fa Iatrogenic absence of maxillary canines: Bolton discrepancy treated with mandibular incisor extraction ارتودنسی Orthodontics پژوهشي Research This case report describes the orthodontic treatment of an adult patient with iatrogenic absence of the maxillary canines, moderate maxillary and severe mandibular dental crowding, a Bolton discrepancy with a large mandibular anterior excess, a maxillary right lateral incisor crossbite, and Angle Class II molar relationships. The treatment consisted of fixed appliance therapy, mandibular incisor extraction, tooth bleaching, and dental recontouring. This method of treatment maintained the patient's good facial appearance, improved the dental esthetics, and provided a good functional occlusion, eliminating the arch length and Bolton discrepancies and providing a good outcome with minimal undesirable effects. <hr><p> <strong>Source: </strong>American Journal of Orthodontics & Dentofacial Orthopedics </p><p><a href="http://www.ajodo.org/article/S0889-5406(13)00077-2/abstract" target="_blank"><font color="#0000ff"> Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1790&slc_lang=fa&sid=1 Tassiana Mesquita Simão 10031947532846008436 10031947532846008436 No Department of Orthodontics, Dental School, Federal University of Goiás, Goiânia, Goiás, Brazil José Valladares-Neto 10031947532846008437 10031947532846008437 Yes Dental School, University of São Paulo, São Paulo, Brazil José Rino-Neto 10031947532846008438 10031947532846008438 No Department of Orthodontics, Dental School, University of São Paulo, São Paulo, Brazil João Batista de Paiva 10031947532846008439 10031947532846008439 No Department of Orthodontics, Dental School, University of São Paulo, São Paulo, Brazil
