: To evaluate changes in bone volume induced by absorbable collagen sponge (ACS) use during maxillary sinus floor elevation and to identify associated factors.
After elevating the sinus membrane through a crestal approach (CA) or lateral approach (LA), ACS (AteloPlug; Bioland) was inserted, and dental implants were placed simultaneously. Changes in bone volume at 12 months were evaluated by three-dimensional (3D) analyses of cone-beam computed tomography images. Factors including age, sex, smoking status, span, number of ACSs, and perforation were assessed for associations with changes in sinus bone volume using uni- and multivariable analyses based on the generalized estimating equation.
: Medical records of 108 patients were collected and retrospectively evaluated, with 135 regions of interest defined (CA, 45; LA, 90). The changes in bone volume at the sinus floor were 159.38±134.52 mm and 486.83±253.14 mm in the CA and LA groups, respectively. Bone volume changes in the CA group were significantly affected by the number of ACSs (<0.001) and perforation of the sinus membrane (<0.001), whereas bone volume changes in the LA group were significantly affected by the number of ACSs (=0.001).
: Use of ACS for maxillary sinus elevation resulted in detection of new bone formation in 3D analysis. Clinicians can ensure stable amounts of bone formation by inserting an adequate number of ACSs.
评估在上颌窦底提升术中使用可吸收胶原海绵（ACS）引起的骨体积变化，并确定相关因素。
通过牙槽嵴顶入路（CA）或外侧入路（LA）提升窦膜后，插入ACS（AteloPlug；Bioland），并同时植入牙种植体。通过锥形束计算机断层扫描图像的三维（3D）分析评估12个月时的骨体积变化。使用基于广义估计方程的单变量和多变量分析评估年龄、性别、吸烟状况、跨度、ACS数量和穿孔等因素与窦骨体积变化的相关性。
收集并回顾性评估了108例患者的病历，定义了135个感兴趣区域（CA组45个；LA组90个）。CA组和LA组窦底的骨体积变化分别为159.38±134.52mm和486.83±253.14mm。CA组的骨体积变化受ACS数量（<0.001）和窦膜穿孔（<0.001）的显著影响，而LA组的骨体积变化受ACS数量（=0.001）的显著影响。
在3D分析中，使用ACS进行上颌窦提升可检测到新骨形成。临床医生可以通过插入足够数量的ACS来确保稳定的骨形成量。
