The face is not only the focal point of one’s appearance, but it is also the locus of several essential functions such as eating, breathing, smelling, tasting and speaking.

A jaw that’s too small or large can mar the aesthetics of the face and can also interfere with chewing, breathing and speaking.

Orthognathic surgery repositions the jaw and maxilla (the bone supporting the upper teeth) to improve the smile and restore the harmonious proportions of the face.

In addition, maxillomandibular advancement can help treat sleep apnea.  

 Among the indications for orthognathic surgery are:  

  • A very gummy smile
  • Teeth that do not meet properly
  • Large space between upper and lower teeth
  • Small chin or receding jaw (retrognathia)
  • Large chin or protruding jaw (prognathism)
  • Sleep apnea (maxillomandibular advancement)
  • Face deviating to one side (facial asymmetry, facial scoliosis)
  • Cleft palate or cleft lip sequelae
  • Craniofacial syndrome sequelae


During your meeting with Dr. Bergeron, it is important to mention if you are experiencing problems breathing through the nostrils or if you would like to improve certain parts of your face (nose, cheeks, chin, etc.). It is possible to correct some of these problems during orthognathic surgery or to plan interventions in the best order possible.

In order to establish an optimal integrated treatment plan, you’ll meet with Dr. Bergeron and an orthodontist from his team at the same time.
