Abstract

The twin blocks are a system of functional apparatuses that incorporate the use of blocks of upper and lower bites, reposition the mandible and transmit the favorable occlusal forces to the inclined planes covering the posterior tooth. A prospective study was undertaken in a sample of 13 patients aged 11-13 that presented permanent dentition, class II division I malocclusion, and that were treated with conventional twin blocks apparatuses. After 6 months, favorable facial changes were obtained in all the evaluated parameters. Most of the patients that presented a convex profile, attained a straight profile. A functional bilabial closure was achieved in 92.31 % of the patients. The nasolabial angle increased significantly and the protrusion of the inferior lip varied from 0.26 to 1.03 mm, which was highly significant from the statistical point of view.
