Four-Millimeter-Long Posterior-Mandible Implants: 5-Year Outcomes of a Prospective Multicenter Study
Background There is lack of evidence on long‐term success of short dental implants in reduced alveolar bone. Purpose In this prospective 5‐year study, survival and marginal bone loss of 4‐mm implants, which supported fixed dental prostheses (FDPs) in severely resorbed posterior mandibles, were evalu...

There is lack of evidence on long‐term success of short dental implants in reduced alveolar bone.
Purpose
In this prospective 5‐year study, survival and marginal bone loss of 4‐mm implants, which supported fixed dental prostheses (FDPs) in severely resorbed posterior mandibles, were evaluated.
Material and Methods
In 28 patients, evaluation of 86 osseointegrated 4‐mm‐long implants, which supported a 3‐ or a 4‐unit FDP by crown splinting without the use of pontics or cantilevers, was performed over a 5‐year period.
Results
Three subjects dropped out for non‐study reasons: one subject had her three implants removed after 1 year and two subjects died (six implants). Five implants in three subjects were lost between 3 and 5 years. Twenty‐four subjects and 71 implants were active at the 5‐year follow‐up (92.2% survival). After 1 year, significant (p |

In 28 patients, evaluation of 86 osseointegrated 4‐mm‐long implants, which supported a 3‐ or a 4‐unit FDP by crown splinting without the use of pontics or cantilevers, was performed over a 5‐year period.

Three subjects dropped out for non‐study reasons: one subject had her three implants removed after 1 year and two subjects died (six implants). Five implants in three subjects were lost between 3 and 5 years. Twenty‐four subjects and 71 implants were active at the 5‐year follow‐up (92.2% survival). After 1 year, significant (p < .001) mean (standard error of the mean [SEM]) 0.44‐mm (0.05) marginal bone loss occurred. At 2, 3, and 5 years, mean (SEM) bone loss of 0.57 mm (0.06), 0.55 mm (0.07), and 0.53 mm (0.08) occurred, respectively (no significant change after 1 year). At 5 years, average plaque levels were 13.3%; 69% of the implants were plaque free. On average, mucosal bleeding occurred at 8.1% of the implants. During 5 years, two subjects experienced uncomplicated bridge loosening. No other complications occurred during the study.
Conclusion
Four‐millimeter implants can support FDPs in severely resorbed posterior mandibles for 5 years with healthy peri‐implant conditions.</description><identifier>ISSN: 1523-0899</identifier><identifier>ISSN: 1708-8208</identifier><identifier>EISSN: 1708-8208</identifier><identifier>DOI: 10.1111/cid.12252</identifier><identifier>PMID: 25041489</identifier><language>eng</language><publisher>United States: Blackwell Publishing Ltd</publisher><subject>Adult ; Aged ; Aged, 80 and over ; Alveolar Bone Loss - epidemiology ; Alveolar Bone Loss - etiology ; bone atrophy ; bone loss ; bone resorption ; clinical trial ; crown-implant ratio ; Dental Implantation, Endosseous - adverse effects ; Dental Implants ; Dental Restoration Failure ; Dentistry ; Female ; Humans ; Male ; Mandible - surgery ; Middle Aged ; Odontologi ; Prospective Studies ; short implants ; Treatment Outcome</subject><ispartof>Clinical implant dentistry and related research, 2015-10, Vol.17 (S2), p.e385-e395</ispartof><rights>2014 Wiley Periodicals, Inc.</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c4362-562b6f1930b1521dfd7b42dac41754298a24c84e7cc431b392dfd151e884d62e3</citedby><cites>FETCH-LOGICAL-c4362-562b6f1930b1521dfd7b42dac41754298a24c84e7cc431b392dfd151e884d62e3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,780,784,885,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/25041489$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink><backlink>$$Uhttps://gup.ub.gu.se/publication/203672$$DView record from Swedish Publication Index$$Hfree_for_read</backlink></links><search><creatorcontrib>Slotte, Christer</creatorcontrib><creatorcontrib>Grønningsaeter, Arne</creatorcontrib><creatorcontrib>Halmøy, Anne-Marie</creatorcontrib><creatorcontrib>Öhrnell, Lars-Olof</creatorcontrib><creatorcontrib>Mordenfeld, Arne</creatorcontrib><creatorcontrib>Isaksson, Sten</creatorcontrib><creatorcontrib>Johansson, Lars-Åke</creatorcontrib><title>Four-Millimeter-Long Posterior-Mandible Implants: 5-Year Outcomes of a Prospective Multicenter Study</title><title>Clinical implant dentistry and related research</title><addtitle>Clinical Implant Dentistry and Related Research</addtitle><description>Background
