Objectives<\/b>  The objective of this clinical case is to describe a patient with a class I skeletal, molar class I, who exhibited increased overbite and dental overcrowding prior to treat\u00adment. This case was solved during mixed dentition by using only an activator. <\/p>\n

Materials and methods  <\/b>A healthy Caucasian girl of eight years was clinically examined at the Dental Clinic of the University of L\u2019Aquila. The diagnosis was a skeletal class I, molar class I, ex\u00adhibiting an overbite of 7 mm prior to treatment, atypical swallowing. The patient showed a medium grade of dental crowding in both dental arches.<\/p>\n

The patient was only treated with the EQ O.S.A. device, which was replaced two times after six months, during two years of orthopaedic-functional orthodontic therapy. This patient was under treatment until full per\u00admanent dentition was completed.<\/p>\n

After taking alginate impressions and developing cast stone mod\u00adels, the orthodontist uses an ap\u00adpropriate ruler to measure the dis\u00adtance between the palatal cusps of the first upper bicuspids (or the first upper deciduous molars) and will choose the correct size among the following:            <\/p>\n
