Invisible orthodontics is a new orthodontic technique that uses a series of transparent movable aligners to achieve orthodontic treatment of malocclusions. It uses aligners made of polymer materials without the brackets and wires found in traditional fixed aligners, which allows patients to straighten their teeth without compromising aesthetics. Compared to traditional braces, invisible aligners are aesthetically pleasing, comfortable and convenient. Invisalign is an emerging orthodontic technology that relies heavily on computers to aid in diagnosis and make designs. Prior to invisible orthodontics, facial and occlusal photographs are also taken, and an oral cavity model is taken. Diagnostic imaging includes curved tomograms. Lateral cephalograms and CTs are taken. This data is then uploaded to a computer system, which analyzes the data, makes the diagnosis and designs the aligner. The patient can see the exact changes in the orthodontic process and the results after the orthodontic treatment according to the computer simulation. Once the patient sees the results, he or she can submit them for production if he or she is satisfied. Based on the computer analysis and data, the appropriate aligners are made. Generally dozens of pairs of clear movable aligners are made for orthodontics, and patients only need to wear the aligners on time as required, which often does not require too long of a follow-up visit compared to traditional orthodontic methods, which are generally done once a month or so. The invisible orthodontic method is very popular at this stage. It is popular because it can achieve both aesthetic comfort and other requirements during the patient’s orthodontic treatment. But not for particularly difficult malocclusions, such difficult cases, the traditional method works a little better.
