What are Anterior Growth Guidance Appliances (AGGA)?
Anterior growth guidance appliances (AGGA), also known as osseo restoration devices, controlled arch braces (CAB), and advanced lightwire functionals (ALF), are orthodontic appliances marketed for treating craniofacial pain, TMD, and sleep apnea.
However, widespread clinical evidence demonstrates that these devices can cause profound harm to patients. Mainstream orthodontists have debunked their claims of stimulating bone growth as scientifically unproven.
The Mechanics of AGGA Damage
Rather than stimulating bone growth, AGGA and CAB devices apply force that pushes teeth out of the supporting alveolar bone. This combination frequently results in:
- Severe Root Structure Resorption: The pressure weakens tooth roots against maxillary bone.
- Periodontal Bone Loss: Rapid bone breakdown surrounding anterior teeth.
- Loosened Teeth & Tooth Loss: Teeth become unstable, causing chronic pain and requiring surgical extraction or dental implants.
Legal Recourse for Dental Device Malpractice
Patients who have suffered dental trauma, chronic nerve pain, or tooth loss due to unproven orthodontic expansion devices may be entitled to substantial compensation for corrective surgery, dental implants, and pain.
