Three Dimensional Evaluation of a Dental Implant in Different Angles by Finite Element Method

Introduction: Recently, teeth drawbacks, which account a source of discomfort for people and also decrease self-confident among them, can be correct with dental implants. Objective: In this paper, precise modeling of the various geometric sections for a dental implant (number 5) is performed. Materials and Methods: The rate of loading on the dental implant is variability considered in three angles of 0, 15 and 25 degrees at a time interval of 0 to 1 seconds to apply a force similar to the chewing cycle. By examining the stress and strain patterns in the spongy, components, fixture, spongiform, buccal and lingual bones a model is employed in order to obtain the exact distribution of stress and strain within the bone and the angled abutment. Results: According to the obtained results, the angle of 25 degrees is an ideal model in the dental implant. These results also indicate that the areas around the buccal and lingual neck are more susceptible to damage in the location of the attachment to the fixture. Conclusions: We will see a lot of bone resorption after a long time due to the increase in stress and strain in the compact bones and bone formation. Whereas in spongy bone, unlike compress bone, low stress results in a very high strain that is ideal and declines the bone resorption. The increase of the angle enlarges stress in the fixture that it is important not only for choosing the implant model but also the quality of the implant so that it can withstand high stress.
