چکیده

Dental implants are being used to retain and support fixed and removable dental prostheses. Over the past several decades, dental rehabilitation with implants has been widely accepted by dentists and patients because of its reliable functional and aesthetic results. In many clinical situations, local bone morphology requires dental implants that have a diameter that is significantly smaller than the typical implant diameters. In these cases, the fatigue life of the smaller diameter implants becomes a critical therapeutic parameter. According to particular situation of 2nd tooth that has low space and also height limitation due to the existence of the Sinus and Nerves in maxilla and mandible, respectively, application of various kinds of implant are being limited. This paper investigates the biomechanical behavior of a threaded dental implant/ surrounding bone system under static and harmonic occlusal forces by using a three-dimensional finite element method for achieving the optimum diameter and length as the most effective parameters affecting stress distribution in surrounding bones. The objective of this research was to predict the fatigue life of 34 different commercial dental implants by considering the variability in diameter and length and material of implants and bone quality for missing upper/lower lateral incisor dental position by 3D finite element method. The influence of the length and diameter is being considered after applying static, dynamic, fatigue loading for evaluation local/cycle failure probabilities in Biodenta, CMI, DIO, Implantium, and Nobel implant systems. In this study, static dynamic and fatigue behaviors of the implant are being investigated.
