Invisible orthodontics has the following advantages: 1, beautiful and comfortable: aligners without wire brackets, transparent and thin, almost imperceptible to onlookers; 2, accurate positioning: through the computer three-dimensional image technology to simulate the process of tooth movement, and according to this made orthodontic appliances, wear the teeth will accurately move in the designed direction; 3, convenient and fast: aligners are not fixed on the teeth, the customer can take off and wear, will not have a negative impact on your This will not have a negative impact on your working life. However, it must be noted that the current technical limitations, the trial range is narrow, suitable for the crowd: individual teeth misalignment; gaps, uneven teeth; people who wish to personalize the design is more suitable for the use of bracketless invisible orthodontics. Principle: Invisible bracketless orthodontics is the use of bracketless invisible orthodontic appliances installed in the corresponding parts, the need for orthodontic parts to apply the appropriate pressure, so that the deformed parts in the long time under pressure slowly move to the correct position. The orthodontic appliances are installed in different ways depending on the area to be orthodontically corrected and the post-orthodontic state. Invisible orthodontic procedure without brackets: First of all, the doctor should do a comprehensive examination for the orthodontist, take models, X-rays and photos for the orthodontist. After all these diagnoses are made, the doctor will then make a design for the recipient. The design may involve whether the orthodontist should extract teeth or not, and severe jaw deformities may require appropriate surgery to achieve good results. Then, an orthodontic plan is made based on the customer’s underlying conditions. The process of tooth movement is simulated by computer and accordingly, personalized braces made of polymer material are designed and handed over to the factory to be made into finished braces, a process that takes about one to two weeks. Once done, the customer is notified to wear the braces at the hospital. Throughout the treatment process, the doctor will request regular check-ups at the hospital according to the patient’s condition to understand the effect of the treatment. And appropriate adjustments will be made according to the situation.
