Underbite Surgery Correction

 An underbite occurs when the lower jaw exceeds the upper jaw, causing the bite to be off and incorrect relation between the two jaws.

Most people have some form of bite issue, but most are able to function normally and eat and talk properly.  For some that have severe jaw issues, orthodontic treatment or surgery may be required.

Often times Orthodontist will recommend surgery with braces treatment before and after the jaw surgery.  Each case is different and will very from person to person.

Malocclusions may be coupled with skeletal disharmony of the face, where the relations between the upper and lower jaws are not appropriate. In these cases the dental problem is, most of the time, derived by the skeletal disarmony.

Malocclusions can be divided into three types, depending on the sagittal relations of teeth and jaws:

Class I: The patient's bite is normal but their teeth are mispositioned or crowded.

Class II: (retrognathism or Excessive overjet) is when the upper front teeth are 3mm or more prominent than the lower front teeth. In this case the patient has very often a short mandible.

Class III: (prognathism or negative overjet) is when the lower front teeth are more prominent than the upper front teeth. In this case the patient has very often a large mandible or a short maxillary bone.

In many cases jaw surgery can be covered by medical insurance companies if deemed not to be cosmetic.  You would have to have problems eating, talking, etc to be considered not cosmetic.

In some cases, orthodontic braces can move the teeth with the use of rubber bands and adjust the bite to become more comfortable for the user.
