Abstract:
Front teeth can be intruded by the segmented arches described by Burstone. The article analyses the vertical forces under the influence of symmetric intrusion arches and examines the static situation caused by non-symmetric activation of symmetric intrusion mechanics. It shows that in some cases even extrusive forces can occur in the anterior segment, whereas intrusive forces are intended to be applied.
