Objectives: To assess the microbiota at implants diagnosed with peri‐implantitis, implant mucositis, or being clinically healthy. Material and methods: Clinical and microbiological data were collected from 213 subjects (mean age: 65.7±14) with 976 implants in function (mean: 10.8 years, SD±1.5). Forty species were identified by the checkerboard DNA–DNA hybridization method. Results: Implant mean % plaque score was 41.8±32.4%. Periodontitis defined by bone loss was found in 44.9% of subjects. Implant mucositis was diagnosed in 59% and peri‐implantitis in 14.9% of all cases. Neisseria mucosa, Fusobacterium nucleatum sp. nucleatum , F. nucleatum sp. polymorphum , and Capnocytophaga sputigena dominated the implant sub‐mucosal microbiota and the sub‐gingival microbiota at tooth sites. Implant probing pocket depth at the implant site with the deepest probing depth was correlated with levels of Eikenella corrodens ( r =0.16, P <0.05), the levels of F. nucleatum sp. vincentii ( r =0.15, P <0.05), Porphyromonas gingivalis ( r =0.14, P <0.05), and Micromonas micros ( r =0.17, P =0.01). E. corrodens was found in higher levels at implants with mucositis compared with implant health ( P <0.05). Subjects who lost teeth due to periodontitis had higher yields of F. nucleatum sp. vincentii ( P <0.02) and N. mucosa ( P <0.05). Independent of implant status subjects with teeth had higher levels of P. gingivalis ( P <0.05), and Leptotrichia buccalis ( P <0.05). Conclusions: At implant sites studied, few bacteria differed by whether subjects were dentate or not or by implant status.
