Comparative analysis of stress distribution in one-piece and two-piece implants with narrow and extra-narrow diameters: A finite element study.

Objectives: The aim of this in vitro study was to evaluate the stress distribution on three implant models with narrow and extra-narrow diameters using the finite element method (FEA).

Materials And Methods: Dental implants of extra-narrow diameter of 2.5 mm for a one-piece implant (group G1), a narrow diameter of 3.

A Finite Element Analysis to Compare Stress Distribution on Extra-Short Implants with Two Different Internal Connections.

Background: The goal of this study was to analyze the stress distribution on two types of extra-short dental implants with 5 mm of length: An internal hexagon (IH) and morse taper connection (MT).

Methods: The three-dimensional model was composed of trabecular and cortical bone, a crown, an extra-short dental implant and their components. An axial load of 150 N was applied and another inclined 30° with the same magnitude.

Photoelastic stress analysis surrounding different implant designs under simulated static loading.

Objective: The proposal of this study was to use a photoelasticity method to analyze the stress dissipation in the bone surrounding an implant under simulated loading.

Materials And Methods: Four implant systems with different internal connection designs were studied: conical connection (group 1), triangular connection (group 2), Morse taper (group 3), and internal hexagon (group 4). After the models' inclusion in a photoelastic resin, they were subjected to static loads of 100, 150, and 200 N.
