulpless tooth. Three dimensional plane strain model of mesio-distal section of a ...

Photoelastic Analysis of Stress Distribution With Different Implant Systems
(Allen Press Inc, 2014-04-01)
The aim of this study was to evaluate stress distribution with different implant systems through photoelasticity. Five models were fabricated with photoelastic resin PL-2. Each model was composed of a block of photoelastic ...
Influence of parafunctional loading and prosthetic connection on stress distribution: A 3D finite element analysis
(Elsevier B.V., 2015-11-01)
Statement of problem. Clinicians should consider parafunctional occlusal load when planning treatment. Prosthetic connections can reduce the stress distribution implant-supported prosthesis. Purpose. The purpose of this ...
A general threshold stress hybrid hazard model for lifetime data
(SPRINGERNEW YORK, 2012)
In this paper we propose a hybrid hazard regression model with threshold stress which includes the proportional hazards and the accelerated failure time models as particular cases. To express the behavior of lifetimes the ...
Finite element analysis of the influence of geometry and design of zirconia crowns on stress distribution
(Wiley-Blackwell, 2015-02-01)
Purpose: To evaluate the influence of the geometry and design of prosthetic crown preparations on stress distribution in compression tests, using finite element analysis (FEA). Materials and Methods: Six combinations of ...
