Treatment of Skeletal Class II Malocclusion with Forsus Fatigue Resistance Appliance and Its Re-activation by Using Custom-made Crimp.

Abstract

Growing skeletal class II malocclusions with mandibular deficiency have been treated for more than a century with different types of functional appliances. Removable or fixed functional appliances are available to advance the mandible. Fixed functional appliances have the advantage of not requiring patient compliance. They can also be used concurrently with brackets. This article presents the case reports of successfully treated mild skeletal class II in late stages of puberty by using a Forsus fatigue resistance appliance along with custom made crimp.
