Strategic maxillary second-molar extraction in Class II malocclusion

Maxillary second-molar extraction in Class II malocclusion is a controversial issue in orthodontics. This treatment protocol is rigorous and not routine. In this case report, we present the orthodontic treatment of a patient with a Class II malocclusion, maxillary crowding, and no mandibular first molars, treated with extraction of the maxillary second molars. The mechanotherapy and indications of maxillary second- molar extraction are discussed. (Am J Orthod Dentofacial Orthop 2009;136:878-86)
