Orthodontics is the treatment of the irregularities of teeth (especially alignment and “bite”) including the use of braces and other fixed and removable appliances and controlling various aspects of facial growth (dentofacial orthopaedics) and to influence the shape and development of the jaw.
There are many types of braces ranging from simple wires only inside the teeth to fixed brackets inside and outside the teeth, clear plastic aligners and removable plastic appliances.
