Innovation in Skeletal II Treatment Including Effective Incisor Root Torque in a Prelimary Removable Appliance Phase

Abstract

A new removable appliance design is presented which offers the possibility of significant palatal movement of the maxillary incisor roots and which is capable of producing marked changes in the position of the root apices. Heavy extra-oral forces may be applied through the appliance to the entire maxilla to orthopaedically change the facial growth pattern and ameliorate the Skeletal II problem, with the torquing movements being carried out concurrently. A second phase of Edgewise treatment, often with directly bonded transparent plastic brackets, is then carried out to complete the correction. This stage is much reduced in complexity and may be confined to alignments and detailing of the occlusion over a relatively short period of time.
