Indications for Orthognathic Surgery


Orthognathic surgery (OS) is a surgical intervention that alters relationships of the jaws and dental arches.

The treatment involves a combination of orthodontics and maxillofacial surgery.

It is used to correct dentofacial deformities that cannot be treated with acceptable results by conventional orthodontics.

The first description of a surgical intervention to correct a malocclusion was by Hullihen in 1849.

The most frequently used surgical procedures for correcting the relationship of the jaws are Le Fort I osteotomy and sagittal ramus split osteotomy.
