The aim of this study was to evaluate the interradicular septum bone morphometric characteristics using cone beam computed tomography (CBCT) images, as well as to establish quantitative shortcuts to allow clinicians to make a faster and more reliable plan for immediate implant placement in the maxillary molars area. This retrospective quantitative study was conducted on CBCT images obtained from 100 patients. The morphometric analysis of the maxillary molars region was based on the parameters obtained on the sagittal and axial slices. The analysis performed on sagittal slices showed that the first maxillary molars had a wider interradicular septum when compared to the second molars, but the septum height in the first molars was significantly below the height in the second maxillary molars. The axial CBCT slices analysis showed that both interradicular septum perimeter and surface area were significantly more pronounced in the first than in the second maxillary molars. The interradicular furcation angle significantly correlated with the surface area (positively) and septum height (negatively) for both molars. The results of this study may recommend CBCT image analysis as a useful tool in predefining the circumstances that can allow for substantially better planning of immediate implant placement procedures in the region of maxillary molars.
本研究的目的是使用锥形束计算机断层扫描（CBCT）图像评估根间间隔的骨形态计量学特征，并建立定量捷径，以便临床医生能够更快、更可靠地制定在上颌磨牙区域立即植入种植体的计划。这项回顾性定量研究是对从100名患者获得的CBCT图像进行的。上颌磨牙区域的形态计量学分析基于矢状面和轴位切片上获得的参数。在矢状面上进行的分析表明，与第二磨牙相比，上颌第一磨牙的根间间隔更宽，但第一磨牙的间隔高度明显低于上颌第二磨牙的高度。轴位CBCT切片分析表明，上颌第一磨牙的根间间隔周长和表面积均明显大于第二磨牙。两颗磨牙的根间分叉角度与表面积（正相关）和间隔高度（负相关）均显著相关。本研究结果可能表明，CBCT图像分析是一种有用的工具，可用于预先确定能够显著更好地规划上颌磨牙区域立即种植体植入手术的情况。
