The case presented here illustrates the clinical application of this treatment approach as part of a full mouth rehabilitation. A 64\u2010year\u2010old male presented with poor esthetics and function due to multiple missing teeth in both arches and nonrestorable maxillary teeth and mandibular molars. Although the mandibular arch could be restored with a combination of fixed crowns and a removable partial denture, the remaining maxillary teeth were all deemed to have a poor prognosis. In shared decision making, the patient opted for removal of these maxillary teeth and replacement with an implant\u2010supported bar overdenture. Following minimally traumatic extraction and partial grafting of sockets using a xenogeneic bone substitute, four bone\u2010level implants were placed immediately in the canine\u2013premolar positions (13, 15, 23, and 25) according to a prosthetically driven three\u2010dimensional plan, achieving insertion torques of 40\u201345\u2009Ncm. After a 5\u2010month uneventful osseointegration period and minimally invasive uncovering surgery, straight multiunit abutments and an Ackermann\u2010type bar (a prosthetic bar design unrelated to the Eckermann implant system) were used to support a bar\u2010retained maxillary overdenture with bilateral balanced occlusion. At the 4\u2010 and 7\u2010month follow\u2010up visits, peri\u2010implant tissues were healthy, the implants and bar remained stable, and no biological complications were detected. The patient reported improved comfort, chewing ability, and esthetics. These findings illustrate the short\u2010term clinical feasibility of this treatment approach in this individual patient.<\/jats:p>","DOI":"10.1155\/crid\/5908049","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T09:32:32Z","timestamp":1788773552000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Maxillary Bar Overdenture on Immediately Placed Implants: A Clinical Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-9822-5194","authenticated-orcid":false,"given":"Rub\u00e9n Jim\u00e9nez","family":"Hern\u00e1ndez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,7]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2009.01493.x"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0022-3913(00)70037-0"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/clr.70084"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/clr.70063"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD003878.pub4"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2009.01820.x"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1556\/IMAS.5.2013.4.3"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.12625"},{"key":"e_1_2_12_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.13726"},{"key":"e_1_2_12_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/clr.70069"},{"key":"e_1_2_12_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpor.2018.08.006"},{"key":"e_1_2_12_12_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12903-021-01572-6"},{"key":"e_1_2_12_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/clr.14109"},{"key":"e_1_2_12_14_2","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.13290"},{"key":"e_1_2_12_15_2","doi-asserted-by":"publisher","DOI":"10.1097\/ID.0b013e3181676059"},{"key":"e_1_2_12_16_2","doi-asserted-by":"publisher","DOI":"10.4103\/jips.jips_409_19"}],"container-title":["Case Reports in Dentistry"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crid\/5908049","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crid\/5908049","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crid\/5908049","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T09:32:33Z","timestamp":1788773553000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crid\/5908049"}},"subtitle":[],"editor":[{"given":"Hannah","family":"Wesley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":16,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1155\/crid\/5908049"],"URL":"https:\/\/doi.org\/10.1155\/crid\/5908049","archive":["Portico"],"relation":{},"ISSN":["2090-6447","2090-6455"],"issn-type":[{"value":"2090-6447","type":"print"},{"value":"2090-6455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2026-02-14","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-08-31","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-09-07","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"5908049"}}
