Abstract

The aim of this ongoing prospective study was to determine the 36-month survival rate of short porous implants in the posterior maxilla with 2 to 7 mm of initial bone height in 48 patients. Forty-eight implants were placed; 35 were in sites with a bone height of 5 mm or less and 13 patients required sinus elevation with osteotomes in addition to a xenograft. All implants were loaded with single crowns. At the end of the follow-up period the survival rate was 97.92%. The use of short porous implants showed good predictability in the treatment of the posterior maxilla in this interim 3-year report.

摘要

这项正在进行的前瞻性研究的目的是确定48例患者后上颌骨中初始骨高度为2至7毫米的短多孔种植体的36个月存活率。共植入48枚种植体；35枚位于骨高度为5毫米或更低的部位，13例患者除使用异种骨移植外，还需要用骨凿进行窦提升。所有种植体均采用单冠修复。随访期结束时，存活率为97.92%。在这份3年中期报告中，短多孔种植体在治疗后上颌骨方面显示出良好的可预测性。
