Frankel Appliance
The Frankel Appliance is a removable functional orthodontic device designed for adolescent patients. It guides jaw development and aligns teeth by redistributing muscle forces and soft tissue tension. As a non-invasive solution, it not only corrects bite discrepancies but also enhances overall facial aesthetics, making it a classic choice in functional orthodontics.
