and other routine activities. Orthognathic surgery corrects these problems and,
in conjunction with orthodontic treatment, will improve the overall appearance of the facial profile.
Maxillary Advancement with Mandible Setback
Maxillary advancement is a type of orthognathic surgery that may be necessary to improve the facial contour
and normalize dental occlusion when there is a relative deficiency of the midface region.
This is done by surgically moving the maxilla with sophisticated bone mobilization techniques
and fixing it securely into place.
For most patients, the use of screws and miniplates have replaced wiring of the bone
and teeth required to hold the jaw stable. Inlay bone grafts can be utilized for space maintenance and secured
with screw and plate fixation, while onlay bone grafting is used to augment the bony skeleton and
improve facial soft tissue contour.
Third molar teeth (commonly referred to as wisdom teeth) consist of the mandibular and maxillary third molars;
they usually appear between the ages of 17 and 25. They are called wisdom teeth because usually they come in
when a person is between age 17 and 25 or older—old enough to have supposedly gained some wisdom.
Wisdom teeth are commonly extracted when they affect other teeth—this impaction is colloquially known as "coming in sideways." Most adults have four wisdom teeth, but it is possible to have more or fewer.
Absence of one or more wisdom teeth is an example of hypodontia. Any extra teeth are referred to as supernumerary teeth.
