Sequential directional forces treatment: two Class II case reports.
Two types of Angle Class II, Division 1 malocclusion that were treated with Tweed-Merrifield directional forces are presented. The cases are entirely different. Each required a different diagnosis, but the results are similar. In both cases the resultant vector of all the orthodontic force systems was upward and forward in direction.
