Malnutrition of the graft may also ensue. This radiographical study uses cone beam computerized tomography to identify the superior alveolar canal, to measure its diameter and its distance from the sinus floor at precise tooth positions to provide the implant surgeon with information about the position and the diameter of the canal.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>One hundred and fifty\u2010six patients (156) scanned with a <jats:styled-content style=\"fixed-case\">N<\/jats:styled-content>ewtom <jats:styled-content style=\"fixed-case\">VG<\/jats:styled-content> device were included in this study.

The large variation on the distance of the canal from the sinus floor dictates an individual evaluation of its position and not the use of mean values. Great care must be exercised by the radiologist to reliably identify the canal.<\/jats:p><\/jats:sec>","DOI":"10.1111\/clr.12119","type":"journal-article","created":{"date-parts":[[2013,2,19]],"date-time":"2013-02-19T03:42:00Z","timestamp":1361245320000},"page":"553-559","source":"Crossref","is-referenced-by-count":39,"title":["Radiographic evaluation of the superior alveolar canal: measurements of its diameter and of its position in relation to the maxillary sinus floor: a cone beam computerized tomography study"],"prefix":"10.1111","volume":"25","author":[{"given":"Dimitrios","family":"Apostolakis","sequence":"first","affiliation":[{"name":"Maxillofacial Radiology and Diagnosis Chania Crete Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arlana K.","family":"Bissoon","sequence":"additional","affiliation":[{"name":"Faculty of Medical Sciences School of Dentistry The University of the West Indies St. Augustine Trinidad and Tobago"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,2,18]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1259\/dmfr.25.1.9084281"},{"key":"e_1_2_5_3_1","first-page":"199","article-title":"Maxillary sinus: anatomy, physiology, surgery, and bone grafting related to implantology\u2013eleven years of surgical experience (1979\u20131990)","volume":"16","author":"Chanavaz M.","year":"1990","journal-title":"Journal of Oral Implantology"},{"key":"e_1_2_5_4_1","first-page":"119","article-title":"Sinus grafting related to implantology.
