The study presents quantitative computed tomography (QCT) as a noninvasive method for analyzing the inner bone structure. Randomly selected mandibles from the osteological collection of the "Drago Perović" Institute of Anatomy, School of Medicine, Zagreb were CT-scanned in five bone areas. Analyzing the densitometry curve in two horizontal levels the relation between the compact and spongy bone and the total amount of bone substance in each area were determined. The smallest bone quantity was found in the area of the neck and angle of the mandible, the areas of most frequent bone fractures. The alveolar part of the bone, apart from the area of the angle, was considerably less thick than the base of the mandible. The compact bone was predominant in all CT-scans.
该研究提出定量计算机断层扫描（QCT）作为一种用于分析骨内部结构的非侵入性方法。从萨格勒布医学院“德拉戈·佩罗维奇”解剖学研究所的骨学收藏中随机选取下颌骨，在五个骨区域进行CT扫描。通过分析两个水平层面的骨密度曲线，确定了每个区域中密质骨与松质骨之间的关系以及骨物质的总量。在最常发生骨折的下颌骨颈部和角部区域发现骨量最少。除角部区域外，牙槽骨部分比下颌骨基部薄得多。在所有CT扫描中，密质骨占主导地位。
