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.
