Upcoming Dr. Bromage Course at NYU

The Science Behind AGGA From the World’s Top Expert: Dr. Timothy Bromage

Obviously the Anterior Growth Guidance Appliance (AGGA) achieves amazing results. But what is the science behind AGGA?

As this appliance has blown up in popularity this past year, very little has been said about the biological mechanisms governing its operation. How the heck does it trigger such profound bone remodeling in human faces of all ages? Certainly it’s not magic.

Who is Dr. Bromage? A Brief History of AGGA Science

The only thing shrouded in more mystery than the science behind AGGA is the history behind AGGA. Of course, the two are interconnected.

For now, know this:

Scientist Donald Enlow (1927-2014) was a research scientist, not a dentist, and he is the man whose lifelong study of the biology of bone growth formed the scientific underpinning of the AGGA device. I am not completely certain but I believe that in the 1990s Dr. Enlow and Dr. Steve Gallela joined forces to produce the first AGGA.

It appears that Dr. Timothy Bromage is the chief disciple and successor of Dr. Enlow. Presently he is the world’s top expert in the biology of bone development in human faces. He often collaborates with the Dr. Gallela’s Facial Beauty Institute and may also be considered the chief research scientist behind AGGA.

He is a Professor at the New York University College of Dentistry. There he runs a research lab dedicated to the study of bone growth.

He has received numerous awards and accolades including the 2010 Max Planck Research Award for his work on the microanatomical structure of ancestral human teeth and bones.

On December 8, 2018 Dr. Timothy Bromage will be teaching a course at NYU.

The course will be about the biology behind AGGA and similar growth appliances.

It is designed for dentists but may be enjoyed by anyone drawn to the science behind these revolutionary devices. Very geeky prospective patients are welcome. I will be there.


You can register online here.

To register by phone, call (800) 346-2692 or (901) 861-0563.

The course registration fee is $897. There is an additional staff member fee is $150.

According to Dr. Bromage, “the course fee does not go to me nor to the organizers, but to a research account to keep our research laboratory open. The lab is in danger of closing in the Spring, and the course is a mechanism to raise funds to increase the possibility to keep it open.”


Here is Dr. Bromage’s own description of what will be taught:

“I was tapped on the shoulder to take Enlow's place at discussing such things to those who would listen. I suspect the program should resonate with general dentists and orthodontists prepared to see the historical contingencies that explain why we are in the predicament we are in, and how to think about growth differently.

The subjects I will cover are:

  • Craniofacial complex is just that, complex

  • Inviolate architectural relationships

  • What teeth are good for

  • What the airway is good for

  • Signals, or lack of them, in regulation of development

  • Revision of Functional Matrix Theory

My discussion will be punctuated now and then as the Facial Beauty Institute research team will step in with clinical vignettes.

I was recently asked...

I have been a big fan of Don Enlow or years.

...have read and re-read his book.

Tim, what will I learn from your course that will help me treat my patients on a practical level when I return to my office on Monday morning?

Is there a practical aspect to your presentation?

These are great questions. Here are a few points to consider.

  1. Many people have read and re-read Enlow, but do they understand it? We will have plenty of time to discuss this, should you think that your understanding may need a refresher and that understanding Enlow is helping your patients.

  2. It is the biology of facial growth we will be discussing. If you think that your understanding of the biology needs affirmation and that a better understanding of it will help your patients, then this is the course for you.

  3. If you use any form of extra-oral technology for influencing the growth of the maxilla, then a better understanding of Enlow will help you to think about how you might change the treatment of your patients.

  4. If you use any fixed or removable intra-oral appliances, you may not know the mechanisms for why they work for you. If having a better understanding of the mechanisms will help you treat your patients, then it should be a good course for you.

  5. After presenting some material on a subject, the Facial Beauty Institute research team will step in and provide their expertise in relation to orthodontic therapies consistent with the day’s discussions.
