Abstract:
Through the analysis on principles of dental panoramic radiography, we analyzed the influence factors of the dental arch, and provided the main principles for optimizing design to improve the image quality. Through the analysis on the human dental arch’s form, we optimized the radiographic procedure. Many factors affect the quality panoramic image, but the focal trough’s design is one of the most important factors, especially for canine regions. Optimizing design of focal trough can lessen degrees of horizontal and vertical magnification, also can reduce geometric distortion and overlapped images of teeth.
