Numerical assessment of bone remodeling around conventionally and early loaded titanium and titanium–zirconium alloy dental implants

摘要

The aim of this study was to investigate conventionally and early loaded titanium and titanium–zirconium alloy implants by three-dimensional finite element stress analysis. Three-dimensional model of a dental implant was created and a thread area was established as a region of interest in trabecular bone to study a localized part of the global model with a refined mesh. The peri-implant tissues around conventionally loaded (model 1) and early loaded (model 2) implants were implemented and were used to explore principal stresses, displacement values, and equivalent strains in the peri-implant region of titanium and titanium–zirconium implants under static load of 300 N with or without 30° inclination applied on top of the abutment surface.
