Patient compliance with postoperative appointments and failure to comply with denture\u2010wearing instructions are critical contributing factors. To the best of the authors\u2019 knowledge, no cases of implant dislodgement attributable to a removable prosthesis have been reported in the literature, although some studies have suggested that improper occlusal forces can cause a long\u2010standing implant to develop peri\u2010implantitis and subsequent displacement of an implant into the sinus cavity.<\/jats:p><jats:p><jats:bold>Case Presentation:<\/jats:bold> A 71\u2010year\u2010old female presented 6 months after undergoing transcrestal sinus lift and implant surgery that involved a modified Summers technique using mineralized solvent\u2010dehydrated cancellous bone allograft and placement of six maxillary implants. A displaced dental implant was retrieved from the right maxillary sinus, which had an intact Schneiderian membrane. The patient was asymptomatic and infection free. The displaced implant was accessed and retrieved via a lateral window sinus technique. No clinical signs of sinus infection were evident, and there were no additional complications during the 2\u2010year follow\u2010up period.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> This case report demonstrates a technique for the retrieval of implants that have been dislodged and migrated into the maxillary sinus cavity caused by an ill\u2010fitting denture and improper masticatory forces.<\/jats:p>","DOI":"10.1902\/cap.2016.150086","type":"journal-article","created":{"date-parts":[[2016,4,4]],"date-time":"2016-04-04T07:50:48Z","timestamp":1459756248000},"page":"175-181","source":"Crossref","is-referenced-by-count":3,"title":["Retrieval of Displaced Implant Attributable to an Ill\u2010Fitting Denture From the Maxillary Sinus Six Months After Transcrestal Sinus Floor Augmentation and Implant Placement"],"prefix":"10.1002","volume":"6","author":[{"given":"Nima D.","family":"Sarmast","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Howard H.","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rui","family":"Ma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julio A.","family":"Carrion","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincent J.","family":"Iacono","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,11]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"853","article-title":"The bone\u2010added osteotome sinus floor elevation technique: Multicenter retrospective report of consecutively treated patients","volume":"14","author":"Rosen PS","year":"1999","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/ID.0000000000000408"},{"key":"e_1_2_9_4_1","first-page":"451","article-title":"Maxillary sinus complications related to endosseous implants","volume":"10","author":"Regev E","year":"1995","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_9_5_1","first-page":"291","article-title":"Migration of implants into the maxillary sinus: Two clinical cases","volume":"20","author":"Galindo P","year":"2005","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.12998\/wjcc.v3.i1.65"},{"key":"e_1_2_9_7_1","first-page":"49","article-title":"Which hard tissue augmentation techniques are the most successful in furnishing bony support for implant placement?","volume":"22","author":"Aghaloo TL","year":"2007","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_9_8_1","first-page":"11","article-title":"Report of the Sinus Consensus Conference of 1996","volume":"13","author":"Jensen OT","year":"1998","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_9_9_1","first-page":"316","article-title":"Implant success in sinus\u2010lifted maxillae and native bone: A 3\u2010year clinical and computerized tomographic follow\u2010up","volume":"24","author":"Sbordone L","year":"2009","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2010.100177"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1902\/annals.2000.5.1.152"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2008.01661.x"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.5005\/jp-journals-10024-1336"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.11607\/jomi.2793"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2008.070067"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1968.00760060632016"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1985.00800120037003"}],"container-title":["Clinical Advances in Periodontics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/cap.2016.150086","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,9]],"date-time":"2025-10-09T20:32:04Z","timestamp":1760041924000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/cap.2016.150086"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,11]]},"references-count":16,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2016,11]]}},"alternative-id":["10.1902\/cap.2016.150086"],"URL":"https:\/\/doi.org\/10.1902\/cap.2016.150086","archive":["Portico"],"relation":{},"ISSN":["2573-8046","2163-0097"],"issn-type":[{"type":"print","value":"2573-8046"},{"type":"electronic","value":"2163-0097"}],"subject":[],"published":{"date-parts":[[2016,11]]}}}
