Implants were placed in the posterior maxilla in combination with a sinus elevation procedure (27 patients) or 6 months after sinus elevation (2 patients). Marginal bone level changes were radiographically evaluated at baseline and 1, 7, and 12 years post\u2010loading. Probing depth was measured; presence\/absence of plaque and bleeding on probing were recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Four out of 59 implants failed in 4 out of 29 patients (cumulative survival rate\u2009=\u200993.2%). The mean bone loss was 0.78\u2009mm (\u00b1\u20090.88) after 12 years. Changes in the mean bone level were statistically significant between baseline and all the other follow\u2010up intervals (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). Statistically significant differences could be demonstrated for the first\u2010 to 12th\u2010year interval (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05) and for the seventh\u2010 to 12th\u2010year interval (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). No statistically significant differences could be demonstrated at the first\u2010 to seventh\u2010year interval (<jats:italic>p<\/jats:italic>\u2009=\u2009.32). The mean overall probing depth was 2.9\u2009\u00b1\u20090.66\u2009mm. Probing depth was moderately correlated with the marginal bone changes at 7 year and after 12 year follow up (<jats:italic>p<\/jats:italic>\u2009=\u2009.05). No signs of peri\u2010implantitis were reported during the 12\u2010year follow\u2010up period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This follow\u2010up demonstrates a very good prognosis when implants with machined surfaces are used. The frequencies of implant failures were very small. Within the limits of the results from this study, the risk of peri\u2010implantitis in the posterior maxilla might be considered a minor problem when implants with machined surfaces are used.<\/jats:p><\/jats:sec>","DOI":"10.1111\/cid.12236","type":"journal-article","created":{"date-parts":[[2014,6,6]],"date-time":"2014-06-06T14:40:51Z","timestamp":1402065651000},"source":"Crossref","is-referenced-by-count":14,"title":["Twelve\u2010Year Retrospective Follow\u2010Up of Machined Implants in the Posterior Maxilla: Radiographic and Peri\u2010Implant Outcome"],"prefix":"10.1111","volume":"17","author":[{"given":"Massimo","family":"Simion","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luca","family":"Gionso","sequence":"additional","affiliation":[{"name":"private practice Milan Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni Battista","family":"Grossi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Briguglio","sequence":"additional","affiliation":[{"name":"private practice Milan Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Filippo","family":"Fontana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,6,6]]},"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.1600-0757.1998.tb00130.x"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.0909-8836..t01-2-.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051X.29.s3.12.x"},{"key":"e_1_2_7_6_1","first-page":"142","article-title":"Early failures in 4,641 consecutively placed Br\u00e5nemark dental implants: a study from stage 1 surgery to the connection of completed prostheses","volume":"6","author":"Friberg B","year":"1991","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1994.050304.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1902\/annals.2003.8.1.328"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8208.2006.00003.x"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1708-8208.2006.00019.x"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1996.070405.x"},{"key":"e_1_2_7_12_1","doi-asserted-by":"crossref","first-page":"207","DOI":"10.1111\/j.1708-8208.2007.00081.x","article-title":"Implant treatment of patients with edentulous jaws: a 20\u2010year follow\u2010up","volume":"10","author":"Astrand P","year":"2008","journal-title":"Clin Implant Dent Relat Res"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2012.02541.x"},{"issue":"4","key":"e_1_2_7_14_1","article-title":"Interventions for replacing missing teeth: different types of dental implants","author":"Esposito M","year":"2007","journal-title":"Cochrane Database Syst Rev"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2004.01117.x"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2004.75.10.1404"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.2001.012003189.x"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2006.00908.x"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2009.090269"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2011.02212.x"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1993.tb00706.x"}],"container-title":["Clinical Implant Dentistry and Related Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fcid.12236","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cid.12236","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T11:42:44Z","timestamp":1716810164000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/cid.12236"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,6,6]]},"references-count":20,"journal-issue":{"issue":"S2","published-print":{"date-parts":[[2015,10]]}},"alternative-id":["10.1111\/cid.12236"],"URL":"https:\/\/doi.org\/10.1111\/cid.12236","archive":["Portico"],"relation":{},"ISSN":["1523-0899","1708-8208"],"issn-type":[{"value":"1523-0899","type":"print"},{"value":"1708-8208","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,6,6]]}}}
