Historical Background and Controversy of AGGA Device
The Anterior Growth Guidance Appliance (AGGA) has a distinguished history of innovation and conflict. Dr. Steve Galella created the device in the 1990s to expand adults’ jawbones without surgery. However, the AGGA has faced legal disputes and safety concerns, leading to critical scrutiny from various dental communities.
Development
AGGA’s evolution in orthodontics has been notable, attracting attention for its unique approach to dental correction. The device resembles a retainer and uses springs to apply pressure to the front teeth and upper palate, intending to expand the jaw and improve facial appearance and breathing issues. However, dental specialists have criticized the device, stating that it doesn’t grow or widen the jaw but instead pushes the teeth out of their original position.
Controversies
The AGGA device has been the subject of multiple lawsuits, with patients alleging that it caused significant harm, including damaged gums, eroded bone, and tooth loss. The device was never submitted for FDA approval, and its safety and effectiveness have not been established. The FDA is currently evaluating safety concerns related to the AGGA and other similar devices.
Rebranding
Following controversies, the AGGA has been rebranded as the Osseo-Restoration Appliance. Despite the rebranding, the device continues to face legal challenges and scrutiny from dental professionals.
Understanding the Anterior Growth Guidance Appliance (AGGA)
The Anterior Growth Guidance Appliance (AGGA) is a dental device designed to stimulate jaw growth. It features components that apply targeted pressure to the upper palate, which include wires and a small acrylic oval. These components play crucial roles in the adjustment and expansion of the dental arch.
Mechanisms of AGGA
The AGGA works by applying constant pressure to a small part of the middle of the palate. This pressure is believed to stimulate bone growth, although the exact mechanism is not fully understood and has been a subject of debate among dental professionals. The device is connected to the back teeth and pushes the front teeth forward, which is thought to encourage the jaw to remodel forward.
Components of AGGA
The AGGA consists of molar bands that secure the device to the back teeth, springs that create a gap between the canine teeth and the teeth behind them, and wire and pads that apply forward pressure to the palate and upper front teeth. The device also includes a small acrylic oval, which is the key component that applies pressure to the palate.
AGGA in Practice
The AGGA is used in orthodontics to improve the function of the bite and temporomandibular joint, improve breathing patterns, and create a cosmetic smile. It is also used as part of an orthodontic treatment plan to open spaces that may have closed after tooth extraction in preparation for braces.
However, it’s important to note that the AGGA has been associated with several documented cases of poor treatment outcomes, including severe mouth pain, tooth loss, and disfigurement of the mouth. There have been multiple lawsuits filed against the inventor of the appliance, Dr. Steve Galella, and his Facial Beauty Institute.
Alternatives to AGGA
There are other adult palatal expander appliances that exist, including the DNA appliance (Vivos), ALF, and Homeoblock devices. These appliances are removable and have proven track records with completely different mechanisms of clinical action.
For instance, the DNA appliance encourages three-dimensional growth of the jaw and face bones in adults, which is more flexible than the AGGA’s one-dimensional forward growth.
While the AGGA has been in wide use for years, it has drawn criticism from many orthodontists and other dental specialists due to its unproven and unpredictable track record. It’s crucial for patients to fully understand the potential risks and benefits of using the AGGA and to consider other proven alternatives. Always consult with a trusted dental professional before deciding on any orthodontic treatment.
AGGA Treatment Phases
The Anterior Growth Guidance Appliance (AGGA) treatment is a unique orthodontic procedure that aims to shape the growth of the jawbones and the entire facial structure. This treatment is divided into two main phases: the growth phase and the controlled arch braces phase.
Growth Phase (About 1 year)
The growth phase is the initial stage of the AGGA treatment. During this phase, the AGGA device is cemented to the upper teeth. This device is designed to stimulate the body’s natural ability to repair bones in response to trauma, microtrauma, and soft tissue irritation. As a result, even in adults, the body reacts to soft tissue stimulation by moving the bones of the facial skull.
The AGGA device is adjusted monthly for optimal palate expansion. This adjustment process is crucial as it encourages the expansion of the palate or the arch on the inside of the mouth.
Key Points of the Growth Phase:
- Cementing of AGGA to upper teeth
- Monthly adjustments for optimal palate expansion
Controlled Arch Braces Phase (About 1 year)
Following the growth phase is the controlled arch braces phase. During this phase, the AGGA device is removed, and full braces are implemented for comprehensive dental alignment.
The purpose of this phase is to ensure that the changes made during the growth phase are maintained and further enhanced. The braces help to align the teeth properly and maintain the expanded palate’s shape.
Key Points of the Controlled Arch Braces Phase:
- Removal of AGGA
- Implementation of full braces for comprehensive dental alignment
It’s important to note that while the AGGA treatment has been praised for its potential to reshape the jaw and facial structure without surgery, it has also been associated with serious complications. Some patients have reported severe mouth pain, tooth loss, and disfigurement of the mouth following the treatment. Therefore, it’s crucial to thoroughly discuss the potential risks and benefits with your healthcare provider before deciding to undergo this treatment.
Comparisons with Other Orthodontic Appliances
The Anterior Growth Guidance Appliance (AGGA) is a dental device designed to stimulate jaw growth. It differs from other devices like the DNA appliance, ALF, and Homeoblock, which use removable components and different pressure mechanisms.
Differences
AGGA operates differently from devices like the DNA appliance, ALF, and Homeoblock. A fixed appliance called AGGA applies targeted pressure to the upper palate. The DNA, ALF, and Homeoblock appliances, on the other hand, can be taken off and use light springy pressure to help bones grow. For instance, the DNA appliance encourages three-dimensional growth of adult jaw and facial bones, providing a more flexible approach than the AGGA’s one-dimensional forward growth promotion.
Advantages/Disadvantages
While AGGA is unique in its approach, it also carries specific drawbacks, particularly in terms of cost and treatment duration. The AGGA has been associated with several documented cases of poor treatment outcomes, including severe mouth pain, tooth loss, and disfigurement of the mouth. On the other hand, devices like the DNA appliance, ALF, and Homeoblock have proven track records and are generally considered safer alternatives.
AGGA stands out for its unique approach to dental correction, but it also has its drawbacks. Patients considering orthodontic treatment should consult with a dental professional to discuss the potential risks and benefits of AGGA and other orthodontic appliances.
