There is no such thing as a universal appliance system suitable for all dysgnathia and for every patient. It is therefore necessary to compare the application of the individual systems. In principle, orthodontal appliances can work either functionally or through external forces.

Functionally working appliances work with the body's own forces or through the change in the chewing and facial muscles' functional balance. External mechanical elements are applied in appliances, whose effect rests on external forces (e.g., screws, springs, wire arches). A combination of both appliance systems is possible. Depending on the appliance's attachment type to the teeth, we differentiate between removable and fixed systems. The removable systems include plates and functional orthodontal devices, the fixed systems include multiband appliances and extraoral devices.
