Introduction: In the treatment of Class II malocclusion, there are several factors that must be evaluated to determine the correct diagnosis, therapy, and timing of orthodontic intervention. Case report: This case report demonstrates the result of orthodontic treatment of a 11-year-old patient with Class II, division 1 malocclusion, right subdivision, with a positive 6-mm overjet; skeletal Class II by mandibular retrusion and upper canines in infraocclusion. Due to the convex profile and severe upper and lower crowding, the treatment option chosen was the extraction of the four first premolars, allowing the resolution of crowding and placement of the canines in the correct position in the arches. Results: At the end of the treatment, the result showed an improvement in the facial profile, a pleasant smile aesthetic, ideal overbite and overjet, in addition to functional occlusion, with well-established excursive guides of man- dibular movements. Conclusion: Considering the approach possibilities, the performance of extractions with orthodontic camouflage aided by temporary anchorage devices proved to be an alternative of correct treatment, offering the patient good aesthetic and functional results.
