What is AGGA?
An AGGA is what is called an Anterior Guided Growth Appliance. There are two types of these appliances, a fixed one used on adults and a removable one used on children (RAGGA). Both are are used to stimulate remodeling and development of the entire midface. This not only helps with non-surgical correction of facial cosmetic issues but also for TMJ related problems too.
The appliances work by placing light pressure on the nasopalatine nerve which runs through the palate and is the growth center of the upper jaw. Each case must be carefully diagnosed and planned before treatment. A full CBCT (3D scan) can help assess the multiple facets of care from airway, tongue posture, facial bone present, and how much development is indicated.
The case above shows some changes that have occurred in an adult who had TMJ pain, airway issues, and a deficient midface with a severe overbite. The TMJ pain was addressed first with an orthotic and then an AGGA was utilized to
