This study aimed to evaluate factors related to new bone formation (NBF) following simultaneous implant placement with transcrestal sinus floor elevation (TSFE).
Between 2008 and 2020, 357 implants (276 patients) were placed with TSFE. Clinical and radiographic examinations were performed at the preoperative, postoperative, restoration, and follow-up stages. Marginal bone loss, during healing, and the survival rate were retrospectively analyzed.
Implant protrusion lengths (IPL: 3-5 mm) significantly influenced NBF during the healing period (P-value = 0.026, Odds Ratio = 1.15, 95% confidence interval = 1.02- 1.30). Bone grafting was correlated with NBF (P-value = 0.001). The distance between the implant and lateral wall of the sinus (mesial: P-value = 0.041, distal: P-value = 0.019, buccal: P-value = 0.032, lingual: P-value = 0.043) and angle between the implant and sinus floor significantly influenced NBF in four directions (mesial: P-value = 0.041, distal: P-value = 0.02, buccal: P-value = 0.047, lingual: P-value = 0.005). Implant shape (cylindrical or conical), perforations, smoking, and diabetes did not significantly affect NBF during the healing period (P > 0.05).
Increasing the distance and angle between the implant and lateral wall of the sinus floor corresponded with reduced NBF. IPL may be an important factor that should be considered.
Our study analyzed new bone formation following transcrestal sinus floor elevation among patients who underwent this procedure with simultaneous implant placement, several factors (including angle and distance between sinus and lateral wall and implant protrusion length) were included in our study.
本研究旨在评估经牙槽嵴顶提升（TSFE）同期种植体植入后新骨形成（NBF）的相关因素。
2008 年至 2020 年间，357 枚种植体（276 例患者）采用 TSFE 植入。在术前、术后、修复和随访阶段进行临床和影像学检查。回顾性分析边缘骨吸收、愈合期和存活率。
种植体突出长度（IPL：3-5mm）在愈合期显著影响 NBF（P 值=0.026，优势比=1.15，95%置信区间=1.02-1.30）。植骨与 NBF 相关（P 值=0.001）。种植体与窦侧壁的距离（近中：P 值=0.041，远中：P 值=0.019，颊侧：P 值=0.032，舌侧：P 值=0.043）和种植体与窦底的角度显著影响四个方向的 NBF（近中：P 值=0.041，远中：P 值=0.02，颊侧：P 值=0.047，舌侧：P 值=0.005）。种植体形状（圆柱形或圆锥形）、穿孔、吸烟和糖尿病在愈合期对 NBF 无显著影响（P>0.05）。
增加种植体与窦侧壁的距离和角度与 NBF 减少相关。IPL 可能是一个重要的需要考虑的因素。
本研究分析了经牙槽嵴顶提升术同期种植体植入后患者的新骨形成情况，包括角度和距离等因素（包括窦与侧壁和种植体突出长度之间的角度和距离）。
