CAMPUZANO, Adriana María; SIEGERT, Michael  and  REY, Diego. Distalization with a C-DFD modified with mini-screws. A case report. CES odontol. [online]. 2014, vol.27, n.2, pp.131-141. ISSN 0120-971X.

There are currently many devices used for molar distalization when there is a Class II malocclusion; some of these devices include headgear, tooth-supported and bone-supported pendulums, the distal jet, and the sliding jig, among others. All of them have undesirable side effects. This case report aims to illustrate the results obtained by using a device with cortical and bone anchorage to treat a Class II malocclusion of a patient with a skeletal and dental class II malocclusion. A Cortical Dual Forcé Distalizer (C-DFD, a cortical-anchoring appliance designed at CES University in Medellín, Colombia was used. This device was modified by using a couple of mini-screws to reinforce anchorage, thus achieving upper distalization of molars and avoiding treatment with extractions. The C-DFD is a bone-supported distalizer that achieves a more controlled and in-body distal movement of the first upper molar, avoiding the inclinations produced by other distalizers.

Keywords : Class II Angle's malocclusion; Tooth movement; Anchoring technique; Orthodontics.
