Orthopaedic appliances

Orthopaedic appliances are used in growing patients to correct dental and skeletal irregularities, particularly those affecting the alignment of the teeth and jaws. This form of treatment can prevent the need for more complex orthodontics or surgery later on in life.

At The Bachmayer Orthodontic Clinic we provide the following orthopaedic appliances:

Orthopaedic appliances

Expansion plate

An expansion plate works by gradually expanding space in the upper jaw and is used to correct bite discrepancies and create space for more teeth. It is important to note that while expansion plates are removable, they must be kept in place during treatment to maintain their effectiveness.

What does an expansion plate achieve?

An expansion plate serves to widen the upper jaw, creating a broader and more attractive smile. It is also effective in correcting bite alignment which, left untreated, could lead to problems with the jaw joints and teeth later in life. Expansion is most effective while the jaws are still developing.

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.

Headgear

Headgear is an appliance typically used in growing patients to correct overbites by holding back the growth of the upper jaw, allowing the lower jaw to catch up. Headgear can also be used to make more space for teeth to come in.

Headgear needs to be worn approximately 12 to 22 hours a day to be truly effective in correcting the overbite. The treatment lasts usually anywhere from 6 to 18 months, depending on the severity of the overbite and how much a patient is growing.

Reverse Headgear is an appliance used in young growing individuals who have under-developed upper jaws. It acts by putting forward traction on the upper jaw so that it may “catch up” in growth to the lower jaw.
