What is orthognathic surgery

Orthognathic surgery is also known as Corrective Jaw Surgery.  The upper jaw, lower jaw or both jaws can be repositioned to correct a malocclusion (“bad bite”) that is too severe for orthodontic correction and to achieve better facial balance and aesthetics.

 

Types of Orthognathic Surgery

  1. Upper Jaw Surgery (Le fort 1 Maxillary Osteotomy)
  2. Lower Jaw Surgery (Bilateral Sagittal Split Mandibular Osteotomy)
  3. Genioplasty (chin surgery)

 

Often, 2 jaw or combination of upper, lower jaw and chin surgery is required and is done in the one operation. 2 jaw surgery is often referred to as Bimaxillary Osteotomy.
