FERNANDEZ YSLA, Rebeca et al. The twin blocks: Use and construction of the conventional appliance . Rev Cubana Estomatol [online]. 2005, vol.42, n.3, pp. 0-0. ISSN 1561-297X.

The twin block technique was developed by the Scottish Dr. Clark during the 1980s. These appliances reposition the jaw and redirect the occlusal forces. They are constructed in protrusive bite that allow to efficiently modify the occlusal inclined plane by means of plastic or acrylic inclined planes placed on the blocks of occlusal bites. They are comfortable and they should be used all the time, including the meal time in order to foster the protrusive mandibular function. The treatment has 2 stages: an active one, where the overjet and the overbite are corrected, and the support or maintainance stage that guarantee the stability of the results. Fantastic results are attained by using the conventional appliance in the treatment of class II division I malocclusion in relatively short periods of time.
