Six years long term evaluation of a class II division 1 patient treated with Herbst appliance and 2 miniscrews in the lower arch as anchorage reinforcement: A case report.

BACKGROUND: Efficacy of orthopaedic treatment of class II growing patients have been reported to be partially effective, depending on appliance efficacy, patient compliance, growth spurt and other variables. Different approaches have been proposed both removable and fix, with different results, and a dento-alveolar compensation was always reported. In order to limit or avoid such dental compensation skeletal anchorage reinforcement of functional appliances have been proposed, with promising results. OBJECTIVE: The aim of the present report is to evaluate the dento-skeletal effects after 6 years of growing class II patient treated with Herbst and two miniscrews in the lower arch as anchorage reinforcement.
