Stress analysis in dental prosthesis

Dental implant has been used and studied for the replacement of missing teeth for many years. It has been well known that the success of dental implant is heavily dependent on initial stability and long-term osseointegration due to optimal stress distribution in the surrounding bones. In this study, the 3D finite element analysis is used o study the stresses distribution in dental prosthesis under different loading cases. The von Mises stress distribution indicated that stress was maximal around the top of the implant with varying intensities in the different loading cases. The stress was highest in the cortical bone at the neck of implant and lowest in the cancellous bone. © 2010 Elsevier B.V. All rights reserved.
