A functional appliance, such as a Twin Block, is a removable brace that works on both the upper and lower jaws at the same time. They are widely used in the treatment of prominent upper teeth (Class II) and small lower jaws. They are often recommended as a form of early intervention before having fixed braces.
Generally this stage of treatment will take between 6-12 months, and the orthodontist here at Glow Dental will advise you how long you will need to wear.
Regular visits will be needed to make continued adjustments to the brace. For this type of treatment to be successful, it is important to have the cooperation of your child. Failure to regularly wear the appliance, or continued breakages will prolong the length of treatment.
