There are invisible braces for orthodontics and it is usually a set sequence. Patients go to the dentistry department to take a digital model and send it to the mechanic’s office, which will make a set of clear braces based on the alignment of the teeth. Patients can replace them at home without having to go to the hospital every month for a follow-up appointment. Invisible braces are not only suitable for patients with high aesthetic requirements, but also for patients who are studying or going to college abroad, so that they can be replaced every month without any delay in treatment. And because there are no brackets or archwires, there is no scraping of the lips or loss of brackets that can affect the correction. And after correction, the bite is generally better, because the whole bite is predetermined according to the digital, so the effect is very good, but the price is more expensive.
