Behavior of the mandibular length in class II non-growing patients treated with jaw functional orthopedics

Class II treatment is the leader of seeking for dentofacial correction in offices all around the world due, mainly, to facial esthetics impairment caused by this malocclusion. Mandibular forward repositioned is needed for the majority of this treatment. Jaw Functional Orthopedics (JFO) is a recognized protocol to treat Class II in growing patients. The aim of this investigation is to study the behavior of mandibular length in class II non-growing patients treated with JFO. Distance between Gonion and Mento were measured in lateral teleradiographs at T0 and T1 (from 18 to 21 months of treatment) of non-growing class II patients under treatment with JFO and mandibular supplementary growth was found (P = 0,006). In the sample studied jaw functional orthopedics showed to be efficient to correct the overjet in class II non-growing patients. Mandibular advancement with functional orthopedic appliances promotes a supplementary mandibular growth in non-growing patients. Further studies are necessary for a better comprehension of the subject.
