Abstract Aim To investigate whether the lack of keratinized mucosa (KM) affects peri‐implant health after 10 years loading. Materials and Methods Data from 74 patients with 148 implants two randomized controlled studies comparing different implant systems were included analyzed. Clinical parameters including bleeding on probing (BOP), depth (PD), plaque index, marginal bone loss (MBL), KM width (KMW) at buccal sites collected baseline (time final prosthesis insertion), 5‐year postloading. Multivariable logistic linear regression models by means a generalized estimated equation (GEE) used to evaluate influence clinical parameters; BOP, MBL, PD, adjusted for type (one‐piece or two‐piece) compliance. Results A total 35 (24.8%) healthy, 67 (47.5%) had mucositis 39 (27.6%) affected peri‐implantitis. In absence (KM = 0 mm), 75% exhibited mucositis, while in presence (KMW >0 mm) 41.2% mucositis. Regarding peri‐implantitis, corresponding percentages 20% 26.7% mm). Unadjusted showed that tended reduce odds showing BOP (OR: 0.28 [95% CI, 0.07 1.09], p 0.06). The model revealed having 0.21 0.05 0.85], 0.02) using two‐piece 0.34 0.15 0.75], 0.008) significantly reduced BOP. Adjusted GEE associated MBL changes ( < 0.05). Conclusion appears be linked such as but association is weak. design one‐piece may account their increased exhibiting
