Herbst

Herbst

We often use orthopedic appliances (devices that help growth) as opposed to orthodontic appliances (devices that move teeth) when a patient's lower jaw has not grown enough. Most of these appliances are semi-permanent, which means they are fixed on to the teeth. This includes the Herbst appliance.

Removable appliances are available as well and include the Twin Block, Monoblock and Bionator. Unfortunately, several studies have shown removable appliances to be less effective at helping the lower jaw grow. These appliances are large and cumbersome, they often are hard to speak and function with (yes, your child has to wear them to school), and they usually have a poor fit – it's no wonder kids don't wear them!

Studies have shown that the clinical effectiveness of semipermanent appliances is far superior than removable appliances – which is why, Dr. Virdee will always recommend the appliance that will give you the best results – a fixed Herbst appliance. There are many versions of the Herbst appliance, some that include an expander or a stabilizing bar across the upper jaw, or some that have a bar in front of the lower incisors. Regardless of the permutations of this appliance, they have one major function: to help with the growth of the lower jaw.

How long is the treatment with a Herbst appliance?

Treatment time with the Herbst appliance is usually 1 year, though this may vary depending on the child's unique needs. If your child has their adult teeth by the time the appliance is removed we will continue with braces, otherwise there will be a rest period between phase I treatment and phase II treatment. By taking advantage of growth when a patient is younger, it is possible to avoid complicated and invasive procedures like surgery or extraction of permanent teeth.

Adjusting to the Herbst appliance?

Like anything new, your child has to adjust to the Herbst appliance in their mouth. The good news is, because children are more resilient than adults, it's easier for them to adapt to something new. It usually takes about a week to get used to eating, chewing and speaking with the appliance. Eating softer foods will help with the muscle tenderness that may occur in the first week or two as your child gets used to their appliance. It is important to eliminate sticky foods, like candy and gum or hard, crunchy foods which can damage the appliance and lengthen treatment time.
