We describe the preoperative application of limited cone beam computerized tomography (CT) using a Dental three-dimensional (3D)-CT as an assessment tool before minor oral surgery. The Dental 3D-CT provided 42.7 mm-high and 30 mm-wide rectangular solid images. This size covered the height of the mandible with standing teeth. Dental 3D-CT clearly demonstrated lesions in the maxillary and mandibular bone. Resorption of the bone due to disease expansion was depicted more clearly on the Dental 3D-CT than on conventional radiographs. Information about lesion location and the relationship between the lesions and their adjacent anatomical structures, such as the mandibular canal and maxillary antrum, was useful for minor oral surgery. Due to its high resolution and low radiation dose, Dental 3D-CT was useful for preoperative examination prior to minor oral surgery.
我们描述了在小型口腔手术前，使用牙科三维（3D）计算机断层扫描（CT）作为评估工具进行有限锥形束计算机断层扫描（CT）的术前应用。牙科3D-CT提供了42.7毫米高、30毫米宽的矩形立体图像。这个尺寸覆盖了有恒牙的下颌骨高度。牙科3D-CT清晰地显示了上颌骨和下颌骨的病变。与传统X线片相比，牙科3D-CT更清楚地描绘了由于疾病扩展导致的骨质吸收。关于病变位置以及病变与其相邻解剖结构（如下颌管和上颌窦）之间关系的信息，对小型口腔手术很有用。由于其高分辨率和低辐射剂量，牙科3D-CT对小型口腔手术前的术前检查很有用。
