A morphometric and biomechanic comparison of titanium implants inserted in rabbit cortical and cancellous bone.

摘要: The removal torques for screw-shaped pure titanium implants inserted in rabbit tibia and the femoral part of knee joint tissue response to these implants, as quantitated with light microscopic morphometry on ground sections, were compared after 6 weeks, 3 months, months. bone surrounding intra-articular was mostly cancellous, while cortical formed around tibial implants. torque needed remove increased time, but there no such increase At significantly less spite fact that more found threads When calculating amount situated subchondral passage, which corresponded higher torque. Additional observations unscrewed 12 months indicated rupture occurred between implant surface calcified bone. Findings indicate resistance unscrewing is dependent compact a implant.
