Computed tomography (CT) and X-ray images have been extensively used as a valuable diagnostic tool in dentistry for surgical planning and treatment. Nowadays, dental cone beam CT has been extensively used in dental clinics. Therefore, it is possible to employ three-dimensional (3D) data from the CT to reconstruct a two-dimensional (2D) panoramic dental image that provides a longitudinal view of the mandibular region of the patient, avoiding an additional exposure to X-ray. In this work, we developed a new automatic method for reconstructing 2D panoramic images of the dental arch based on 3D CT images, using Bézier curves and optimization techniques. The proposed method was applied to five patients, some of them with missing teeth, and smooth panoramic images with good contrast were obtained.
计算机断层扫描（CT）和X射线图像已被广泛用作牙科手术规划和治疗中的重要诊断工具。如今，牙科锥形束CT已在牙科诊所广泛使用。因此，可以利用CT的三维（3D）数据重建二维（2D）全景牙科图像，该图像提供患者下颌区域的纵向视图，避免额外的X射线照射。在这项工作中，我们开发了一种基于3D CT图像重建牙弓二维全景图像的新自动方法，使用贝塞尔曲线和优化技术。该方法应用于五名患者，其中一些患者有牙齿缺失，获得了对比度良好的平滑全景图像。
