Computed Tomography is an imaging method called CT for short, it is used to prepare cross-sectional images, and the CT scanner consists of a fan-shaped x-ray tube and a set of detectors, which is the x-ray detector outside received from the patient.
3D printing is an evolving technology that will play an important role in the diagnosis and treatment of dentistry and orthodontics. It is known as the production of a 3D physical object (prototype) using CT and CBCT data and preparing virtual models with the help of computer technology.
In recent years, a special type of simple radiography has become popular, which is called digital radiography. The difference between this method and the traditional method is the image receiver used. This is the difference between new digital cameras and old cameras.
It is a hand-held device used to create and transmit digital images from the oral cavity to a screen. The light from the scanner is spread on the desired objects, such as the complete dental arch, and then a 3D model processed by the scanner software is displayed in real time on the monitor.
In this method, the face is imaged at different angles with the help of 3D scanners. Then a 3D file is created based on the changes after the nose operation or other parts of the face, and the patient can see his face after the operation before surgery.
