Need and demand for orthodontic treatment in an adult Swedish population.

Abstract

The prevalence of malocclusion, the need for and the demand for orthodontic treatment was studied in a randomly selected adult Swedish population > or = 20 years of age. Nine-hundred-and-twenty subjects were examined of whom 669 had their own teeth in occlusion. From those a group of 157 subjects was selected on the basis of objective need and/or subjective demand for orthodontic treatment. The various regimens of treatment required in this group were investigated. The prevalence of malocclusion ranged from 17 to 53 per cent in the various age groups. The spectrum of malocclusion was similar to that previously reported in Swedish children. The awareness of their malocclusion was higher among younger than older subjects and among those who had severe malocclusion. Objective treatment need, evaluated by two experienced orthodontists, was estimated at 11 per cent of the total population, whilst orthodontic treatment was requested by approximately 5 per cent of the population studied.
