(P>0.05) in terms of bone issue measurement index between 6 to 8 weeks of each group. Group 1 had the most new bone. Conclusion LIPUS has the potential to promote the repair of periodontal bone defect. There-fore the combination of LIPUS and GBR may be more conducive to the repair and regeneration of periodontal
bone defect.

牙周骨缺损是牙槽骨缺失而使部分牙根面与骨膜、牙龈结缔组织相连[1]。它可使牙齿支持组织包括
牙骨质、牙周韧带、牙槽骨丧失,破坏牙龈的功能和形态,甚至导致牙齿松动、脱落[2]。目前治疗牙周
骨缺损的常用方法为引导骨组织再生(guided bone
regeneration,GBR)和引导组织再生(guided tissue
