1, beautiful and comfortable: braces 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 braces, wear the teeth will accurately move in the designed direction; 3, convenient and fast: braces are not fixed on the teeth, the customer can take off and wear, will not have a negative impact on your work 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 these diagnoses are made, the doctor will then make a design for the recipient. The design may involve whether the orthodontic patient should have teeth extracted or not, and severe jaw deformities may require appropriate surgery to achieve good results. The doctor then develops an orthodontic plan based on the customer’s underlying conditions, and a computer simulates the tooth movement process. Based on this, a personalized polymer aligner is designed and sent to the factory to be made into a finished aligner, a process that takes about one to two weeks, and once it is done, the customer is notified to wear the aligner 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 adjust appropriately according to the situation. Specific steps: 1.Take mold and X-ray 2.Obtain customer facial aesthetic information 3.Develop treatment plan 4.3D simulation of the treatment process 5.Make bracketless braces 6.Wear treatment
