这项回顾性研究随访4个月至10年，评价了使用骨凿窦底提升（OSFE）植入种植体（未添加骨移植）的生存率、成功率和并发症发生率。共放置926个种植体，包括530个短种植体（6 mm至8.5 mm）和209个低残留骨高度（RBH）（< 5 mm）种植体。在植入种植体后约3个月、1年、3年和5年，在某些情况下长达10年，对骨水平进行评价。5年随访时，种植体存活率为98.3%。926个种植体中有12个失败（6个假体前，6个假体后）。对于联合系统（Straumann; Nobel Biocare），骨丢失阈值小于1 mm时，成功率为95.4%。短种植体的存活率和成功率在统计学上与常规长度种植体相当。低RBH种植体的存活率较低，但可接受，为95.7%。不良事件罕见，报告了1例感染和0例眩晕。本研究的结果表明，即使在低RBH中使用短种植体，使用OSFE植入种植体而不添加骨移植物也是非常成功的。
This retrospective study with a follow-up period of 4 months to 10 years evaluated survival, success, and complication rates of implants placed using osteotome sinus floor elevation (OSFE) without added bone grafting. A total of 926 implants were placed, including 530 short implants (6 mm to 8.5 mm) and 209 implants in low residual bone height (RBH) (< 5 mm). Bone levels were evaluated at approximately 3 months and at 1, 3, and 5 years, and in some cases up to 10 years after implants were placed. The implant survival rate was 98.3% at the 5-year follow-up. Twelve of the 926 implants failed (6 preprosthetic, 6 postprosthetic). The success rate was 95.4% at a threshold of less than 1 mm of bone loss for combined systems (Straumann; Nobel Biocare). Short implant survival and success rates were statistically comparable to conventional-length implants. Low-RBH implants had a lower but acceptable survival rate of 95.7%. Adverse events were rare, with one case of infection and zero cases of vertigo reported. The findings of this study indicate that implant placement with OSFE without added bone graft is highly successful, even when short implants are used in low RBH.
