Twin Blocks

Rapid Functional Correction

Twin Block appliances are simple bite blocks that are designed for full-time wear. They achieve rapid functional correction of malocclusion by the transmission of favourable 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.

3 Months Treatment Changes

Before treatment this patient has the typical listless appearance, of many severe Class II division 1 malocclusions, evident in the dull appearance of the eyes and poor skin tone. After only 3 months treatment the patient undergoes a dramatic change in facial appearance. She appears more alert and there is a marked improvement in the eyes and the complexion.

This is a fundamental physiological change, extending beyond the limited objective of correcting a malocclusion.
