orthognathic
Pronunciation: or-thog-NATH-ik
Relating to surgical correction of jaw deformities to achieve proper facial proportions and functional occlusion.
Full Definition
Orthognathic refers to surgical procedures aimed at correcting dentofacial deformities that involve abnormalities of jaw size, position, or relationship. These procedures address both functional problems (such as difficulty chewing, speaking, or breathing) and aesthetic concerns related to facial proportion and symmetry. Common orthognathic procedures include Le Fort osteotomies of the maxilla, sagittal split osteotomies of the mandible, and genioplasty. Treatment typically requires coordination between orthodontists and oral surgeons, with orthodontic preparation before surgery and finishing after surgical healing. The goal is to achieve optimal facial balance, proper occlusion, and improved function. Patient selection requires careful evaluation of growth status, psychological readiness, and realistic expectations.
Usage
Usage note: Often used as an adjective (orthognathic surgery) rather than standalone noun.
