ABSTRACT
Introduction: Dental implants should transmit stresses to the bone tissue and generate strain levels that favor the balance between the bone formation and bone resorption processes. Due to the high number of patients with reduced jawbone dimensions, it is essential to study the biomechanical behavior of short dental implants.
Objective: Evaluate the effect of the design parameters: Maximum diameter, Length of the bone-implant interface and Thread depth on the biomechanical behavior of a new design of short dental implant.
Methods: The 3D models of the short dental implant were created using Autodesk Inventor Professional software (Autodesk Inc, California, USA) and analyzed by finite elements with Autodesk
® Algor
® Simulation software (Autodesk Inc, California, USA).
Results: The maximum von Mises equivalent stress was obtained in peri-implant cortical bone. The loads applied to the implant generated in peri-implant cancellous bone, the highest von Mises equivalent stress in the lower end of the apical region and the lowest stress values in the region next to the cortical bone. In addition, the highest strain values were obtained in cancellous bone for all models under study.
Conclusions: In general, the simulation results showed that most of the models under study generate stresses and strains in peri-implant cortical bone at levels that stimulate bone growth and bone remodeling. However, for some models, it was observed levels of stress and strain in peri-implant cancellous bone that could provoke the bone onset. The variables Implant diameter and Thread depth exhibited the greatest influence on the maximum stresses and strains obtained in the bone tissue.
