The difference between ceramic braces and steel braces can be divided into the following points: First, ceramic braces belong to all-ceramic teeth, which are more permeable, no metal, and will not have any interference when doing MRI and enhanced PETCT. Steel braces will have interference with the development, so doctors recommend doing ceramic braces more often. Second, if the patient has a tight bite and a short bite distance, it is recommended to do steel braces because steel braces can be made very thin and ceramic braces must require a certain thickness. Patients bite force is larger, steel braces are preferred, can wear and can adapt to a lower bite relationship. Third, the hardness of ceramic braces is close to the real teeth, steel braces will produce a certain abrasion phenomenon on the jaw teeth because they are too hard, so according to the patient’s different needs, choose while different crowns, but also according to the doctor’s advice to choose, which are beneficial.
