Orthognathic (Jaw) Surgery & Treatment of Facial Deformities

Corrective Jaw Surgery for Overbites, Underbites, and Crossbites

Orthognathic (jaw) surgery is needed when jaws don’t meet correctly and/or teeth don’t seem to fit with jaws. Teeth are straightened with orthodontics and corrective jaw surgery repositions misaligned jaws. This not only improves the facial appearance but also ensures that teeth meet correctly and function properly.

Orthognathic Surgery Presentation

Who Needs Orthognathic Surgery?

People who can benefit from orthognathic surgery include those with an improper bite or jaws that are positioned incorrectly. Jaw growth is a gradual process and in some instances, the upper and lower jaws may grow at different rates. The result can be a host of problems that can affect chewing function, speech, breathing, long-term oral health, and esthetic appearance. Injury to the jaw and birth defects can also affect jaw alignment. Orthodontics alone can correct bite problems when only the teeth are involved. Orthognathic surgery may be required for the jaws when repositioning in necessary.

Difficulty in the following areas should be evaluated:

  • difficulty in chewing, biting or swallowing
  • speech problems
  • chronic jaw or TMJ pain
  • open bite
  • protruding jaw
  • Retrusive chin
  • Concerns about esthetic facial appearance- See Section on Cosmetic Facial Surgery
  • Breathing problems- In our practice, all jaw surgery patients are comprehensively assessed (Volumetric CT scan, naso-pharyngoscopy, etc.) for airway obstructions that may be treated in conjunction with jaw surgery. Jaw relationships impact multiple levels of the upper airway. See section on snoring and Sleep Apnea.

Comprehensive Treatment of Jaw and facial deformities

Facial/Jaw deformities result in multi-factorial problems and dysfunction. Dr. Gilbert’s unique training and diagnostic approach to your care can comprehensively and concomitantly address the following;

  • Correction of bite and jaw harmony (upper and lower jaw relationship)
  • Optimization of function (Chewing, speech, TMJ function)
  • Facial esthetics. Frequently, facial esthetic surgery is combined with jaw surgery. (lips, nose, chin, cheeks, brows and eyelids, facial wrinkles)
  • Optimization of the upper airway (nasal septum and turbinates, nasopharynx, oropharynx, hypo-pharynx)

Any of these symptoms can exist at birth, be acquired after birth as a result of hereditary or environmental influences, or as a result of trauma to the face. Before any treatment begins, a consultation will be held to perform a complete examination with x-rays. During the pre-treatment consultation process, feel free to ask any questions that you have regarding your treatment. When you are fully informed about the aspects of your care, you and your dental team will make the decision to proceed with treatment together.

Technology and Orthognathic Surgery

Dr. Gilbert uses modern computer techniques and three-dimensional models to show you exactly how your surgery will be approached. Using comprehensive facial X-rays, 3 dimensional CT scans, and computer video imaging and analysis, we can show you how your bite will be improved and even give you an idea of how you’ll look after surgery. This helps you understand the surgical process and the extent of the treatment prescribed. Our goal is to help you understand the benefits of orthognathic surgery.

Dr. Gilbert was among the first U.S. surgeons to utilize computer-aided surgical simulation in the planning and execution of orthognathic surgery. This technological advancement facilitates optimal functional and esthetic surgical outcomes.

Patient Testimonial

I donated bone marrow in 2007 and experienced what every person in this country should experience.......first rate care, compassionate doctors, nurses and support staff.......it was great. Fast forward to Dr. Gilbert's office 2019 and this is exactly what I experienced once again. I had a consultation prior to my surgery and Dr. Gilbert sat down and really listened to what I had to say with regard to my issues, fears and concerns regarding surgery. I never felt, as I've felt with other doctor's, that he wanted to be somewhere else. He made me feel like I was the most important patient at that time. Dr. Gilbert's calmness and confidence really allowed me to put my complete trust in him, not easy for me to do. He told me I probably would not have any pain, maybe soreness, but no pain. He was spot on in that regard. His staff is top notch and friendly and answered whatever question I threw at them. I wish all medical interactions were as great as this has been!

Every time that I have gone to Dr. Gilbert's office, I have been treated as family. His staff are exceptionally friendly, as well as professional. The facility has "state of the art" technology, and the atmosphere is one of caring concern! Regardless of the issue that brought you to see an oral surgeon, you leave reassured that you are in the best possible hands. Dr. Gilbert is knowledgeable, and kind, always making you feel confident in his care. (And the dimples are an added benefit). Gloria, Dr. Gilbert's PA, is genuine, proactive and a real advocate! Thanks you Inland Institute!
