What is The AGGA Anterior Growth Guidance Appliance?
The AGGA is an appliance that in certain cases can promote forward growth but that is about it. The device usually needs to be followed by braces and other appliances to straighten the teeth and attempt to position the lower jaw. The AGGA cannot expand the width of the upper jaw. And this later deficiency is probably the largest pitfall of the appliance. We do not use this appliance at the TMJ Sleep and Breathe Center.
For adult palatal expansion Dr. Adams often uses the DNA or Homeoblock appliance. The AGGA is becoming increasing associated with negative case outcomes and is waning in popularity. The DNA appliance and Homeoblock are capable of three dimensional growth and capable of starting and finishing many cases with complaints of TMJ or sleep apnea. The AGGA, on the other hand may get growth in one direction, but sets the patient up for a series of other expensive and time consuming appliances. Cases with the AGGA typically last 3-5 years and cost over $30,000. We have not been impressed with the results we have seen.
The AGGA is a Fixed Appliance
The AGGA is a fixed appliance that stays in the mouth all the time like braces. It cannot be removed by the patient. It collects food during eating. The appliance is not very useful for treating patients who have TMJ pain because it leaves them biting on their teeth. Many dentists use a lower splint at the onset of treatment called a Gelb appliance. We do not agree with this treatment as the repositioning performed by the Gelb is arbitrary and not done in concert with forward growth of the upper jaw.
How Does the AGGA get Anterior or Forward Growth?
Dr. Galella is the inventor of the AGGA. He believes the AGGA appliance stimulates a special spot on the roof of the mouth that triggers the body’s bone-building response. Namely a nerve on the palate. The pressure creates a rapid bone growth event throughout the entire head and face area. Dr. Galella created the Controlled Arch System. His mainly focuses on facial cosmetic and growth. Dr Galella is the founder of the Facial Beauty Institute. Galella is also involved with OrthoMatrix Corp.
