All patients received fixed prostheses. The overall majority of patients had each five implants placed. Radiographs were obtained at prosthesis delivery, at the 1 and 5\u2010year follow\u2010up.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 1,230 implants in 259 patients (67%) were possible to follow up for 5 years. Implant C<\/jats:styled-content>umulative S<\/jats:styled-content>urvival R<\/jats:styled-content>ates (CSR<\/jats:styled-content>) in 5 years for G<\/jats:styled-content>roups 1\u20134 were 99.7, 97.0, 98.5, and 98.6%. The corresponding prosthesis treatment CSR<\/jats:styled-content> was 100, 99.3, 98.5, and 98.6%, respectively. Significantly, more patients (p<\/jats:italic>\u2009<\u2009.05) lost turned implants after one\u2010stage surgery (G<\/jats:styled-content>roup 2). Frequency distributions of implants revealed that >1.2\u2009mm bone loss was observed around 75 implants (6.4%). The moderately rough central (midline) implant showed more bone loss than other placed implants (G<\/jats:styled-content>roup 3; p<\/jats:italic>\u2009<\u2009.05). The youngest half of included patients at surgery (Y<\/jats:styled-content>oungest50%<\/jats:sup>; n<\/jats:italic>\u2009=\u2009193) presented significantly higher mortality than older patients as well as compared to normal population (p<\/jats:italic>\u2009<\u2009.05). Patients in the Younger50%<\/jats:sup> group showed also an association to patients with complete loss of all implants and patients with most implants with obvious bone loss after 5 years.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>All four treatment procedures served well during the 5 years of follow\u2010up and only eight patients (2.1%) were complete failures or showed obvious bone loss (>1.8\u2009mm) at several implants (>2 implants), mostly observed in younger patients. The few complications in relation to implant failure and\/or obvious bone loss could be associated to both local impact<\/jats:italic> factors (surface, implant site, surgical protocol) as well as to host response<\/jats:italic> factors (systemic health).<\/jats:p><\/jats:sec>","DOI":"10.1111\/cid.12116","type":"journal-article","created":{"date-parts":[[2013,7,24]],"date-time":"2013-07-24T18:47:48Z","timestamp":1374691668000},"page":"413-424","source":"Crossref","is-referenced-by-count":38,"title":["Rehabilitation of Edentulous Mandibles by Means of Osseointegrated Implants: A 5\u2010Year Follow\u2010Up Study on One or Two\u2010Stage Surgery, Number of Implants, Implant Surfaces, and Age at Surgery"],"prefix":"10.1111","volume":"17","author":[{"given":"Bertil","family":"Friberg","sequence":"first","affiliation":[{"name":"The Br\u00e5nemark Clinic Public Dental Health Service G\u00f6teborg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Torsten","family":"Jemt","sequence":"additional","affiliation":[{"name":"The Br\u00e5nemark Clinic Public Dental Health Service G\u00f6teborg Sweden"},{"name":"Department Prosthetic Dentistry\/Dental Material Science Sahlgrenska Akademin University of G\u00f6teborg G\u00f6teborg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,7,24]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bdj.4809551"},{"key":"e_1_2_7_3_1","first-page":"515","article-title":"Sentiments expressed in relation to tooth loss: a qualitative study among edentulous Saudis","volume":"16","author":"Omar R","year":"2003","journal-title":"Int J Prosthodont"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016350701739519"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyh375"},{"key":"e_1_2_7_6_1","first-page":"7","volume-title":"Osseointegrated implants in the treatment of the edentulous jaw.
