fa Orientation of the occlusal plane in a Class I adult population جراحی دهان، فک و صورت Oral and Maxillofacial Surgery پژوهشي Research <p> <strong>Objective</strong></p><p>  To primarily evaluate whether Delaire's ideal occlusal plane is present in Class I occlusal relationship adults. </p><p> <strong>Study Design</strong></p><p>  Pretreatment lateral cephalometric radiographs from 30 orthodontically untreated Caucasian Class I malocclusion adults were obtained. The occlusal, mandibular, and maxillary planes were traced and compared with the ideal occlusal, mandibular, and maxillary planes according to Delaire.</p><p> <strong> Results</strong> The average occlusal plane was 3.5° below the ideal plane. This divergence was more pronounced in males, and in patients presenting with a hypodivergent skeletal pattern. The maxillary plane displayed on average less than 0.5° of divergence to the ideal. The average mandibular plane showed a divergence of 3.3° below the ideal. </p><p> <strong>Conclusions</strong></p><p> <strong> </strong>When aiming to obtain an ideal orientation of the occlusal plane postoperatively, one must keep in mind that in Class I occlusal relationship adults without any dentofacial disharmony, the occlusal plane is rarely coincident with the ideal plane. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> <a href="http://www.oooojournal.net/article/S2212-4403(13)00058-8/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1649&slc_lang=fa&sid=1 Gregory S.Antorakis 10031947532846007715 10031947532846007715 Yes Department of Orthodontics, Dental School, University of Geneva, Switzerland Stavros Kiliaridis 10031947532846007716 10031947532846007716 No Department of Orthodontics, Dental School, University of Geneva, Switzerland Paolo Scolozzi 10031947532846007717 10031947532846007717 No Department of Oral and Maxillofacial Surgery, University Hospitals of Geneva, Switzerland
