To evaluate the clinical and radiographic outcomes of endoscope-assisted maxillary sinus floor elevation with platelet-rich fibrin grafting and simultaneous implant placement (PESS) in atrophic maxillae.
Twenty-three implants were placed to rehabilitate atrophic maxillae. Patient satisfaction was measured with a visual analog scale (VAS). CBCT was taken to assess the bone changes for the elevated sites.
Twenty-two of 23 implants fulfilling the survival criteria represented a 1-year survival rate of 95.65%. The VAS score decreased with time. The residual bone height was 4.45 ± 1.44 mm. The elevation height was 6.72 ± 1.84 mm. The definitive restoration was completed in the 4th month postsurgery. The peri-implant bone level value was 6.04 ± 2.30 mm, 6.32 ± 2.25 mm, and 6.71 ± 1.97 mm at the 3rd, 9th, and 15th month postsurgery. The crestal bone level value decreased by 0.22 ± 0.56 mm from the 3rd month to the 15th month postsurgery (P > .05). Bone mineral density increased with time at the neck, middle, and root site of implant.
PESS in the maxilla resulted in predictable peri-implant bone formation. This strategy is a relatively safe and effective approach with less invasion, which provides new insights into the choice of implant treatment plans.
评估富血小板纤维蛋白（PRF）引导上颌窦底提升同期种植的临床和影像学效果。
为了修复上颌骨萎缩，共植入 23 枚种植体。采用视觉模拟评分（VAS）评估患者满意度。通过 CBCT 评估提升部位的骨质变化。
23 枚种植体中有 22 枚符合生存标准，1 年生存率为 95.65%。VAS 评分随时间逐渐下降。剩余骨高度为 4.45±1.44mm，提升高度为 6.72±1.84mm。术后 4 个月完成最终修复。术后第 3、9、15 个月时，种植体周围骨水平值分别为 6.04±2.30mm、6.32±2.25mm、6.71±1.97mm。第 3 个月至第 15 个月，种植体颊侧骨吸收量为 0.22±0.56mm（P>.05）。骨密度随时间增加，在种植体颈部、中部和根尖部位均有增加。
上颌窦底提升同期种植具有良好的临床和影像学效果。该方法微创、有效，为种植治疗方案的选择提供了新的思路。
