Functional appliances

A functional appliance is used to treat young children and teenagers with a large protrusion (sticking-out teeth). It is important to correct a large protrusion to minimise the risk of a traumatic injury to the upper front teeth.

It works by pushing on the teeth, with a gentle force that is created when placing it in the mouth and closing the teeth together.

A functional appliance is custom-made to fit over the teeth. It can be easily inserted and removed for cleaning and meals.


  • A simple and effective method to correct large protrusions.
  • No need for a headgear
  • Many cases can be treated without extractions
