Protrusion orthodontics can be carried out, but the treatment of protrusion caused by different reasons is different, generally speaking, divided into the following two kinds, dental protrusion and bony dental protrusion. 1, if it is purely dental protrusion and the ratio of upper and lower jaw bone is basically normal, then protrusion orthodontics can be solved by orthodontics. If it is a bony protrusion, the problem cannot be completely solved by orthodontics alone. 2, the traditional orthodontics can only change the problem of tooth misalignment, if used for bony protrusion of teeth, there will be a rebound phenomenon. Therefore, for the more serious bony protrusion orthodontic treatment may require surgical treatment, the specific situation needs to be examined by a doctor to determine.
