ORTHODONTIC DISORDERS & TREATMENT

Crossbite

Crossbite can occur in the front and/or the sides of the mouth: One or more upper teeth bite on the inside of the lower teeth. This can occur with a single tooth or multiple teeth. Early correction of crossbite is recommended.

How can a crossbite be orthodontically corrected?

If there is a single tooth crossbite, the tooth can be moved with braces into the correct position. In some cases, a retainer can be utilized. With multiple teeth in crossbite, the arch needs to be expanded with braces or other intra-oral appliances.

This problem should be corrected because it can:

Cause premature wear of the teeth
Cause gum disease including bone loss
Cause asymmetrical development of the jaws
Cause dysfunctional chewing patterns
Make your smile less attractive

Openbite

Openbite is an insufficient vertical overlap of the teeth. It is caused by oral habits such as tongue thrust, digit sucking or when the jaws don’t grow evenly. Timing of treatment is critical to the overall success of the therapy.

How can an openbite be orthodontically corrected?

Openbite can be corrected through growth modification of the jaws using braces, extrusion of the anterior teeth and in some cases surgical correction of the jaws. Also breaking oral habits, such as digit sucking, will facilitate the correction of an openbite.

Overbite – Class II

Overbite occurs when the upper front teeth protrude over the lower front teeth. Generally there is no contact between the upper and lower front teeth. Often you cannot see the lower incisors. Overbite is due to a disproportionate amount of eruption of front teeth or over development of the bone that supports the teeth and a front to back discrepancy in the growth of the upper or lower jaw (Class II Relationship). Overbite is also known as a deep bite.

How can an overbite be orthodontically corrected?

Overbite can be corrected through moving the front teeth up and/or bringing the back teeth together, which will “open” the bite so the teeth are properly aligned and the deep bite is eliminated.

This problem should be corrected because it can:

Cause improper functioning of your front teeth
Result in the lower front teeth biting into the gum tissue of the upper palate leading to tissue problems
Unusual wear of the lower front teeth
Cause jaw or joint problems
Make your smile less attractive

Overjet — Class II

Overjet is also known as protrusion. In this case, the lower teeth are too far behind the upper front teeth. This can be caused by an improper alignment of the molars (Class II Relationship), a skeletal imbalance of the upper and lower jaw; flared upper incisors, missing lower teeth or a combination of all the above. In addition, oral habits such as thumb sucking, finger sucking or tongue thrusting can exacerbate the condition.

How can missing teeth be orthodontically corrected?

Overjet can be corrected through growth modification using a functional appliance and/or elastics to reduce the skeletal imbalance or extraction of teeth.

This problem should be corrected because it can:

prevent proper functioning of the front teeth
lead to premature wear
make your smile less attractive

Underbite — Class III

The lower teeth protrude past the front teeth. An underbite is usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or a combination of the two (Class III Relationship). Underbite can also be caused by flared upper incisors, missing lower teeth or a combination of all the above. Early correction of underbite is recommended.

How can an underbite be orthodontically corrected?

Underbite can be corrected through growth modification of the jaws, extraction of teeth and in some cases, surgical correction of the jaws.

This problem should be corrected because it can:

Prevent proper functioning of the front teeth or molars which can lead to premature wear of the teeth
Cause chewing or eating problems
Cause jaw or joint problems
Make your smile less attractive
