Study population: Initially, 80 individuals who underwent the installation of dental implants for making overdentures in the Department of Implant Dentistry, Faculty of Dentistry, University of Santo Amaro, São Paulo, Brazil, in 2007,were evaluated.According to the inclusion and exclusion criteria, the final sample had 64 individuals of both genders, between 40 and 75 years old

Brief summary: The control of biofilm around implants is critical to the success of the implant rehabilitation of edentulous jaw with overdentures, and it is the dentist's duty to inform and guide patients, and keep their maintenance in order to prevent pathological processes that can lead to the implanted component loss.The aim of the present retrospective longitudinal study was to evaluate through clinical periodontal parameters and radiographic images in dental implants rehabilitated with overdentures installed seven years ago. individuals who underwent the installation of dental implants for making full implant-supported upper and lower mucus dentures in the Department of Implant Dentistry, Faculty of Dentistry, University of Santo Amaro, São Paulo, Brazil, in 2007. The periodontal parameters such as probing depth, plaque index, bleeding index and mobility as well as radiographic examination, are key to determine the correct diagnosis in dental implants. The control of biofilm around the implants seems to be a decisive factor for maintaining tissue health. We believe that the maintenance appointments are fundamental, but more studies should be conducted to elucidate microbial and immunological factors in implants placed and due for some time.
