Prognathism: From Causes to Treatments

A Smile Can Change Everything

Prognathism
  • Koch Orthodontics
  • | Sep 22, 2020
Prognathism is a condition affecting the structural abnormality of a person’s face due to a significant protrusion of either of the jaws. It ideally leads to the teeth of either the upper jaw or the lower jaw to cover the other set of teeth which adversely hinders breathing, appearance, speaking, biting and chewing. Prognathism especially makes children prone to long-term difficulties with speech. For instance, it may cause a noticeable lisp or an inability to pronounce certain words correctly. The condition also hinders the growth of permanent teeth and influences them to grow at an unhealthy angle.There are three principal types of prognathism commonly occurring:

  • Mandibular prognathism or overbite signifies lower jaw protrusion
  • Maxillary prognathism or underbite denotes upper jaw protrusion
  • Bimaxillary prognathism causes both upper and lower jaw to protrude

Orthodontic intervention becomes essential to reverse the damage done by these distinct types of prognathism. Orthodontic treatments offer an ideal solution to a variety of misalignment problems and can help overcome lasting problems caused by them.

Causes of Prognathism

One of the reasons for the occurrence of prognathism is a genetically inherited abnormally protruding jaw. The other probable reason could be an underlying medical condition directly affecting jaw health, such as:

  • Acromegaly, excessive production of growth hormone in a patient’s body leading to enlarged tissues of their lower jaw
  • Basal cell nevus syndrome, an inherited characteristic or Crouzon syndrome which is marked by premature fusion of skull bones, giving rise to the abnormal and unhealthy jaws
  • Acrodysostosis affects bone growth, and people suffering from this condition tend to have smaller bones all over their body, making other bones disproportionate.

When to see your doctor?

You don’t have to worry about any of the prognathism, be it mandibular, maxillary or bimaxillary if your extended jaw naturally fits the shape of your face since birth and isn’t influencing other problems in your bite or speech.

In case your prognathic jaw starts to attract any extreme dental problems for you and causes unbearable pain, consult your general dentist, orthodontist or an oral surgeon at the earliest. They will be able to guide you towards an appropriate treatment option which suits your needs.

How can it be treated?

In order to effectively treat malocclusion or misaligned jaws due to prognathism, dental experts generally recommend a combination of maxillofacial surgery and orthodontic treatment. While the surgical procedures include Sagittal Split Ramus Osteotomy and Intraoral Vertical Ramus Osteotomy, a conventional orthodontic treatment like braces could also prove to be useful. Distal Osteotomy is another surgical method, often chosen due to its additional long-term positional stability.

During the procedure, to avoid any surface incisions or scars, your surgeon will make interior cuts on your gums for a better excess to the jaw. They will cut and shift the bone as required and then, instead of wiring, your jaws will be held together with small plates and screws guiding to permanent relocation of the jawbones and bite correction. If your case needs a combination procedure for correction, your surgeon or orthodontist might suggest you wear braces before and after the surgery to achieve more regular teeth alignment.

Are you experiencing any of the symptoms of misaligned jaws? Consult your healthcare provider soon. With this article, we aimed at providing you with a brief understanding of prognathism and its various aspects. If not treated promptly, this harmful condition leading to protrusion of either upper, lower or both of your jaws could lead to a variety of oral health problems lasting a lifetime. To gain a proper realignment, you might have to undergo corrective surgery along with orthodontic treatment.

Deanna P.
I decided to get braces on again for cosmetic reasons after about 20 years. I went to a few places for consultations, and ultimately chose Koch Orthodontics based on the clean office, welcoming staff, and great online reviews. I’m about a year through my treatment and I was getting a discouraged I was not going to get my “dream smile” I had envisioned in my head. I asked to make an appointment with my doctor and Dr Koch to talk me through my concerns and go over the rest of my treatment. Initially, everyone’s schedule wasn’t lining up until after my braces were supposed to come off (in 3 wks) which left me kind of bummed. However, the next day, I received a phone call from a lady named Ashley saying Dr Koch wanted to review my plan with my Dr (Gass) and can get me in for an appointment the next day. It was then I knew I picked the right orthodontist. Not only were my concerns listened to, openly discussed with me, and thoroughly reviewed with my current treatment plan by both Dr. Gass and Dr Koch, they really made me feel like they wanted the best for my smile. I truly appreciated the effort of everyone involved making sure I’m happy with my outcome. I can honestly recommend this orthodontist now.

And continuously, the two best techs I’ve had are Johnny and Devonte. Shoutout to them!
Response from the owner:Hi Deanna! Thank you so much for sharing this! We’re so glad Dr. Koch, Dr. Gass, and Ashley could put your mind at ease and make sure you feel confident in your smile journey. And Johnny and Devonte will love the shoutout, they really are the best!

Amina B.
I’ve had such a great experience with my orthotist and aligner journey! From the very beginning, everything was explained clearly and I always felt comfortable and informed. The aligners have been easy to use, and I’ve already noticed such a positive difference. My orthotist has been supportive, attentive, and genuinely cares about my progress. Appointments are always smooth, and I never feel rushed.

Overall, I’m really happy with the results so far and would definitely recommend both the aligners and my orthotist to anyone considering treatment.
Response from the owner:Hi Amina! Thank you so much for sharing your experience! We’re thrilled to hear that your aligner journey has been smooth and that you’ve already noticed such a positive difference.
