摘 要：目的：本研讨旨在讨论种植体支抗受正畸力力系作用后的波动性,骨组织的反应及骨代谢的状况。办法：选用15只成年狗随机等量分为三组。G1组为水平力组，G2组为垂直力组，G3组为水平力+垂直力组。在狗的下颌骨种入Bra。nemark纯钛种植体，9周后施力，G1、G2组加力时间6周，G3组水平力作用时间6周，垂直力作用时间6周。辨别进行临床肉眼察看及X线检查，同时进行放射性核元素骨显象，实验完毕后宰杀动物，取标本送组织学检查。后果：①种植体受力后无挪动；②X光线检查种植体一骨界面结合良好，到达骨性结合；③放射性核元素骨显象显示骨代谢活泼，在种植四周只需以成熟的成骨细胞为主。结论：种植体一骨界面能到达骨性结合，遭到正畸力系作用下，可以提供足够的支抗。
Study Stability and Osseous Reaction of Implant Anchorage after Received Orthodontic Force
Abstract：Objective： Discuss stability,osseous reaction and metabolizability of implant anchorage affter received orthodontic force.Methods： 15 adult dogs were divided into 3 groups random. G1 is horizontal force group, G2 is vertical force group, G3 is horizontal+ vertical force group . Branemark pure titanium implant were implanted into the dog’s mandibular bone.Force was put on after 9 weeks, the force last 6 weeks for G1 and G2 groups.In G3 group, horizontal and vertical force last 6 weeks vertical severally. Naked eye observe,X-ray examination and osseous radioactive nucleon raster display were performed. After experimentation, the dogs were killed and the samples were sent to histology examination. Results: ①The implants did not move after receiving force. ②X-ray examination showed the interface of implant and bone have good osseointegration. ③ Osseous radioactive nucleon raster display showed active osseous me
