Tooth agenesis: dento-skeletal characteristics in subjects with orthodontic treatment need

AIM: The aim of this study was to analyse skeletal, dental and arch morphology in a group of subjects with dental agenesis and to compare it with a control group. STUDY DESIGN: 2 groups of subjects were selected: an experimental group (84 patients) with tooth agenesis and a control group (84 subjects) without tooth agenesis. MATERIALS AND METHODS: Skeletal, dental, morphological and aesthetic parameters were studied using lateral and posteroanterior cephalograms and dental casts. RESULTS: Transversal and sagittal measurements showed a significant decrease in maxillary size associated with tooth agenesis in the agenesis group. No changes were observed in mandibular size. CONCLUSION: Orthodontists should consider that patients with agenesis present altered craniofacial dimensions.
