The authors report on a new image processing technique, for the imaging of both mandible and maxilla, which is very useful for oral specialists, especially in pre- and postoperative protocols for dental implants. After performing very thin axial scans (1-2 mm) with overlapping and without gantry tilt, of the mandible and/or maxilla, the data are reconstructed with a Elscint DentaCT software. With this program, multiple panoramic alveolar views can be obtained in a very short time (about 5 minutes), with a focal plane which can be easily modified by the operator; these planes are parallel to the curved axis of maxilla or mandible. Furthermore, the operator can get multiple images absolutely cross-sectional to the curved axis of alveolar regions (radial sections) and can image the number of cross-sectional planes and the distance between them. In all studied patients (41 over the last 6 months, 66 images overall), DentaCT yielded an excellent representation not only of all anatomical structures but also of every single implant; this allowed a complete preoperative planning based on morphovolumetric, densitometric and spatial data, together with the correct evaluation of implant positioning and of osteointegration success.
作者报告了一种用于下颌骨和上颌骨成像的新图像处理技术，这对口腔专科医生非常有用，尤其是在牙种植体的术前和术后方案中。在下颌骨和/或上颌骨进行非常薄的轴向扫描（1 - 2毫米），扫描时重叠且不进行机架倾斜，之后使用Elscint DentaCT软件重建数据。通过该程序，可以在很短的时间内（约5分钟）获得多个全景牙槽视图，其焦平面可由操作员轻松修改；这些平面与上颌骨或下颌骨的曲线轴平行。此外，操作员可以获得与牙槽区域曲线轴绝对垂直的多个图像（径向截面），并可以对截面平面的数量及其之间的距离进行成像。在所有研究患者中（过去6个月内41例，共66幅图像），DentaCT不仅能出色地呈现所有解剖结构，还能呈现每一颗种植体；这使得基于形态体积、密度和空间数据进行完整的术前规划成为可能，同时能正确评估种植体的定位和骨整合的成功情况。
