Aim This 3‐year prospective randomized controlled trial compared the clinical, microbiological and biochemical outcome of minimally (Turned, Tur) and moderately rough (TiUnite ® , TiU) implant surfaces in a split‐mouth design. Material and methods The study population included 14 subjects: nine fully edentulous and five partially edentulous subjects with a history of periodontitis. Implants ( n = 78, 39 Tur and 39 TiU) were installed randomly in each patient. Peri‐implant clinical parameters and intra‐oral radiographs were recorded after 3 years of loading. Subgingival plaque and peri‐implant crevicular fluid samples were collected and analysed using culture and quantitative polymerase chain reaction for the biofilm, and enzyme‐linked immunosorbent assay for the concentration of osteoprotegerin and receptor activator of nuclear factor kappa‐B ligand, respectively. Results No statistically significant differences in clinical, microbiological and biochemical parameters could be observed when comparing the Tur and TiU implant surfaces. Conclusion After 3 years of loading, in periodontitis susceptible patients, the moderately rough, TiU implants demonstrated a similar clinical outcome compared with the smoother, turned implants. Longer follow‐up and studies using different implant types are needed to confirm the statement that minimally and moderately rough implant surfaces perform similar, both from a clinical and from a microbiological point of view.
