Abstract:
Objective:To design a new elastic implant-distraction apparatus. Methods:The implant-distraction apparatus consists of tow units, a TiNi shape memory alloy spring and an implant, made of pure titanium TA2.Spring was put into the hollow implant.After horizontal osteotomy, the implant-distraction device was placed into the partial edentulous area of mandible of 6 dogs to distract the alveolar bone.Results: The apparatus was manufactured.It could implement continual autodistraction and kept stable in the in vivo experiment. 10 weeks after application of the apparatus the transport bone segment was vertically augmented by 4.7 mm on average.Conclusion: The implant-distraction device is functional in distraction osteogenesis.
