BACKGROUND/PURPOSE: Various studies have shown that use of absorbable collagen sponge (ACS) in maxillary sinus augmentation promotes new bone formation. This study aimed to assess changes in bone height of the maxillary sinus floor and to identify factors associated with these changes when performing sinus augmentation using ACS.
This retrospective study included patients who underwent simultaneous implant placement and maxillary sinus augmentation using ACS through a crestal (CA) or lateral (LA) approach. Changes in bone height at 12 months (G2, primary outcomes) were evaluated by cone-beam computed tomography. Factors associated with these changes were evaluated, including age, sex, smoking, location, span, number of ACSs, sinus perforation, sinus membrane elevation height, and residual bone height. Variables significantly associated with G2 were evaluated by multivariable analyses based on the generalized estimating equation.
Overall, 108 patients were evaluated, including at 182 implant sites (CA, 53; LA, 129). G2 was 2.16 ± 1.51 mm (residual bone height, 8.11 ± 1.58 mm) and 4.62 ± 2.04 mm (residual bone height, 5.54 ± 2.52 mm) in the CA and LA, respectively ( < 0.001). Factors significantly associated with G2 included sex ( < 0.001), perforation ( < 0.001), and residual bone height ( < 0.001) in the CA, and sinus membrane elevation height ( = 0.013) and residual bone height ( < 0.001) in the LA.
Clinicians need to make efforts to sufficiently elevate the sinus membrane and minimize perforations in order to achieve desired levels of new bone formation.
背景/目的：多项研究表明，在上颌窦提升术中使用可吸收胶原海绵（ACS）可促进新骨形成。本研究旨在评估上颌窦底骨高度的变化，并确定在使用ACS进行窦提升时与这些变化相关的因素。
这项回顾性研究纳入了通过牙槽嵴顶（CA）或外侧（LA）入路同时进行种植体植入和使用ACS进行上颌窦提升的患者。通过锥形束计算机断层扫描评估12个月时的骨高度变化（G2，主要结局）。评估与这些变化相关的因素，包括年龄、性别、吸烟情况、位置、跨度、ACS数量、窦穿孔、窦膜提升高度和剩余骨高度。基于广义估计方程，通过多变量分析评估与G2显著相关的变量。
总体上，评估了108例患者，共182个种植位点（CA组53个，LA组129个）。CA组G2为2.16±1.51mm（剩余骨高度8.11±1.58mm），LA组为4.62±2.04mm（剩余骨高度5.54±2.52mm）（P<0.001）。与CA组G2显著相关的因素包括性别（P<0.001）、穿孔（P<0.001）和剩余骨高度（P<0.001），与LA组G2显著相关的因素包括窦膜提升高度（P = 0.013）和剩余骨高度（P<0.001）。
临床医生需要努力充分提升窦膜并尽量减少穿孔，以实现理想的新骨形成水平。
