fa Periodontal ligament distraction: Esthetics and occlusal stability at the 2-year follow-up ارتودنسی Orthodontics پژوهشي Research Dental distraction is an orthodontic tooth movement technique that allows closure of extraction spaces, usually of premolars, in periods from 1 to 3 weeks, by bodily retraction of the canine. This article reports on canine distalization by using a distractor device obtained from a conventional hyrax screw. The patient was an adolescent boy, aged 17 years 9 months, who came to the clinic with the chief complaint of tooth crowding. The clinical examination showed a convex profile, retroclined and protruded maxillary incisors, buccally tipped and protruded mandibular incisors, and a Class I malocclusion. The treatment comprised extractions and rapid canine distraction procedures. Pretreatment, posttreatment, and 2-year follow-up records are shown and demonstrate that dental distraction is a viable alternative of treatment. With this treatment strategy, satisfactory results were obtained without additional anchorage devices, achieving an attractive smile and optimal occlusion. The main considerations about the treatment alternatives and their clinical concerns are discussed. <hr><p> <strong>Source: </strong>American Journal of Orthodontics & Dentofacial Orthopedics </p><p> <a href="http://www.ajodo.org/article/S0889-5406(12)01232-2/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1774&slc_lang=fa&sid=1 Susiane Allgayer 10031947532846008365 10031947532846008365 Yes Porto Alegre, Rio Grande do Sul, Brazil Gabriella Rosenbach 10031947532846008366 10031947532846008366 No Department of Orthodontics, ABO, Porto Alegre, Rio Grande do Sul, Brazil Carlos Alberto Estevanell Tavares 10031947532846008367 10031947532846008367 No Department of Orthodontics, ABO, Porto Alegre, Rio Grande do Sul, Brazil Waldemar Daudt Polido 10031947532846008368 10031947532846008368 No Department of Oral and Maxillofacial Surgery, Associação Brasileira de Odontologia, Porto Alegre, Rio Grande do Sul, Brazil
