摘要
目的 :下颌骨缺损自体骨移植术后采用种植义齿修复。方法 :6例髂骨移植患者 ,3例直接植入种植体 ;2例经颌骨骨块上置法植骨后植入种植体 ;1例经牵引成骨术增高牙槽突后植入种植体。2例腓骨移植患者 ,分别经腓骨上置法移植和牵引成骨术增高牙槽突后植入种植体。结果 :8例患者最终都植入种植体 ,其中3例已完成上部义齿修复。结论 :下颌骨缺损自体骨移植术后 ,常有牙槽突骨量不足 ,需行牙槽突II期重建。
Objective:Implants were applied to rehabilitate the masticatory function of patients with autografts for their mandibular defects.Methods:Six patients with nonvascular iliac bonegrafts and two patients with vascuˉlar fibular bonegrafts were included in this study.Among them,3patients with iliac bonegrafts were inserted implants directly,2patients with iliac bonegrafts were onlaygrafted with automandibular bone atthe mesial trianˉgular bone-defects and inserted implants at the same time,another patient with iliac bonegraft was augmented by distraction osteogenesis for her low level of alveolar process and secondarily inserted implants.The two paˉtients with fibular bonegrafts were suffered from complete bone-defects of alveolar process,augmented by onˉlay grafted iliac bone and distraction osteogenesis respectively,and finally inserted implants.Results:The eight patients with autografts in mandibular defects were ultimately inserted implants after alveolar process modiˉfied by various surgical technics.Among themthree patients have got their final prosthesis.Conclusions:The volume deficiency of alveolar process was met undoubtedly after autografts in mandibular defects reconstruction.Before inserting implants,alveolar process needs to be reconstructed secondarily.Onlay grafts and distraction osteogenesis could restore the volume of alveolar bone successfully.
