Dental Development, Removable Appliances

Twin Block

The Twin Block is a removable appliance that utilizes acrylic blocks formed in conjunction to pull the mandible forward. Our standard Twin Block incorporates an upper mid line screw also. The phase II retainer helps retain the bite until the bicuspids have erupted into the occlusion and posterior contact is established. Twin block treatment can be done in two steps, first with an active Twin Block and second with the Phase 2 Twin Block to support the correction. After this functional appliance phase is complete, fixed orthodontic treatment is necessary for the settling of occlusion and maintenance of the skeletal correction achieved and correction of any remaining dental discrepancy. Note: When sending a Twin Block case, please be sure to provide accurate models and a bite registration to aid in accuracy.

Who Made Me:

The Twin Block appliance was developed by Dr. William Clark in the 1980s as an alternative to more rigid fixed functional appliances like the Herbst. The design features two blocks that work together to posture the mandible forward, promoting jaw growth in Class II patients. This appliance is widely recognized for its comfort and ability to achieve rapid results in growing children.
