Abstract:
Objective:To observe the effects of orbital bone density on the stress distribution of implant-bone surface.Methods:The 3D finite element analysis craniofacial model with eight HU values(300 -1 0 000)was established.A force of 20 N along the im-plant axis was applied on the model.The stress values and distribution were calculated and analyzed.Results:The peak of stress val-ue and displacement discreased as HU value increased.In the range of HU value 800 -1 000 HU,the peak of stress value and dis-placement of bone interface did not significantly change with the increasing of HU value.Conclusion:Orbital bone density is an im-portant factor on orbital implant failure when HU value below 800.
