AIM To evaluate the radiographic outcomes of lateral sinus floor elevation with simultaneous implant placement at sites without sinus membrane perforation (SMP) and sites with SMP managed with a resorbable membrane. MATERIALS AND METHODS One hundred and thirty-nine patients and 170 implants (56 perforation, 114 non-perforation) were included. Cone-beam computed tomography (CBCT) images were taken before surgery (T0), immediately after surgery (T1) and 6 months after surgery (T2). Post-operative augmentation parameters, including endo-sinus bone gain (ESBG) along the implant axis, mean new bone height (NBH) surrounding the implant and augmentation volume (AV), were measured at T1 and T2. RESULTS At T1, there were no significant differences in ESBG, NBH and AV between the two groups. At T2, although ESBG did not significantly differ between the two groups, NBH (8.50 ± 1.99 mm vs. 9.99 ± 2.52 mm, p = .039) and AV (519.37 ± 258.38 mm3 vs. 700.99 ± 346.53 mm3, p < .001) were significantly lower in the perforation group. The shrinkage of graft material from T1 to T2, including ΔESBG (p = .002), ΔNBH (p < .001) and ΔAV (p < .001), was higher in the perforation group. CONCLUSIONS SMP during LSFE with simultaneous implant placement is associated with greater resorption of the grafted area at a 6-month follow-up.

无穿孔部位和有可吸收膜治疗的穿孔部位窦底外侧抬高的影像学结果:一项回顾性研究。



目的 评估在没有窦房膜穿孔 (SMP) 的部位和有可吸收膜管理的 SMP 部位同时放置植入物的同时升高窦底的影像学结果。材料和方法 纳入 139 例患者和 170 例植入物 (56 例穿孔,114 例非穿孔)。手术前 (T0) 、手术后即刻 (T1) 和手术后 6 个月 (T2) 拍摄锥形束计算机断层扫描 (CBCT) 图像。在 T1 和 T2 测量术后增强参数,包括沿种植体轴线的鼻窦内骨增益 (ESBG)、种植体周围的平均新骨高度 (NBH) 和增强体积 (AV)。结果 T1 时,两组 ESBG 、 NBH 和 AV 差异无统计学意义。在 T2 时,虽然两组之间 ESBG 没有显著差异,但穿孔组的 NBH (8.50 ± 1.99 mm vs. 9.99 ± 2.52 mm,p = .039) 和 AV (519.37 ± 258.38 mm3 vs. 700.99 ± 346.53 mm3,p < .001) 显著降低。穿孔组从 T1 到 T2 的接枝材料收缩率较高,包括 ΔESBG (p = .002)、ΔNBH (p < .001) 和 ΔAV (p < .001)。结论 在 6 个月的随访中,LSFE 期间的 SMP 同时植入种植体与移植物区域的更大吸收相关。
