The most common reason why the upper and lower teeth might not meet is a misaligned jaw. Overbites and underbites are the two leading types of jaw misalignment. The effects of this issue are emotional and physical.

Misalignment will affect your clients’ breathing, eating, and speech and cause some level of jaw discomfort even when he/she is not moving the jaw. The condition also makes a patient self-conscious since his/her facial features will not be as well-aligned as they should.

Clear dental aligners and braces have for a long time been your only solution for the correction of misaligned jaws. Functional appliances are, however now recommended for the correction of severe jaw misalignment. These are meant to use the natural forces of a patient’s jawbone to align a patient’s jaw.

The use of these appliances is the primary feature of interceptive orthodontics. Here are some of the functional appliances you can use to correct jaw misalignment.


Retainers in different colorsThis is a removable appliance that corrects overbites through the promotion of lower jaw growth. It is often the choice appliance when a client has an overjet. The bionator will be held to the upper teeth using an acrylic archwire.

Its upper portion will rest behind the front teeth while the lower one is in contact with the bottom teeth. To maximize its efficacy, your patient should wear the bionator throughout except when brushing or eating.

Twin Block Appliance

This resembles the bionator but features two pieces rather than one. As such, it is more comfortable and less bulky for your clients and has higher compliance rates. Flexible wires will hold the top half of a twin block appliance to the upper teeth while the other half contains the lower teeth.

The appliance is removable but should be worn throughout. Moreover, it is versatile, and you can include expansion devices, springs, and clasps to customize it to a client’s needs.

The Herbst Appliance

This is fixed to the top of your molars. It has a rod and small tube that extends to the bottom of the teeth and puts pressure on a patient’s lower jaw. The use of a Herbst appliance generally produces results within a year. Since this is a fixed device, the compliance of your clients is not an issue.

The Biteplane

This suffices for the correction of a deep overbite where the upper ones excessively overlap the lower front teeth. A biteplane works by averting the biting down of a patient on his/her back teeth.

To this end, the back teeth will emerge gradually and reduce the front teeth’s overlap. The biteplane should be worn throughout other than when brushing or eating and brushed at least daily.

The above functional appliances are more comfortable compared with other options since they support the normal process of jaw growth. Their use might cause some discomfort initially though this will resolve within a few days as the patient becomes accustomed to them.

To guarantee they work for your clients, get the appliances fabricated by the best orthodontics laboratory available. This might attract a higher cost compared to some labs, but the resultant appliance will be comfortable and effective for your clients.
