We propose and validate a computer-aided system to measure three different mandibular indexes: cortical width, panoramic mandibular index and, mandibular alveolar bone resorption index.
Repeatability and reproducibility of the measurements are analyzed and compared to the manual estimation of the same indexes.
The proposed computerized system exhibits superior repeatability and reproducibility rates compared to standard manual methods. Moreover, the time required to perform the measurements using the proposed method is negligible compared to perform the measurements manually.
We have proposed a very user friendly computerized method to measure three different morphometric mandibular indexes. From the results we can conclude that the system provides a practical manner to perform these measurements. It does not require an expert examiner and does not take more than 16 seconds per analysis. Thus, it may be suitable to diagnose osteoporosis using dental panoramic radiographs.
我们提出并验证了一个计算机辅助系统，用于测量三个不同的下颌指数：皮质骨宽度、全景下颌指数和下颌牙槽骨吸收指数。
分析并比较了测量的可重复性和再现性与相同指数的手动估计值。
与标准手动方法相比，所提出的计算机化系统具有更高的可重复性和再现性率。此外，与手动测量相比，使用所提议的方法进行测量所需的时间可以忽略不计。
我们提出了一种非常用户友好的计算机化方法来测量三种不同的下颌形态指数。从结果可以得出结论，该系统提供了一种实用的方法来进行这些测量。它不需要专家检查，每个分析不超过 16 秒。因此，它可能适用于使用牙科全景 X 光片诊断骨质疏松症。
