Types of Jaw Surgery

Posted on 6/3/2024 by Office
A person holding their jaw in painSometimes, a misaligned bite can be more than just a cosmetic concern. It can lead to difficulty chewing, speaking, and even jaw pain. Orthognathic surgery can correct these issues by repositioning the jawbone. There are several types of jaw surgery, each designed to address a specific problem. Here is a closer look at three common procedures:


Genioplasty, or chin surgery, is a procedure aimed at enhancing the appearance and function of the chin. This surgery is typically performed to correct a receding or protruding chin, resulting in improved facial harmony and profile. Genioplasty may involve reshaping the chin bone or augmenting it with implants to achieve the desired aesthetic outcome.

Maxillary Osteotomy Surgery

Maxillary osteotomy or upper jaw surgery corrects dental misalignments such as excessive overbites, crossbites, and open bites. An oral surgeon makes an incision in the gums to access the upper jaw, then carefully cuts and repositions it into proper alignment. This addresses issues like a receding jawline or irregular tooth appearance. To maintain the corrected position, a small plastic wafer is attached to the teeth, while titanium screws and metal plates secure the jaw firmly in place.

Mandibular Osteotomy

Mandibular osteotomy, commonly referred to as lower jaw surgery, is a procedure aimed at correcting severe underbites by meticulously repositioning the lower jawbone. This surgical intervention, typically performed after orthodontic treatment, involves making an incision behind the teeth to access the jawbone. The jawbone is precisely cut and shifted forward or backward to achieve the desired alignment through this incision. Titanium screws and plates are then used to secure the jaw in its new position, ensuring stability and support. Finally, the incisions are closed, completing the procedure to improve both function and aesthetics.

We will assess your needs and recommend the most suitable procedure to achieve optimal results.
