Abstract：
UNASSIGNED: 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).
UNASSIGNED: 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.
UNASSIGNED: 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 (P < 0.001). Multivariable analysis indicated that factors significantly associated with the AV in both groups included AA and VH (P < 0.01).
UNASSIGNED: Clinicians can predict the bone volume for sinus augmentation by measuring the augmentation height and angle.

摘要：
■关于上颌窦增强术中植骨的确切数量尚未达成共识。这项研究的目的是估计增加鼻窦的最小骨体积，并研究影响增加体积（AV）的因素。
■这项研究包括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，在3、5、7和9mm的垂直高度（VH）几乎进行了圆顶形窦增强。测量增大角（AA）和窦宽度（SW）。使用三维图像处理程序3DSlicer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)。A组,在3、5、7和9mm的VHs下，平均AVs分别为0.062、0.271、0.642和1.287cc，分别,B组,平均AVs分别为0.037,0.230,0.594和1.230cc.单变量分析显示两组与房室病变显著相关的因素包括SW,AA,和VH(P<0.001)。多因素分析显示，与AV相关的因素包括AA和VH（P<0.01）。
■临床医生可以通过测量增加高度和角度来预测用于鼻窦增加的骨体积。
