骨牵张成形术(distraction osteogenesis)是近年来才发展起来的一种用于骨增长的方法,尤其在正颌领域中,无论是实验还是临床中,这种技术已在管状骨延长方面得以大量应用。但以往在管状骨的应用中多以穿皮骨内钉作为抗基,而上颌骨无论在来源还是结构上均有别于管状骨,骨内钉无法在上颌骨薄弱骨段上取得坚强固位,故一直未有上颌骨牵张成形的临床文献报道。本研究试图利用骨牵张成形装置及骨结合种
Distraction osteogenesis is a method developed for bone growth in recent years. Especially in the field of orthognathic surgery, this technique has been widely used in the treatment of tubular bone elongation in both experimental and clinical settings application. However, in the past in the application of tubular bone to wear more than the endocervical nail as an anti-base, while the maxillary bone in both the source and the structure are different from the tubular bone, intramedullary nail in the maxilla weak bone segment can not get strong retention , So there has been no clinical literature on maxillary distraction. This study attempts to make use of bone distraction devices and bone-associated species
