下颌骨节段截除后修复的方法较多。用钛板修复下颌骨具有较好的生物稳定性、不腐蚀性和合适的强度,故手术效果较佳。近来人们越来越多地关注到牙槽嵴的恢复,因为良好的牙槽嵴对托牙安装及功能和形态的恢复至关重要。作者在下颌骨节段截除后立即用纯肽板和自体髂骨块修复,术后6个月应用羟基磷灰石(HA)和骨髓颗粒松质骨(PLBM)混合植入物置于 There are many ways to repair the mandibular segment after it is cut off. Restoration of the mandible with titanium plate has good biological stability, non-corrosive and appropriate strength, so the operation effect is better. Recently, people pay more and more attention to the restoration of alveolar ridge, because good alveolar ridge is very important to the installation of denture and the recovery of function and morphology. The authors were repaired with pure peptide and autologous iliac bone immediately after amputation of the mandibular segment. Six months after application, hydroxyapatite (HA) and bone marrow mixed with cancellous bone (PLBM) were implanted
