Abstract
The purpose of this study was to determine the dentoalveolar response of class III patients in the mixed and late mixed dentition phases fitted with a protraction mask and expansion. The before and after cephalometric records of 74 patients divided by sex were analyzed at ages 6 to 9 and 9 to 12 years to assess the dentoalveolar changes. Data was correlated by means of paired t tests and Scheffe´s multiple contrasts. No significant changes were seen in all dentoalveolar relationships between the ages of 6 to 9 years and 9 to 12 years and between males and females. Maxillary teeth tended to be proclined, while mandibular teeth to become retroclined.
