This study evaluated the clinical and radiographic outcome of implants placed in the posterior maxilla with the osteotome sinus floor elevation (OSFE) technique without graft material.
Twenty-seven 4.1-mm-diameter dental implants (Straumann AG, Basel, Switzerland) were placed to 17 sinuses with residual bone height of ≤ 10 mm and ≥ 5 mm to rehabilitate 23 molar and 4 premolar sites. Implants were simultaneously placed with the OSFE procedure without graft material.
All implants were successfully integrated after 8-12 weeks healing time. At the 2-year follow-up, all the implants presented the survival criteria proposed by Buser et al. and Cochran et al.
The OSFE technique without grafting material may be predictable because the success rate was 100% in this study. Implants gained endo-sinus bone despite the lack of graft material. More patients and longer follow-up are needed to validate the results of this pilot study.
本研究评估了采用骨凿上颌窦底提升（OSFE）技术且不使用植骨材料在上颌骨后部植入种植体的临床和影像学结果。
将27枚直径4.1毫米的牙科种植体（瑞士巴塞尔的士卓曼公司）植入17个剩余骨高度≤10毫米且≥5毫米的上颌窦，以修复23个磨牙位点和4个前磨牙位点。种植体在不使用植骨材料的情况下与OSFE手术同时植入。
经过8至12周的愈合时间，所有种植体均成功整合。在2年的随访中，所有种植体均符合Buser等人和Cochran等人提出的存活标准。
不使用植骨材料的OSFE技术可能具有可预测性，因为在本研究中成功率为100%。尽管没有植骨材料，种植体仍获得了窦内骨。需要更多患者和更长时间的随访来验证这项初步研究的结果。
