Both groups were treated with a minimal mucoperiosteal flap elevation approach. After a 12\u2010week healing period, the animals were sacrificed, and samples were obtained.

However, less resorption of the lingual and buccal crest may be expected when implants are placed 2\u00a0mm subcrestally, but this is not related to implant design. Moreover, implants placed subcrestally produced better bone\u2010to\u2010implant contact measurements.<\/jats:p><\/jats:sec>","DOI":"10.1111\/clr.12267","type":"journal-article","created":{"date-parts":[[2013,10,12]],"date-time":"2013-10-12T01:33:46Z","timestamp":1381541626000},"page":"1286-1294","source":"Crossref","is-referenced-by-count":15,"title":["Crestal bone loss related to immediate implants in crestal and subcrestal position: a pilot study in dogs"],"prefix":"10.1111","volume":"25","author":[{"given":"Jose Luis","family":"Calvo\u2010Guirado","sequence":"first","affiliation":[{"name":"Department of General and Implant Dentistry Faculty of Medicine and Dentistry University of Murcia Murcia Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia Jara","family":"L\u00f3pez\u2010L\u00f3pez","sequence":"additional","affiliation":[{"name":"Department of General and Implant Dentistry Faculty of Medicine and Dentistry University of Murcia Murcia Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose Eduardo","family":"Mate Sanchez","sequence":"additional","affiliation":[{"name":"Department of General and Implant Dentistry Faculty of Medicine and Dentistry University of Murcia Murcia Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jordi","family":"Gargallo Albiol","sequence":"additional","affiliation":[{"name":"Department of Implant Dentistry International University of Catalonia Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eugenio","family":"Velasco Ortega","sequence":"additional","affiliation":[{"name":"Department Of General Dentistry Faculty of Dentistry University of Seville Seville Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafael","family":"Delgado Ruiz","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics and Digital Technologies Stony Brook University New York NY USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,9,30]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0300-9785(81)80077-4"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2005.00642.x"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2005.00726.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2006.01315.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2009.01860.x"},{"key":"e_1_2_7_7_1","first-page":"45","article-title":"Buccal bone remodeling after immediate implantation with a flap or flapless approach A pilot study in dogs","volume":"1","author":"Barros R.R.M.","year":"2009","journal-title":"Titanium"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2005.00693.x"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2006.01270.x"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/154405910308200316"},{"key":"e_1_2_7_11_1","first-page":"26","volume-title":"ITI Treatment Guide.
