摘　　要：目的　报告自行研制的MS 1型下颌骨骨牵引延长器的结构特点及在颌面骨延长动物实验中的应用效果。方法　采用自行研制的MS 1型内置式下颌骨骨牵引延长器 ,对 15只犬分别进行下颌骨单侧及双侧骨牵引延长实验 ,X线定期检查。结果　下颌骨牵引延长 (2 0± 0 .5 )mm ,达到预设值 98% ,牵引完成后经 5周固定 ,新骨完全骨化。结论　MS 1型内置式下颌骨骨牵引延长器在下颌骨牵引延长中具有明显的实用价值 。Objective To introduce the progressing history of DO technique,and report the characteristics of the home made type MS 1 internal mandibular distracter,and the effects of application of it in animal experiment.Methods 15 Mongrel dogs were subjected to be lengthened of the unilateral or bilateral mandibles using the home made type MS 1 mandibular distracter,and the regular X ray examinations were made.Results About (20±5)mm in length of the mandible had been achieved by the DO(distraction of osteogenesis)technique using the device.The accuracy of the distracter on lengthening would be attained to 98% of the expectancy.The mineralization of the new bone fulfilled the gap zone about 5 weeks after the distraction had been finished during the consolidation period.Conclusion The MS 1 type internal mandibular lengthening device has its special advantages on application of cranio maxillofacial surgery with a great expectancy.
