摘要:

［目的］对上颌窦底提升同期植入ITI种植体进行临床评价。［方法］87例上颌后牙缺失患者，其中66例窦底牙槽嵴高6~10 mm者行上颌窦底内提升植骨手术，其余21例骨高2~5 mm者行开窗植骨上颌窦底提升术，均同期植入ITI种植体。手术3~6个月后拍X光曲面全景片，确定骨结合后行上部修复。修复后6~52个月观察评价骨结合情况。［结果］所有患者术后均未出现上颌窦炎症，在98枚种植体中，1枚种植失败，其余97枚种植体稳定，未见明显骨吸收影像。种植体获得了良好的骨结合。［结论］临床上应根据上颌窦底牙槽嵴高度不同，选用开窗植骨或上颌窦内提升技术提升上颌窦底。上颌窦底提升同期植入ITI种植体在临床上是可行的。由于ITI种植体本身的特点，同期植入，可以保证其初期稳定性，利于种植体-骨结合。

Abstract:

［Objective］To study the effect of maxillary sinus floor lifting by bone graft with instant ITI implants placement.［Methods］Eighty-seven patients suffered the loss of up posterior teeth,sixty-six cases whose bone height of maxillary sinus floor was between 6~10 mm underwent internal sinus floor elevation,and other 21 cases whose bone height between 2~5 mm underwent maxillary sinus lift with bone graft.All cases were simultaneously placed implants.The implants were restored 3 to 6 months later by using digital panoramic.Evaluate the osseointegration during a follow-up period of 6 to 52 months.［Results］There were no clinical complaints of maxillary sinusitis for all cases.Only one implant lost in total 98 implants.The rest 97 implants were stable and had well osseointegration on X-ray film.［Conclusion］It is practical to take maxillary sinus lift with bone graft or internal sinus floor elevation with simultaneous placement of implants according to different height of alveolar ridges.Two approaches with bone graft and simultaneous placement of ITI implants show desirable clinical results.
