下颌骨骨质缺损,可因外伤、肿瘤、感染等所致。为了恢复缺损下颌骨的外形和功能,多年来对植入骨的选择一直是讨论和研究的重点。国内外的临床实践均己证实,选用自体骨并带有较多的松质骨和骨髓,是保证植入骨成功的重要条件。除此之外,也必须有固定植入骨的支架,如自体骨的内板,皮质骨以及金属制成的支托等。1981年4月美国颌面整形外科学术代表团应邀来我校讲学及手术表演。H.G Schwartz等介绍了用涤纶高分子化合物制做的下颌骨外
Mandibular bone defects, due to trauma, cancer, infection and so on. In order to restore the shape and function of the mandibular defect, the choice of implanting bone has been the focus of discussion and research for many years. Clinical practice both at home and abroad have confirmed that the selection of autologous bone with more cancellous bone and bone marrow is an important condition for successful bone implantation. In addition, there must also be a stent that is fixedly implanted in the bone, such as the inner plate of the autologous bone, the cortical bone, the support made of metal, and the like. 1981 April American maxillofacial plastic surgery academic delegation invited to our school lectures and surgical performances.
