CGF在上颌窦外提升术中的临床应用效果评价

Clinical Assessment of CGF in the Maxillary Sinus Floor Lift

目的:探讨上颌窦外提升术联合CGF在上颌后牙区种植修复的临床应用效果。方法:收集2011年3月~2016年12月期间120位患者,上颌后牙缺失伴垂直骨高度不足的病例,分别采用上颌窦外提升联合CGF进行骨增量并同期植入种植体169颗和延期种植14颗,术后6~8个月后完成上部修复;其中Straumann种植体136颗,Bego种植体33颗,随访3~4年。结果:种植区骨高度增加,种植体与周围骨结合良好,未出现松动脱落,临床效果满意。结论:侧壁开窗上颌窦外提升联合CGF同期植入种植体,CGF具有促进新骨形成和种植体骨结合的能力.是种植骨增量的可靠辅助技术。

Objective：To study the clinical effect of maxillary sinus floor lift with CGF in the posterior maxillary region after implant restoration.Methods：After maxillary sinus floor lift,120 cases were collected during March2013 to December 2016,whose vertical bone height was insufficient.The maxillary sinus floor lift with CGF was used to promote bone height.169 implants were implanted simultaneously and 14 cases were delayed.The upper restorations were completed after 6 to 8 months.The numbers of Straumann and Bego implants are 136 and 33,respectively.All cases were followed up for 3 to 4 years.Results：Bone height was increased in the posterior maxillary region.The implants achieved good osseointergration.No implant was loose or falling down.Clinical effect was satisfied.Conclusion：Sinus floor elevation with CGF and simultaneously implantation achieved remarkable clinical effectiveness in the posterior maxillary region.CGF could promote new bone formation,and could be a reliable auxiliary technology for bone augmentation.
