Abstract

Posttreatment changes are further complicated by the slow continued growth that occurs after treatment into adulthood. The purpose of this study was to examine long term posttreatment changes. The lateral cephalograms of 51 Caucasian females treated in the standard Edgewise practice of one private practitioner in Cookeville, TN were examined to investigate changes in the cranial base, nasomaxillary complex, mandible, interach relationships, dental relationships, and the soft tissue integumental profile that occured an average of 23 years posttreatment. Two tailed t-tests (α = 0.05) were run to see whether the posttreatment changes was statistically significantly different from zero. Craniofacial growth continued after treatment, though subtle compared to that seen in other studies, which is probably because this study was exclusively females. Dentally, there was a remarkable stability with no clinically significant orthodontic relapse.
