En el presente estudio se da a conocer el tratamiento de una CII div. 1 esquelética severa. El caso clínico corresponde a un paciente masculino de 19 años con diagnóstico esquelético de CII div. 1, exceso vertical maxilar, perfil convexo, biprotrusión labial, sonrisa gingival, biproclinación y biprotrusión dental, Clase I molar y canina. Cuyo plan de tratamiento fue ortodóncico-quirúrgico con extracciones de cuatro primeros premolares, realizado en tres fases se usó aparatología con sistema Roth .018 x 0.25, y la siguiente secuencia de alambres: fase prequirúrgica .014 NiTi, .016 acero y NiTi, .016x.016 y .016x.022 Niti, .016x.022 acero de contracción en el arco inf., 16 x 22 y 17 x 25 acero y arcos quirúrgicos. Fase quirúrgica. Se realizó una cirugía LeFort 1 segmentaria con impac-tación de 2 mm y una mentoplastía de avance. Fase postquirúrgica. Arcos 17 x 25 acero, elásticos CII y de asentamiento. Paciente mejora relación esquelética y los resultados estéticos y funcionales obtenidos son notorios, alcanzándose un perfil recto por la manipulación ósea.  Conclusiones: Está en manos del ortodoncista el realizar un buen diagnóstico y dar a conocer el manejo interdisciplinario para la corrección de maloclusiones con discrepancias dento-esqueletales severas cuyo objetivo principal es buscar el máximo beneficio para el paciente.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The class II: 1 malocclusion is very common in our country, however, a correct diagnosis helps to know how to correct it. When the origin of the malocclusion is by skeletal alterations, oral functions such as breathing, deglutition, phonetics and esthetics of the patient are affected. In this study, the treatment of a class II: 1 severe skeletal malocclusion is presented. A case of a 19-years-old male patient is presented, with a skeletal diagnosis of class II: 1, maxillary vertical excess, convex profile, biprotrusive lips, and gingival laugh, dental protrusion and class I molar and canine. The planted treatment was surgical and orthodontic, carried out by means of extractions of the four first bicuspids, in three phases using Roth system .018/.025, and the following sequences of wires: pre surgical phase; .014 NiTi, .016 steel and NiTi, .016/.016 and .016/.022 NiTi, .016/.022 steel of contraction in lower arch, 16/22 and 17/25 steel and surgical arch. The surgical phase consisted on one surgical act, a LEFORT 1 segmentary with two millimeters of impact was carried out, as well as a genioplasty. The post-surgical phase consisted on using arch 17/25 of steel, elastic class II and seat bite. The patient obtained a better skeletal harmony and the esthetic and functional result were visible after the treatment, obtaining a straight profile by the surgical procedures.  Conclusions: It is very important for the orthodontist to carry out a good diagnosis and to provide an interdisciplinary management to correct malocclusions with severe teeth-skeletal discrepancy, looking for a maximum benefit for the patient.]]></p></abstract>
