The first 100 cases of orthodontic treatment: one year out of retention

N A Fox et al. Dent Update. 1994 Sep.

Abstract

The Index of Orthodontic Treatment Need (IOTN) and Peer Assessment Rating (PAR) Index have been developed to assess need and outcome of orthodontic treatment. In this paper the authors evaluate the occlusal change and orthodontic treatment need of 100 consecutively started courses of orthodontic treatment at least 1 year after all retention measures had ceased using these indices.
