Orthognathic surgey includes surgical correction for an abnormal bite and jaw relationship.  These cases are usually coordinated with an Orthodontist for an optimum outcome. The results are not only a functional improvement, like mastication, speech and airway, but also aesthtics.


Dr. Momtaheni contibuted to an Oral Surgery Textbook "Modern Practice in Orthognathic Surgery, Chapter in Sleep Apnea,. W.B. Saunders, 1992.  There he advocated and presented a case of a middle age man with Obstructed  Sleep Apnea who was treated with Orthognathic Sugery.  Twenty-three years later, this technique is used all over the world for the treatment of Obstructed Sleep Apnea. 

What makes our services special is 35 years experience, in office capability to obtian 3D imaging of jaw deformities and analysing the outcome before the surgery. Dr. Momtaheni, along with his colleague Dr. Joseph Hung, are pioneers of performing orthognatic surgeries with Invisalign alone. This will bypass the need of braces. Thus, patients with laminates and/or other cosmetic dental restorations, or who do not desire the unaesthetic and hygiene requirements that come with braces, can utilize this procedure.  For further information, please contact our office


Credential:  Dr. Momtaheni has been one of the pioneers of Orthognathic Surgery in the United States.  He and his colleques have developed a concept of "Mini Residency Program" over 30 years ago to teach other surgeons the techniques and knowledge to perform these procedures.  In 1985 and 1986 Dr, Momtaheni lectured on " A Safe and Predicable Technique for Multi-Piece Maxillary Osteotomies" for the National Annual Meeting of the American Association of Oral and Maxillofacial Surgeons.  In addition, he has been teaching Reidents at Columbia Presbyterian and Beth Israel Medical Centers for the past 29 years.




Dr. S.I. from Westchester, NY wrote in Yelp:


I have been meaning to write this review for a long time.  I, myself, am a dentist who consulted Dr. Momtaheni to correct my bite and to improve my esthetics after years of bruxism and jaw clenching led to tooth wear and hypertrophy of my facial musculature.Prior to visiting Dr. Momtaheni, I sought the opinions of two other oral surgeons, both of whom claimed that there was no solution to my problem, and that they wouldn't be willing to perform the surgery since it was "too risky."I also spoke with two orthodontists, who also maintained that there was no true fix for my chief complaint.On a whim and as a last ditch attempt, I researched Manhattan orthodontists online and scheduled an appointment w/ Dr. Joseph Hung.  Dr. Hung evaluated me and referred me to Dr. Momtaheni's office, since he knew he was adept at handling the most complex surgical cases.After a full workup, Dr. Momtaheni gave me some incredibly exciting news.  He would be able to correct my jaw relationship with orthognathic surgery, as well as address a few of my facial esthetic concerns.A date was booked, and I underwent double jaw surgery.  In the days and weeks leading up to my surgery as well as the weeks after the surgery, Dr. Momtaheni and his staff were readily available to answer all of my questions.  They did a fantastic job at putting me at ease.  They even offered to have one of their nurses stay overnight in my apartment the night immediately after the surgery to ensure that any possible post-operative issues would be relayed to Dr. Momtaheni right away. The procedure went very smoothly with no complications.  The final result was and is outstanding.  To say that my appearance improved is quite the understatement.  This was indeed a life changing experience.  I have zero regrets and am so fortunate to have met and know Dr. Momtaheni not only as a patient but also as a professional colleague.His professionalism, kindness, attention to detail and expert surgical skill truly warrant the highest praise.He is one of the top, if not THE TOP, oral and maxillofacial surgeons in the country.  I truly hope those who read my words take them to heart and speak to him personally about any of their facial concerns.He has the potential to change your life in the most positive way possible


Frankie M. from Staten Island, NY wrote in Yelp:

“Dr. Momtaheni was our third opinion for my son's medical issue.  My son was in pain with many other symptoms including impending permanent damage to his face, teeth, jaw etc.  We went to two doctors before getting a recommendation for Dr. Momtaheni.
As soon as we started discussing my son's condition we both knew this was the most competent doctor for the complicated procedure.  But, I also checked him out online and saw his outstanding credentials and experience in the field. 
Our visits were thorough, informative and professional.  I researched the surgical procedure myself beforehand.  Dr. Momtaheni explained everything regarding the procedure with a presentation including clear visual and comprehensive explanations.
We left his office knowing we were in good hands.  At the hospital he was with us pre op, and post op.  He also came to me in the waiting room to fill me in on how the procedure went and how my son was doing. 
I am satisfied and relieved to have found this doctor.  I highly recommend Dr. Momtaheni.  Get your two or three opinions and then see what Dr. Momtaheni has to say.  He is by far the most competent in his field.”

Our daughter Sara has been under Dr, David Momtaheni’s care for the past year.  She has had a complete restructuring of her jaw, both top and bottom.  We have had a wonderful experience with Dr. Momtaheni.  His bedside manner is impeccable, and his compassion for his patients and their families is exemplary.  At no time during this process did Sara feel any consternation or concern about what Dr. M. was going to do, as he explained everything to her and to us in a very understandable manner, and there were no surprises along the way.  Dr. Momtaheni is a truly amazing individual and amazing surgeon, for not only has he changed this girl’s life by restructuring her jaw, but by how he put everyone at ease, both prior to and following the surgery.
