Class II growth modification: evidence of absence or absence of evidence?

Abstract

The capacity for dentofacial orthopaedics to modify the growth of the jaws and face in the management of Class II malocclusion has been the subject of much debate over the past century. It is only recently, following the publication of randomized controlled trials, that answers based on high level evidence can be provided. This article aims to review the recent literature in order to provide some clarification on the important issues relating to Class II growth modification, including: immediate treatment effects, long term stability of skeletal changes, the effects of differing orthopaedic appliances and the importance of treatment timing.
