Three dimensional finite element analysis for the effects of bone cortical thickness on the stress distribution of implant bone interface
Abstract：Objective To investigate the effects of bone cortical thickness on the Von-Mises stress distribution of implant bone interface by three dimensional finite element analysis.Methods The mandible three dimensional finite element models containing implant were established by three dimensional computer-aided designing (CAD) software to analyze the effects of different bone types on Von-Mises stress distribution of implant bone interface.Results Regardless of the size of implant,bone cortex thickness became thinner with the changes of mandible sclerotin types,and elastic modulus of cancellous bone was decreased,however, the innerstress of mandible and implant was increased.Conclusion The mandible sclerotin types have important effects on stress distribution of implant and surrounding bone,moreover, bone typeⅡis superior to bone type Ⅲ in successful repairing of implant.
