Tooth agenesis: dentoskeletal characteristics in subjects with orthodontic treatment need

The aim of this study was to analyse skeletal , dental and arch morphology in a group of subjects with dental agenesis and to compare i t wi th a control group. S S t tu ud d y y d de es s i i g gn n T wo groups of s ub j ect s were s el ected: an ex peri mental group ( 84 pati ent s ) wi th tooth agenes i s and a control group ( 84 s ub j ect s ) wi thout tooth agenes i s. M Ma at te er ri iSkeletal , dental, morphological and aesthetic parameters were studied using lateral and posteroanterior cephalograms and dental casts. 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. Orthodontist should consider that p
