Class II skeletal is one of the major challenges to be treated by the orthodontist. This occurs when there is a discrepancy between the maxilla and mandible, ie may have an overgrowth of the maxilla accompanied by a retrusion of the mandible. This causes both skeletal and dental alterations, presenting crowding, labial incompetence or convex profile and may be strictly orthodontic treatment or in certain cases require maxillo facial surgeries. The objective of this research was to improve the patient's profile, achieving Class I molar and canine, correct lip incompetence and improve occlusion. The treatment plan included tooth extraction first upper and lower premolars and thanks to the implementation of the ROTH technique using elastic chains and arches retraction could meet the initial objective, improving the aesthetics and function of the dento structures facial.

Palabras clave : malocclusion; dental extraction; jaw; dental occlusion.
