A Twin Block Appliance is a removable functional orthodontic appliance designed to correct Class II malocclusions by encouraging forward positioning of the lower jaw during growth. Consisting of separate upper and lower acrylic plates with interlocking bite blocks, it promotes functional jaw development while improving occlusion and facial profile.
