In clinical work, many patients are more concerned about the impact of aligners on the appearance, often ask me a lot of questions on this issue, now sorted out: child patients: as children patients less social activities, in addition to individual special circumstances of children, I recommend that they use metal brackets, metal brackets and the friction between the arch wire is relatively small, the doctor to the patient after the force, can be very good to achieve the pre With the development of orthodontic technology, there are many new metal brackets, such as self-locking brackets, etc., which facilitate the treatment of patients and shorten the treatment time, and it is relatively easy to clean and not easy to color, so it is a better choice for many children patients. Adult patients: Many adults ask me what is the point of ceramic brackets, and I tell them that the only point is that it is more beautiful, other than that there is no advantage, the friction between it and the arch wire is relatively large, and the doctor can not achieve the effect well after adding force, and there is a certain impact on the course of treatment, and it is easy to color, especially after eating curry, it is thicker than the metal brackets, and it will be a little uncomfortable. It is also worth noting that it is much harder than the teeth themselves, which can easily cause abnormal tooth wear, and it is also very troublesome to remove, as it is very tightly bonded to the teeth, often forming a chemical bond, which takes a lot of trouble to remove. Of course, if the patient’s financial situation allows, adult patients can also choose lingual brackets to completely hide the aligners and achieve true aesthetics.
