Implants were categorized based on the pre\u2010extraction site history: Mobility Class (M2), Mobility Class (M3), Furcation Grade (G3), Furcation Grade (G4), and a control group. A 1:4 propensity score matching (PSM) was performed to balance baseline covariates (age, sex, smoking, diabetes, implant arch).<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n After PSM, a balanced cohort of 3925 implants (785 risk implants, 3140 control implants) was analyzed. The 10\u2010year survival probability for the matched control group was 98.9%. All risk groups demonstrated significantly lower survival, with M2 at 94.6% and G4 at 95.5%. The adjusted multilevel Cox model confirmed a significantly higher risk of failure for all exposure groups. The adjusted hazard ratio was 2.3 for M2 (95% CI: 1.2\u20134.4), 3.8 for M3 (95% CI: 1.9\u20137.5), 3.0 for G3 (95% CI: 1.4\u20136.5), and 4.5 for G4 (95% CI: 2.1\u20139.8), compared to the matched controls (all\n p<\/jats:italic>\n \u2009<\u20090.01).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n A pre\u2010extraction history of severe tooth mobility or advanced furcation involvement at an implant site is significantly associated with long\u2010term implant failure. Rather than being independent biological causes, these clinical signs likely serve as historical markers for severe localized bone loss and heightened periodontitis susceptibility and should be carefully considered during risk assessment and treatment planning.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/clr.70127","type":"journal-article","created":{"date-parts":[[2026,4,4]],"date-time":"2026-04-04T05:39:20Z","timestamp":1775281160000},"page":"835-840","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prior Tooth Mobility and Furcation Involvement Are Associated With Higher Dental Implant Failure Rates: A Propensity\u2010Matched Cohort Study"],"prefix":"10.1111","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6951-8794","authenticated-orcid":false,"given":"Georgios S.","family":"Chatzopoulos","sequence":"first","affiliation":[{"name":"Division of Periodontology, School of Dentistry University of Minnesota Minnesota USA"},{"name":"Faculty of Dentistry, Health Sciences Aristotle University of Thessaloniki Thessaloniki Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Larry F.","family":"Wolff","sequence":"additional","affiliation":[{"name":"Division of Periodontology, School of Dentistry University of Minnesota Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,3]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/jre.13351"},{"issue":"8","key":"e_1_2_12_3_1","first-page":"1083","article-title":"Effectiveness of Implant\u2010Supported Fixed Partial Denture in Patients With History of Periodontitis: A Systematic Review and Meta\u2010Analysis","volume":"48","author":"Carra M.
