- Abstract
AIM: The determination of the position and the size of the mandible in Class II, division 1 malocclusion is important, both in diagnosis and in treatment plan of this specific dentofacial anomaly. The aim of this investigation is the determination of the position and the size of the mandible in Greek children aged from 10 to 12 years with Class II, division 1 malocclusion, and the investigation of the possible differences between genders. DESIGN: Descriptive study. SETTING: The material of the study was collected in 1992 and derived from the archives of four orthodontic practices in Thessaloniki. MATERIAL AND METHODS: After review of the files of all the patients treated in four orthodontic practices, 136 lateral cephalometric radiographs of children aged from 10 to 12 years were selected. The radiographs came from the same laboratory and fulfilled the criteria of the study. MAIN MEASUREMENTS: The facial angle, the S-N-B angle, the S-N-Pog angle, the mandibular plane angle, the facial axis angle, the lower facial angle, the anteroposterior ramus position, the mandibular body length, and the mandibular ramus height. RESULTS: a) The mandible is retrognathic b) the length and the height of the mandibular body were found small c) the individuals of the sample of this research tend to the dolichofacial skeletal type and d) no differences were observed between genders with the exception of the mandibular ramus height which was found to be higher in boys than in girls.
