Twin Block

Twin Block

The Twin Block is an appliance in two halves; one for the upper jaw and one for the lower jaw, each half have an inclined plane, possibly also an expansion screw for widening the jaws and springs or mini screws for adjusting the individual position of teeth..

Twin Block appliances achieve rapid functional correction of malocclusion by the transmission of favorable occlusal forces to occlusal inclined planes that cover the posterior teeth. The forces of occlusion are used as the functional mechanism to correct the malocclusion. When the patient bites together the upper plane pushes the lower plane and so the lower jaw forwards.

The Twin Block can correct distal bite, correct the deep bite, expand the tooth arch and correct individual tooth position.
