要約

Dental implants have been increasingly used to recover the masticatory function of lost teeth. Computer prediction of failure in dental implants has been common in recent years. The finite element analysis was reported to simulate biomechanical problems with complex geometries. Our research describes a numerical study performed with the 3D finite element method of effects of dental implants on biomechanical behaviour of masticatory system. Mandibular bones with natural teeth were redesigned and two dental implant systems were restored in molar region by using computer tomography scan pictures and Computer Aided Design tools. The goal was to evaluate the stress distribution in the bone surrounding these implants under combined static loading cases by using the ABAQUS program. Stress was maximal around the top of the implant, highest in the cortical bone at the neck of the implant, and lowest in the cancellous bone. Hence, the implanted bone area should be preserved clinically in order to maintain the functionality of the bone–implant interface.
