To investigate the potential influence of different grafting materials on maxillary sinus membrane dimensions and ostium patency following lateral sinus floor elevation (SFE) as assessed using cone-beam computed tomography (CBCT).
A total of 40 sinuses in 40 patients were included. Twenty sinuses were referred for SFE with deproteinized bovine bone mineral (DBBM), and the remaining 20 sinuses were grafted with calcium phosphate (CP). CBCT was performed prior to and 3 to 4 days after surgery. The dimensions of the Schneiderian membrane volume and ostium patency were evaluated, and potential relationships between volumetric changes and any associated factors were analyzed.
The median increase in membrane-whole cavity volume ratios was 43.97% in the DBBM group and 67.58% in the CP group, demonstrating no statistically significant difference (p = 0.17). The rates of increased obstruction after SFE were 11.1% for the DBBM group versus 44.4% for the CP group (p = 0.03). The graft volume was found to be positively correlated with the postoperative membrane-whole cavity volume ratio (r = 0.79; p < 0.01) and the membrane-whole cavity volume ratio increase (r = 0.71; p < 0.01).
The two grafting materials seem to have a similar effect on transient volumetric changes in the sinus mucosa. However, the choice of grafting material should still be made with caution since sinuses grafted using DBBM exhibited less swelling and less ostium obstruction.
通过锥形束 CT（CBCT）评估不同移植物材料对经外侧窦底提升（SFE）后上颌窦膜尺寸和口的通畅性的潜在影响。
共纳入 40 名患者的 40 个窦腔。20 个窦腔因去蛋白牛骨矿物质（DBBM）而接受 SFE，其余 20 个窦腔用磷酸钙（CP）进行移植。在手术前和手术后 3 至 4 天进行 CBCT。评估了 Schneiderian 膜体积和口通畅性的尺寸，并分析了体积变化与任何相关因素之间的潜在关系。
DBBM 组膜-全腔体积比的中位数增加了 43.97%，CP 组增加了 67.58%，差异无统计学意义（p=0.17）。DBBM 组 SFE 后增加阻塞的发生率为 11.1%，CP 组为 44.4%（p=0.03）。发现移植物体积与术后膜-全腔体积比（r=0.79；p<0.01）和膜-全腔体积比增加（r=0.71；p<0.01）呈正相关。
两种移植物材料似乎对上颌窦黏膜的瞬时体积变化有相似的影响。然而，由于使用 DBBM 进行移植的窦腔肿胀和口阻塞较少，因此仍应谨慎选择移植物材料。
