title: Design and fabrication of a modified protraction headgear for Class III long face patients.
abstract: Treatment of children with long face and with Class III malocclusions is difficult because most of the available appliances treat one of the two problems at the cost of aggravating the other one. In this article, we present the steps of design and fabrication of a modified protraction headgear that can be useful for such a patient. A patient treated with this approach is presented.
