Complications for the implants, MRFCDs, and CRDPs were recorded in four different recall periods: 0\u20135\u00a0years, 5\u201310\u00a0years, 10\u201315\u00a0years, and more than 15\u00a0years. The survival and failure times based on Kaplan\u2013Meier statistics were analyzed using Lifetest procedures. Product\u2010limit survival estimates were used for cumulative survival rates (CSRs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean service time was 18.5\u00a0years. The CSR for the implants and MRFCDs was 91.8% at 16.9\u00a0years (confidence intervals: 85.2% and 95.5%) and 80% at 19.6\u00a0years (confidence intervals: 44.1% and 94.1%), respectively. The implant failures after 15\u00a0years occurred because of a tumor resection. Acrylic resin tooth fracture (45.8% of patients) and wear (75% of patients) were the most common complications with the MRFCD. Retaining screw complications [loosening (8.1% of retaining screws) and fracture (11.3% of retaining screws)] were also common.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The outcomes seen with MRFCD over the long term were favorable. After placement of prostheses, 1 implant loss was observed potentially due to prosthetic\/hygiene\/periodontal factors. However, potential maintenance complications such as acrylic resin tooth fracture and\/or wear and retaining screw loosening and fracture may occur in the long term when a similar design is used for the mandible.<\/jats:p><\/jats:sec>","DOI":"10.1111\/clr.13488","type":"journal-article","created":{"date-parts":[[2019,5,27]],"date-time":"2019-05-27T12:03:04Z","timestamp":1558958584000},"page":"817-825","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Treatment of edentulous mandible with metal\u2010resin fixed complete dentures: A 15\u2010 to 20\u2010year retrospective study"],"prefix":"10.1111","volume":"30","author":[{"given":"Edwin A.","family":"McGlumphy","sequence":"first","affiliation":[{"name":"Division of Restorative and Prosthetic Dentistry The Ohio State University, College of Dentistry Columbus Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shervin","family":"Hashemzadeh","sequence":"additional","affiliation":[{"name":"Division of Restorative and Prosthetic Dentistry The Ohio State University, College of Dentistry Columbus Ohio"},{"name":"Graduate Prosthodontics Program, Department of Restorative Dentistry University of Washington Seattle Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7101-363X","authenticated-orcid":false,"given":"Burak","family":"Yilmaz","sequence":"additional","affiliation":[{"name":"Division of Restorative and Prosthetic Dentistry The Ohio State University, College of Dentistry Columbus Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bradley A.","family":"Purcell","sequence":"additional","affiliation":[{"name":"Private Practice Columbus Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Leach","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Surgery The Ohio State University College of Dentistry Columbus Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter E.","family":"Larsen","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Surgery The Ohio State University College of Dentistry Columbus Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,6,12]]},"reference":[{"key":"e_1_2_7_2_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 up","volume":"10","author":"Astrand P.","year":"2008","journal-title":"Clinical Implant Dentistry and Related Research"},{"key":"e_1_2_7_3_1","first-page":"417","article-title":"Long\u2010term treatment outcomes in edentulous patients with implant\u2010fixed prostheses: The Toronto study","volume":"17","author":"Attard N.
