“…There are several appliances for early treatment of skeletal Class III, such as, Bionator (14), Frankel (FR-III) (15), chincup (16,17), Reverse Twin-Block (RTB) (18,19), Eschler appliance ("progenic appliance") (16) and protraction face mask treatment (20). These appliances treatment results depend on patient's compliance.…”

Skeletal Class III malocclusion, with its unpredictable and unfavorable nature, has been characterized by a growth pattern with doubtful prognosis regarding orthodontic mechanics, even when performed early. For a long time, Class III malocclusion was regarded as a synonym of mandibular prognathism, regardless of the affected skeletal structures. Mandibular growth, essentially determined by genetic factors, could barely be controlled by early orthodontic interventions. Therefore, the treatment choice was to wait for the patient to grow, and then make an orthodontic intervention associated with an orthognathic surgery. Maxillary involvement in the etiology of Class III malocclusion was conclusive to change orthodontic therapeutics. Maxillary intramembranous growth has a better response to orthopedic treatment, based on growth control and redirection, thus contributing for early intervention success. In several cases, excellent results have been achieved with rapid maxillary expansion and protraction. The aim of this study was to describe and discuss the treatment of a patient with Class III malocclusion, whose treatment planning comprised two phases: interceptive (mechanical orthopedic appliances) and comprehensive (fixed orthodontic appliance). The results of this case showed that Class III malocclusion should be intercepted as early as possible to permit growth redirection, mainly when the maxilla is the primary etiologic factor or dental and/or functional factors are involved. Diagnosis, treatment planning and prognosis depend on patient age, growth potential and severity of malocclusion. Early intervention, adequate indication of appliances, and patient compliance are key factors for good outcomes.

“…Realizar un tratamiento interceptivo, previene la progresión de las alteraciones (Tausche et al, 2004) y ayuda a disminuir el impacto negativo en el autoestima de los niños (Almeida et al, 2011). Por tanto, la prevención e intercepción oportuna, se considera conveniente en algunos tipos de maloclusiones, para disminuir sus consecuencias y aprovechar la capacidad de adaptación de los componentes tisulares del sistema estomatognático (Bustos et al, 2002).…”

RESUMEN:Conocer la prevalencia de las maloclusiones es esencial para el desarrollo de estrategias preventivas, las cuales deben basarse en las necesidades de la población. El objetivo de esta investigación fue determinar la prevalencia de maloclusiones en niños y adolescentes de Frutillar, entre 6 a 15 años durante el año 2012, de acuerdo a sus características oclusales. En este estudio descriptivo, se realizó un examen clínico a 184 niños y adolescentes de Frutillar, seleccionados aleatoriamente a partir del total de escolares de establecimientos educacionales urbanos. En los cuales se evaluó la presencia de apiñamiento, espaciamiento, relación molar y canina, mordida cruzada posterior, mordida abierta lateral, escalón y resalte. Los datos fueron tabulados y expresados mediante el software LibreOffice. El 96,2% de los estudiantes examinados presentó algún tipo de maloclusión, observándose con mayor frecuencia la discrepancia dentomaxilar negativa en un 67,4% de los casos. La prevalencia de maloclusiones encontrada, es mayor a la reportada por otros estudios. En Chile, existen pocos estudios publicados que revelen la real magnitud de las ADM, debido en parte a las distintas clasificaciones, diversos grupos etáreos evaluados y objetivo de cada estudio.

“…Variegated authors recommend that best time for intervention is the ending of primary dentition or early mixed dentition to provide favourable environment for craniofacial growth. Also, unrestricted growth of maxilla guides the mandible to its normal retrusive position (Almeida, 2011) 1 . Raising concerns and continued exploration have led clinicians to intervene at the earliest with one reported case of early management using reverse twin block (Sargod, 2013) 13 .…”
