A 3D-FE Stress Analysis of Complete Mandibular Fixed Prosthesis and the Supporting Bone──Comparative Stress Analysis with Different Depth of Implant in the Bone
In this study a three dimensional finite element model of complete implant-supPOrted fixed prosthesis of the mandible was developed aided by CT scan and ANSYS software.Stress analysis was made with different depth of screw-type implants in the front region of the mandible that the implants were deep into the cortex of lower border or not.Results showed depth Of implantation greatly influenced the periimplant bone stress.Making the implants deep into lower bonier cortex could make stress transfer more evenl...
