Functional Appliances
Functional appliances are devices used to correct a significant disharmony in the relationship between the upper and lower jaws. They work by influencing the growth and development of a growing patient.
The most common use of a functional appliance is to encourage the forward growth of a retrusive or “under-developed” lower jaw. The functional appliance holds the lower jaw forward over a period until the teeth, jaws and joints have “adapted” and the desired jaw position has been obtained.
The effectiveness of a functional appliance depends on:
how much the appliance is worn
how quickly the patient is growing
how quickly the patient is growing
Functional appliances align the jaws not the teeth, so they are usually used as a first stage of treatment (in a growing patient with a significant jaw disharmony) prior to the alignment of the teeth with fixed appliances (braces).
The most common types of functional appliance are listed below:
