Abstract
After scientific verification of osteointegration of dental implant, the overall efficiency of dental implant could be accepted. Nowadays, implants take part in a major trend of clinical coverage of edentulous mandible, and in the prosthetic maintenance equipment for partial edentulous mandible patient. For a successful maintenance of implant for a long term, careful mechanical considerations must be provided so that maximum stress in mandible resulted from the chewing force is maintained under the critical value. This study focuses on the reduction of maximum stresses in implanted mandible, especially in cortical bone. The stresses in implant and mandible are analyzed using the finite element packages, such as I-DEAS and NISA II/DISPLAY III using local zooming technique for concentrated stress analysis. We checked von-Mises stress and principle stress in mandible to find out best combination.
