Biomechanics of the human canine pillar based on its geometry using finite element analysis

Int. j. morphol; 32 (1), 2014
This study evaluated the stress distribution based on the canine pillar geometry in human skull, using a finite element analysis. Computed tomography of human skull was used to build a finite element model, which was composed by all bony structures of canine pillar: canine eminence, canine fossa, frontal...

Comportamento biomecânico do sistema prótese/implante em região anterior de maxila: análise pelo método de ciclagem mecânica

Introdução : O adequado posicionamento tridimensional dos implantes é indispensável para garantir a previsibilidade no tratamento com implantes dentários. Objetivo : Analisar comparativamente o comportamento mecânico do sistema prótese/implante em região anterior de maxila, diferindo os sistemas ...

Shear Bond Strength of Acrylic Teeth to Heat-curing Denture Base Resin under Different Disinfectant Methods

The aim of this study was to evaluate the shear bond strength between acrylic teeth and heat-activated acrylic denture base resin using five different disinfectants solutions after simple immersion or under ultrasonic cleaner action. A total of 144 acrylic denture resin specimens were produced with both ...

Effect of endodontic sealer and resin luting strategies on pull-out bond strength of glass fiber posts to dentin

Acta odontol. latinoam; 23 (3), 2010
The aim of this study was to evaluate the influence of eugenolcontaining endodontic sealers and luting strategy on the pull-out bond strength of glass fiber posts to dentin. Sixty-four bovine incisors were randomly assigned into two groups of 32 specimens each for obturation procedure with gutta-percha o...

Influence of ridge type on mandibular distal extension removable partial denture

Acta odontol. latinoam; 23 (1), 2010
The aim of this study was to use photoelastic models to analyze the distribution of stress caused by the incidence of loads on a mandibular distal extension removable partial denture, both on the abutment teeth and on differently shaped residual ridges: distal ascending, descending-ascending, horizontal ...

Análise do stress nas situações de vida diária e do pré-operatório imediato de pacientes cirúrgicos urológicos

Esta pesquisa analisa o stress de 100 pacientes da especialidade cirúrgica urológica, nas situações de vida diária e do pré-operatório imediato, internados em três Hospitais Gerais do Município de São Paulo, Brasil. A coleta de dados foi realizada por meio de um instrumento constituído pelo re...
