Corrective Jaw Surgery

Orthognathic surgery, also known as corrective jaw surgery, aims to correct abnormalities of the jawbones in order to realign the jaws and teeth to improve overall function. This surgery can also improve the outside appearance of your face.

If you have problems with your jaw that cannot be corrected with orthodontic treatment alone, corrective jaw surgery may be considered. Your braces will be on before surgery and during recovery, until you are completely healed and proper alignment has occurred. To make sure you are getting the most out of your treatment, your orthodontist will work with your surgeon.

Corrective jaw surgery should only be performed when the jaw has completed its growth. This occurs around 14 to 16 years for females and 17 to 21 years for males.

What does corrective jaw surgery improve?

There are many benefits to corrective jaw surgery, including:

  • Improved chewing and biting
  • Correction of swallowing problems
  • Improved speech
  • Reduced wear and tear on teeth
  • Correction of an open bite, where the molars don’t touch the front teeth
  • Repaired facial imbalance, such as small chins, underbites, overbites, and crossbites
  • Improved ability for lips to close completely and comfortably
  • Relief of pain associated with temporomandibular joint (TMJ) disorder or other jaw problems
  • Repaired facial injuries or birth defects
  • Relief for obstructive sleep apnea

Where can jaw surgery be performed?

There are three sections a surgeon can work on:

  • Upper jaw
    • Receded or protruding upper jaw
    • Crossbite
    • Too much or too little of your teeth showing
    • Open bite
    • Facial growth of the middle of the face
  • Lower jaw
    • Receded lower jaw
    • Protruding lower jaw
  • Chin: Surgery of the chin can correct patients with a small chin. Small chins often accompany a severely receded lower jaw, which can cause many of the problems listed above. Typically, the altering of the jaw as well as restructure of the chin can be done in the same surgery.

History of Our Practice

Dr. Gary Cook started our practice in 1975. Dr. Cook grew up in Kent City and attended the University of Michigan Dental School. After 4 years of general practice, he sold his practice to Dr. Lee McFall in 1979, and went back to U of M to specialize in Pediatric Dentistry. Dr. Cook later returned to Grand Rapids to practice in Pediatrics.

Dr. McFall graduated from Sparta High School in 1970, Albion College in 1974 and the University of Michigan in 1978. He practiced in Sheridan, Michigan for one year as an associate before buying Dr. Cook’s practice at 9161 Sparta Avenue. In the beginning, he practiced with one chair for himself and one for a hygienist. He had 3 employees: a hygienist, an assistant and a receptionist. In 1981 Dr. McFall bought his first computer system to be used to print and track insurance claims. The practice grew and a second chair for the doctor’s patients was added. In 1985 a second computer system was installed and was still used mainly for printing insurance forms at the reception desk. The practice continued to grow and a 4th chair was added for a second hygienist. By this time there were 10 employees.

In 1995 a networked computer system was installed with a dedicated file server, and with software that could be used in the treatment rooms as well as the front desk. This computer and software system was the beginning of a long-range technology plan to completely change how the practice would deliver dental care. We began using this system at the front desk to send insurance claims electronically. At that time we were one of the first offices in West Michigan using electronic submission of insurance claims for our patients. In January of 1997 a complete remodeling of the office was done and an intraoral camera system was installed to use for patient education and for photos to send to insurance companies for our patients.

In July of 1999 Dr. Andrew Knowlton joined our practice. Dr. Knowlton graduated from Belding High School in 1991, Andrews University in 1995, and University of Michigan Dental School in 1999. In the year 2000 we placed computers in the treatment rooms to more accurately and efficiently record treatment. We were also able to schedule appointments in the treatment rooms. This shortened the amount of time it took for our patients to “check out” after treatment. At this time we had 14 employees.

The practice grew steadily between 2000 & 2004 and in October of 2004, Dr. Knowlton & Dr. McFall became equal partners. The name of the practice changed from C. Lee McFall DDS PC to Knowlton & McFall Dentistry, PLLC. In 2005 we added a 5th treatment room but by that time we actually needed even more space than the rented building had room for. In 2006 we purchased land at 9654 Sparta Ave. and began plans for a new office. The office was completed in late 2008 and is one of the most technologically advanced general practices in West Michigan. Digital records, digital x-rays, and digital photographs are all utilized in the new facility. We believe it is a beautiful and comfortable place for patients to come for their oral health care.

In 2013, Dr. McFall was searching for a dentist to replace him as he was nearing retirement.   Dr. Jordan Masson fit the bill.  Dr. Masson graduated from Lake Orion High School in 2000, Western Michigan University in 2004, and the University of Detroit Mercy School of Dentistry in 2008.  He was first hired as an associate dentist, but in July of 2014, Dr. Masson purchased Dr. McFall’s portion of the practice and officially became equal partners with Dr. Knowlton.  The name of the practice was changed from Knowlton & McFall Dentistry, PLLC to Knowlton & Masson Dentistry, PLLC.

Though our practice has evolved over the years, we remain committed to providing the best, individualized, and comprehensive care that we can for our valued patients.
