Abstract:
Objective:To observe the effect of orbital implant shrink range on the stress distribution in bone-implant interface. Methods:The 3D finite element analysis of craniofacial and orbital implant models with the implant length of 3,4,6 and 10 mm,and with the shrink range of0.05,0.1 and 0.15 mm were established respectively.The stress in the bone-implant interface were calculat-ed and analyzed.Results:The stress increased with the increase of implant shrink range.The stress produced by the implant with 0.15 mm shrink range decreased.The stress of the implant of 10 mm was lower than that of other implants with the shrink range of 0.1 and 0.15 mm.Conclusion:The maximal implant shrink range of 0.1 mm in the model can meet the clinical requirements in orbital implant planning.
