摘要
目的：探讨上颌后牙区即刻种植及同期上颌窦内提升的临床效果。方法：选择上颌后牙区即刻种植病例57例,其中上颌后牙区上颌窦底骨高度为（3.2±0.6）mm,微创拔除患牙后,行单纯上颌窦内提升同期牙种植术,植入德国XIve种植体21枚,德国Ankylos种植体45枚,种植体与拔牙窝骨壁之间的间隙植入自体骨或人工骨代用品,缝合固定胶原塞以关闭拔牙窝。种植手术后至少5-6个月完成永久修复,随访6-24个月。结果：临床随访期内种植体存留率100%,57例患者上颌窦底提升高度3-5 mm。66枚种植体成功负载,种植体稳定,骨结合状况良好。57例患者均达到良好的临床和放射学上的骨结合并成功负载。结论：上颌后牙区即刻种植及上颌窦内提升术不仅能有效治疗上颌窦底牙槽骨高度不足的上颌后牙区,而且缩短治疗过程,简化手术操作,获得较为理想的临床效果。
Objective：To investigate the clinical application of immediate implantation in maxillary posterior region and simultaneous maxillary sinus elevation. Method：Select 57 patients undergoing immediate implantation in maxillary posterior region,with the height of（3.2±0.6）mm in maxillary sinus floor. For the patients,simple internal sinus lift with simultaneous implant placements were performed after minimally invasive diseased teeth extractions,in which 21 German XIve implants and 45 German Ankylos implants were implanted. In the gaps between implants and extraction socket bone walls,autogenous bones and artificial bone substitutes were implanted,and collagen plugs were securely sutured to close extraction sockets. Permanent dental restorations were completed at least 5-6 months after implantation,and 6-24 months clinical follows up were performed. Result：During the clinical follow up,the implant survival rate was 100 %. In 57 patients,maxillary sinus floors height have elevated for 3 -5mm;66 implants was successfully loaded,with stable implants,good condition in synosteosis and without adverse subjective symptoms. All of the 57 patients had achieved good synosteosis and success loads clinically and radiologically. Conclusion：By immediate implantation in maxillary posterior region and simultaneous maxillary sinus elevation,not only the maxillary posterior region with inadequate height in maxillary sinus floor alveolar bone can be treated but also the shortened treatment course,simplified operative procedure can be achieved,so that the clinical results are more satisfactory.
