Measurements on the buccal (BI), medial (MI) and lingual (LI) sides of the inter-radicular spaces were taken at 0, 1, 2, 3, 4, 5\u00a0mm from the cemento-enamel junction (CEJ) in an apical direction.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>The male and female BI scores ranged from 2.99\u00b10.73\u00a0mm to 6.18\u00b11.03\u00a0mm and 2.69\u00b10.84\u00a0mm to 6.21\u00b11.22\u00a0mm respectively.

In the maxillary arch, regions between central and lateral incisors, lateral incisor and canine, first and second molars are not viable for mini-screw insertion. The residual inter-radicular regions are proper for implantation at 3\u00a0mm above the CEJ. In the mandible, the regions between incisors and canines are too narrow for mini-screw insertion and the reliable sites for mini-screws are regions between premolars, molars or first molar and second premolar at 2\u00a0mm below the CEJ.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1746-160x-9-13","type":"journal-article","created":{"date-parts":[[2013,4,20]],"date-time":"2013-04-20T08:14:21Z","timestamp":1366445661000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["The anatomical evaluation of the dental arches using cone beam computed tomography - an investigation of the availability of bone for placement of mini-screws"],"prefix":"10.1186","volume":"9","author":[{"given":"Feng","family":"Pan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chung H","family":"Kau","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nada","family":"Souccar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2013,4,20]]},"reference":[{"key":"298_CR1","first-page":"359","volume-title":"Contemporary Orthodontics","author":"WR Proffit","year":"2007","unstructured":"Proffit WR, Fields HW, Sarver DM:Mechanical Principles in Orthodontic Force Control.Contemporary Orthodontics. 2007, Missouri: St. Louis, 359-394. 4,","edition":"4"},{"key":"298_CR2","doi-asserted-by":"publisher","first-page":"1351","DOI":"10.1111\/j.1600-0501.2009.01754.x","volume":"20","author":"M Sch\u00e4tzle","year":"2009","unstructured":"Sch\u00e4tzle M, M\u00e4nnchen R, Zwahlen M, Lang NP: Survival and failure rates of orthodontic temporary anchorage devices: a systematic review.
