摘　　要：目的:设计研制一种用于下颌骨的新型种植型骨牵张器。方法:采用国际标准的钛合金材料按照生物力学原理设计机械加工制成,植入山羊的下颌骨完成牵张实验。结果:山羊的下颌骨成功延长15 mm,牵张器稳定性良好。结论:该牵张器结构轻巧、操作简便,克服了以往牵张器的不足,具有较高的临床应用价值。Objective： This study wanted to design a new distraction osteogenesis apparatus made of titanium in mandible distraction. Methods ： The new distraction apparatus was designed on the basis of biomechanics theory and inferior edge of goat mandible was prepared for implantation. After vertically osteotomy two implant -distraction devices were applied, Resuits： The bone segment was augmented 15 mm successfully, The newly distraction apparatus was stable almost in every experiment study. Conclusion： The newly distraction apparatus can bear the forces and function well in the distraction osteogenesis test,
