Photoelastic Stress Analysis in Prosthetic Implants of Different Diameters: Mini, Narrow, Standard or Wide [PDF]

Journal of Clinical and Diagnostic Research, 2014
Purpose: This study investigated the biomechanical behavior of screwed partial fixed prosthesis supported by implants with different diameters (2.5 mm; 3.3 mm and 3.75 mm) by using a photoelastic analysis.

Evaluation of effort zones between custom implant sinterized and the prefabricated implant though photoelasticity

Revista Facultad de Odontología Universidad de Antioquia, 2022
Introduction: the use of custom implants is a very common treatment; we assess and compare their behavior against that of conventional implants. This study aimed to make sure that the stress zones of the custom implant are different from those presented ...

Stress distribution in the peri-implant area of pure titanium and titanium-zirconium small implants

Brazilian Journal of Oral Sciences, 2019
Aim: In dental implant treatment, there is a demand for mechanically stronger implants. Despite the existence of several studies showing the clinical success of narrow diameter implants, most of them are based on pure titanium (cpTi) alloys.

FEM and BEM Stress Analysis of Mandibular Bone Surrounding a Dental Implant [PDF]

The Open Mechanical Engineering Journal, 2015
In the present work the structural behaviour of a mandible with a dental implant, considering a unilateral occlusion, is numerically analysed by means of the Finite Element Method (FEM) and the Boundary Element Method (BEM). The mandible, whose CAD model was obtained by computer tomography scans, is considered as completely edentulous and only modelled

Biomechanical evaluation of one-piece and two-piece small-diameter dental implants: In-vitro experimental and three-dimensional finite element analyses

Journal of the Formosan Medical Association, 2016
Small-diameter dental implants are associated with a higher risk of implant failure. This study used both three-dimensional finite-element (FE) simulations and in-vitro experimental tests to analyze the stresses and strains in both the implant and the ...

Stress Analysis of an Endosseus Dental Implant by BEM and FEM [PDF]

The Open Mechanical Engineering Journal, 2012
In this work the Boundary Element Method (BEM) and the Finite Element Method (FEM) have been used for an elastic-static analysis of both a Branemark dental implant and a generic conic threaded implant, modelled either in the complete mandible or in a mandibular segment, under axial and lateral loading conditions. Two different hypotheses are considered
