目的 探讨自体骨碎屑混合Bio-Oss骨代用品用于侧壁开窗上颌窦底提升术同期牙种植体植入的临床效果. 方法 选择2013年1月—2014年6月于解放军62医院口腔科就诊的牙列缺损患者28例,利用种植机于阻生下颌第3磨牙制备合适足量的骨碎屑,与Bio-Oss骨代用品混合植入提升上颌窦底,侧壁开窗区表面覆盖Bio-Gide可吸收胶原膜,种植体同期植入. 观察种植效果. 结果 本组28例共植入32枚种植体,均获得骨结合,种植体无松动脱落. 所有病例完成修复后随访6个月,修复效果满意. 结论 Bio-Oss骨代用品混合自体骨碎屑移植在开窗法上颌窦底提升同期牙种植体植入术中临床效果良好.%Objective To investigate the effect of bone rubbish autotransplantation combined with Bio-Oss bone substitutes in implantation of maxillary sinus lift and simultaneous dental implantation. Methods A total of 28 patients with dentition defect during January 2013 and June 2014 were recruited in this study. The ample numbers of bone rubbish were obtained using bone block of mandibular third molar region, and then were combined with Bio-Oss bone substitutes in implantation of maxillary sinus floor for lifting. Bio-Gide adsorbable collagenous membrane covered the surface of side windowing area with simultaneous implantation. The effect of implantation was observed. Results A total of 32 implants were obtained in the 28 patients, and synostosis was performed for all implants without loosening or shedding. All the pa-tients were followed up for 6 months with satisfactory effect. Conclusion The bio-oss bone substitutes combined with bone rubbish autotransplantation in implantation of maxillary sinus lift and simultaneous dental implantation can achieve good effect.
