Prevalence of peri-implant disease in Germany: results of the 6th German Oral Health Study (DMS • 6).

OBJECTIVE: To report the prevalence of peri-implant disease and factors associated with peri-implant tissue inflammation in a German population-based cohort comprising younger adults (35- to 44-year-olds) and younger seniors (65- to 74-year-olds) among participants in the 6th German Oral Health Study (DMS • 6). METHOD AND MATERIALS: Data were available for 925 and 788 younger adults and younger seniors, of whom 63 (n = 108 implants) and 163 (n = 477 implants) had at least one dental implant. Probing depth (PD) and bleeding on probing (BOP) were recorded at six sites per implant. For each implant, peri-implant health was defined as a maximum of one site with BOP. Peri-implant mucositis was defined as at least two sites with BOP with a maximum of one site with BOP having PD > 6 mm. Peri-implantitis was defined as at least two sites with BOP and PD > 6 mm. RESULTS: Among the entire population, 2.1% (95% confidence interval [CI], 1.3-3.5%) of younger adults and 7.0% (95% CI, 5.2-9.4%) of younger seniors were diagnosed with peri-implant disease. Among the study participants with dental implants, healthy peri-implant tissue was observed in 68.3% (95% CI, 56.1-78.7%) of younger adults and 68.1% (95% CI, 60.7-74.9%) of younger seniors. Peri-implant mucositis and peri-implantitis were diagnosed in 30.2% (95% CI, 19.9-42.2%) and 1.6% (95% CI, 0.2-7.2%) and 30.7% (95% CI, 24.0-38.0%) and 1.2% (95% CI, 0.3-3.9%) of younger adults and younger seniors, respectively. At the implant level, the corresponding values were 25.9% (95% CI, 18.4-34.7%) and 0.9% (95% CI, 0.1-4.2%) and 20.5% (95% CI, 17.1-24.3%) and 0.4% (95% CI, 0.1-1.3%), respectively. Stage III/IV periodontitis was significantly associated with an increased risk of peri-implant disease (odds ratio, 2.52; P = .006). CONCLUSION: Peri-implant mucositis was frequently observed in participants with implants, whereas clinically defined (probing based) peri-implantitis was rare in both age groups. Severe periodontitis (stage III/IV) was associated with higher odds of developing peri-implant disease. (Quintessence Int 2026;57(Suppl):S46-S54; doi: 10.3290/j.qi.b6955520).
