Digital Orthodontic Systems

The most popular 3D techniques in orthodontics are CBCT (cone beam computerized tomography), the digitization of 3D facial, intraoral and model scans, and 3D printing devices with CAD/CAM (computer-aided design and manufacturing) technology. Three-dimensional cephalometry, which is done using a CBCT exam, allows for a more detailed evaluation of the craniofacial structure. With this method, the clinician can more easily detect and quantify craniofacial asymmetries, longitudinal growth, and subtle occlusal changes. CBCT has been shown to be extremely important in the treatment of patients with impacted teeth. Other uses of CBCT in the Orthodontic field are the accurate placement of mini-implants, the detection of anomalies in the mandibular condyle and temporomandibular joint. Also, three-dimensional measurements of the airway can be accurately obtained with the use of a CBCT. Scanners in orthodontics have played an important role in digital diagnosis, treatment planning, and research. Significant benefits from intraoral scanners include more comfort, lower risk of allergic reactions, the streamlining of clinical procedures, easy storage, and the ability to record and share data between peers. One of the most cutting-edge technologies in the manufacturing field is three-dimensional printing. Producing dental casts was one of the very first applications for three-dimensional printers in orthodontics. The various 3D printing technologies can have an impact on the accuracy of three-dimensional printed models. The PPP printing technology is the most accurate of them, and it is followed by the DLP, SLA, LCD, and FFF printing technologies in that order, according to the present literature. The design of the base appears to have an impact on the accuracy of 3D dental models as well. It has been established that the standard dental model base and a horseshoe model with a posterior connection are realistic, although the horseshoe design is susceptible to distortion. The printing materials used also have an impact on the precision of the 3D-printed dental models. It is important to mention that none of these variables have an impact on the clinical orthodontic result. Since none of the aforementioned criteria have a clinically significant impact on the clinical outcome, doctors can choose a printer based on how expensive and time-consuming it is to create dental models for orthodontic applications.
