BACKGROUND/PURPOSE: No consensus has been established regarding the exact amount of bone grafting in maxillary sinus augmentation. The aim of this study was to estimate the minimum bone volume for sinus augmentation and to investigate the factors that influence the augmentation volume (AV).
This study included patients with cone-beam computed tomography scanning. Dome-shaped sinus augmentation was performed virtually at vertical heights (VH) of 3, 5, 7, and 9 mm in Group A (without implantation) and Group B (with implantation). The augmentation angle (AA) and the sinus width (SW) were measured. The AV was measured using the three-dimensional image processing program 3D Slicer. Univariable and multivariable analyses were conducted.
This study included 30 patients (120 subjects). In Group A, the mean AVs were 0.062, 0.271, 0.642, and 1.287 cc at VHs of 3, 5, 7, and 9 mm, respectively, in Group B, the mean AVs were 0.037, 0.230, 0.594, and 1.230 cc. Univariable analysis indicated that factors significantly associated with the AV in both groups included SW, AA, and VH ( < 0.001). Multivariable analysis indicated that factors significantly associated with the AV in both groups included AA and VH ( < 0.01).
Clinicians can predict the bone volume for sinus augmentation by measuring the augmentation height and angle.
背景/目的：在上颌窦提升术中，关于确切的骨移植量尚未达成共识。本研究的目的是估计窦提升所需的最小骨量，并研究影响提升量（AV）的因素。
本研究纳入了接受锥形束计算机断层扫描的患者。在A组（未植入）和B组（植入）中，分别在3、5、7和9毫米的垂直高度（VH）虚拟进行穹顶形窦提升。测量提升角度（AA）和窦宽度（SW）。使用三维图像处理程序3D Slicer测量AV。进行单变量和多变量分析。
本研究包括30名患者（120名受试者）。在A组中，3、5、7和9毫米VH处的平均AV分别为0.062、0.271、0.642和1.287立方厘米；在B组中，平均AV分别为0.037、0.230、0.594和1.230立方厘米。单变量分析表明，两组中与AV显著相关的因素包括SW、AA和VH（<0.001）。多变量分析表明，两组中与AV显著相关的因素包括AA和VH（<0.01）。
临床医生可以通过测量提升高度和角度来预测窦提升的骨量。
