The Twin
Block appliance
The Twin Block appliance is used to correct bite issues and improve jaw alignment and is commonly used to treat overbites and underbites. This appliance is made up of both an upper and lower component that work together to reposition the lower jaw.
These two appliances interlock at an angle, and they move your lower jaw forward and lock it into the ideal position when you bite together. Over time this forced position will train correct oral posture and become an effortless and permanent position for the jaw.
This appliance is designed to be worn full time, for a duration of about 9-12 months. This appliance can be used for adults and children, however, it is generally recommended for younger patients as their jaws are still growing and much easier to guide to the correct position.
The
Herbst appliance
The Herbst Appliance corrects jaw and tooth imbalances such as overbites by holding the lower jaw in a protrusive position. It is similar to the Twin Block Appliance except that it is not removable, thus not relying on the compliance of the patient for a successful outcome.
What should my child expect with the Herbst appliance?
When first administered, the appliance may feel a bit awkward and there may be some temporary discomfort, chewing difficulties, and speech changes. However, normal function and feeling should return with a week of the appliance being fitted.
Taking care of your child’s appliance and oral health
Since the appliance is fixed to the teeth, it is particularly important to maintain good oral health during treatment. Patients must brush and floss regularly and pay particular attention to the region of the appliance that sits adjacent to the gums, as this area is the most often neglected.
Make sure your child avoids chewing gum or any sticky foods such as caramel, as these can become stuck in the appliance and be very difficult to remove.
