Abstract

A prospective study was conducted during 1999 among 16 children with class II division 1 Angle's maloclussion that were selected among those who seeked treatment at the Dental Teaching Clinic of Santa Clara, in 1998. All of them used the open elastic Klammt's activator-appliance, but with a different magnitude in the mandibular advance. Group 1 was composed of patients with total mandibular advance, whereas patients in group 2 presented an advance by stages. The initial teleradiographies and at a year allowed to know that in group 1 there were significant changes in the mandibular position, mandibular length and the position of upper incisors (P<0.05). These changes were more marked in group 2 (Z with a higher absolute value) and there were others as the maxillomandibular relationship, the position of the upper incisor and the inclination and position of the lower incisors in relation to the mandible. It was concluded that in both groups there were significant changes in skeletal and dental variables, but they were more marked and extensive in the group with a mandibular advance by stages.
