Head posture and dentofacial status of sixteen females and six males 12 to 34 years of age, who had been treated for scoliosis with a Boston-brace in their teens was investigated clinically and radiologically. When compared to an age and sex-matched sample the main findings were an increased craniocervical angle, particularly in frontal view; rotated orbital, maxillary and mandibular planes, a midline shift of the lower dental arch and a flattened atlas dorsal arch combined with an elongation of the dens axis. There was also a high prevalence of lateral malocclusions and developmentally missing premolars among the scoliotic patients.
