Classifying and Diagnosing 199 Impacted Permanent Using Cone Beam Computed Tomography

摘要

Grasping the position of embedded teeth in jaw bone and their spatial relationship with neighboring anatomical structures accurately is the foundation of orthodontic and maxillofacial surgical treatments. Cone beam computed tomography (CBCT), a newly developed imaging technique, which produces high definition and high resolution three-dimensional volumetric images, can provide accurate dynamic 3D images and six-surfaces visual angle for locating embedded teeth to get intuitive fault images in comparison with conventional CT. CBCT is being used in the practice of oral and maxillofacial radiology with increasing frequency to make up the shortcomings of traditional plane images. The purpose of this prospective study was to use CBCT to locate 199 impacted teeth of 103 patients, and make a classification.
