摘要
目的探讨上颌窦内提升术植骨与不植骨对种植体骨整合的影响及两者之间的差异。方法将120枚需要进行内提升手术的种植体随机平均分为两组,第一组60枚为实验组,在上颌窦内提升后植入骨材料同期植入种植体;第二组60枚为对照组,上颌窦内提升后不植骨同期植入种植体。对两组种植体进行临床追踪(平均18个月),观察种植体骨整合、临床检查指标、种植体存留率及影像学变化。结果仅有1例种植体覆盖螺丝暴露,种植体颈部出现骨吸收。所有两组种植体均能完成修复,种植体存留率达到100%,无1例脱落。种植体均能正常行使咀嚼功能,骨整合良好。影像学检查种植体周围均有新骨生长,骨整合良好。结论上颌窦内提升术后不植骨可以取得与植骨同样的效果,可以明显减少患者的种植牙费用,是一种值得推广应用的手术方法。
Objective To investigate the effect of bone grafting on osseointegration of dental implant during maxillary sinus augmentation. Methods One hundred and twenty implants with maxillary sinus augmentation were divided into two groups. The experimental group included 60 implants which were placed simultaneously after osteotome sinus floor elevation with bone grafting; the control group（also 60 implants） otherwise without bone grafting. Implant osseointegration, clinical parameters, the implant survival rate and radiological finding of all implants were estimated after clinical tracking（average 18 months）. Results Only one implant with its cover screw exposed and bone absorption in its neck was observed. All the implants were completed with the prosthetic rehabilitation. The implant survival rate was 100% and no implant lost. Efficient mastication and good osseointegration were obtained by all implants and new bone regeneration around implant was found by radiological examination.Conclusion The similar result of implant osseointegration was observed in the case of osteotome sinus floor elevation with or without bone grafting. Osteotome sinus floor elevation without bone grafting can largely reduce the cost of the patient and would be worth to recommend.
