摘要
目的:观察使用椅旁拔除的自体牙,即刻制备为骨移植材料,用于牙槽嵴骨增量的短期临床效果。方法:拔除患者因龋坏或牙周病无法保留的废弃牙、阻生牙,在椅旁即刻制备为粉状或块状骨移植材料,用于重建缺损牙槽嵴,同期或延期植入种植体。二期手术及种植修复完成后对治疗的预后,影像学检查和种植体存留率进行评估。结果:临床观察显示所有病例骨增量区创口愈合良好,无骨增量相关并发症的发生,全景片及CBCT显示种植体骨结合良好,所有种植体在功能性负载后3~6个月的观察期内无一例失败,种植修复取得了较好的临床效果,存留率100%。结论:椅旁即刻制备的自体牙骨移植材料,成骨效果良好,可用于牙槽嵴骨缺损的重建,有望成为继自体骨和人工骨移植材料之后,又一种新型骨替代材料。
Objectives:To evaluate the clinical effect of the alveolar ridge augmentation using chair-side prepared autogenous tooth bone graft material.Methods:Patients were treated with tooth extraction for the failure of endodontic or periodontal treatment and impacted teeth.Massive or powdery bone graft materials,which were rapidly prepared from the teeth by chair-side,were used to repair alveolar bone defects and perform immediate or delayed implant.Prognosis,radiographic examinations and implant survival rate were assessed after the second surgical stage and implant restoration.Results:All wounds healed well without any complications in augmentation zones.Favorable osseointegration can be observed from panoramic radiographs and CBCT.During the 3-6 months follow-up after functional loading,all implants reach the criteria of success(100%survival rate),and achieve a good clinical effect.Conclusion:Autogenous tooth bone graft material which was prepared rapidly by chair-side showed a satisfactory osteogenesis ability and can be applied in alveolar ridge reconstruction.Consequently,this material has the potential to becoming one of the options for a bone substitute like autogenous and allogenous bone grafts in implant dentistry.
