Abstract

Objective

This study aimed to compare the clinical effects of implants placed in sites with a transcrestal sinus floor elevation (TSFE) featuring a residual bone height (RBH) of ≤ 5 mm, without Schneiderian membrane perforations, to those in sites where a lateral window approach was utilized to repair perforations that occurred during TSFE.

Methods

A total of 104 implants in 80 patients (80 sinuses) with RBH ≤ 5 mm who had undergone TSFE with simultaneous implant placement were included in this retrospective study. The implants were categorized into two groups based on whether the Schneiderian membrane was perforated, and the lateral window technique for sinus floor elevation (LSFE) was utilized to repair perforations that occurred during the TSFE procedure. The early implant loss, endo-sinus bone gain (ESBG), and implant apical bone resorption (ABR) were used to assess new bone formation between the non-perforated and the perforated groups.

Results

The non-perforation group consisted of 89 implants in 69 patients (69 sinuses), whereas the perforated group included 15 implants in 11 patients (11 sinuses). No early implant loss or postoperative complications were observed in either group during the first 6 months following implant installation. The ESBG was (5.83 ± 2.06) mm for the non-perforation group and (7.76 ± 1.63) mm for the perforation-repaired group (p < 0.001). A linear mixed model indicated that group (β = 2.41, 95% CI = 1.49, 3.33, p < 0.001) and RBH (β = −0.53, 95% CI = −0.80, −0.27, p < 0.001) significantly influenced ESBG. The ABR between the non-perforation and perforated group has no statistically significant difference (β = 0.84, 95% CI = −0.41, 2.08, p = 0.185).

Conclusion

Repairing Schneiderian membrane perforations that occur during TSFE in cases with RBH ≤ 5 mm, using the lateral window technique, leads to ideal internal radiographic bone augmentation volume maintenance in the maxillary sinus compared to cases without perforation; no significant difference in early implant loss was observed.

RBH≤5mm的经瓣窦底抬高的影像学结果：非穿孔和外侧修复病例

目的本研究旨在比较在残余骨高度(RBH)≤5mm且无施耐德膜穿孔的经瓣窦底抬高（TSFE）部位放置种植体与在TSFE期间使用侧窗入路修复穿孔部位放置种植体的临床效果。方法回顾性分析80例RBH≤5 mm患者（80个鼻窦）行TSFE同时植入种植体的104颗种植体。根据施耐德膜是否穿孔将种植体分为两组，使用窦底抬高侧窗技术（LSFE）修复在TSFE过程中发生的穿孔。采用早期种植体损失、窦内骨增重（ESBG）和种植体根尖骨吸收（ABR）来评估未穿孔组和穿孔组之间的新骨形成情况。结果未穿孔组69例（69个鼻窦）共89个种植体，穿孔组11例（11个鼻窦）共15个种植体。在种植体安装后的前6个月内，两组均未观察到早期种植体丢失或术后并发症。未穿孔组ESBG为（5.83±2.06）mm，穿孔修复组ESBG为（7.76±1.63）mm （p < 0.001）。线性混合模型显示，组（β = 2.41, 95% CI = 1.49, 3.33, p < 0.001）和RBH （β = - 0.53, 95% CI = - 0.80, - 0.27, p < 0.001）显著影响ESBG。未穿孔组与穿孔组的ABR差异无统计学意义（β = 0.84, 95% CI = - 0.41, 2.08, p = 0.185）。结论对于RBH≤5mm的TSFE患者，采用侧窗技术修复上颌窦施耐德膜穿孔，与无穿孔的患者相比，能较理想地维持上颌窦内x线骨增强体积；早期种植体丢失未见显著差异。临床试验注册：（ChiCTR2200062886）
