Regardless of the type of implant, the loss of the implant crestal bone in the first year during post-implanttreatment and after functioning by prosthetic treatment is often greater than that of the following year. Possible causes for early implant bone loss include surgical trauma, occlusal overload, peri-implantitis, microgap, bio-logical width, and crest modules of the implant itself. Plaque index and Gingival index values were also found significantly higher for implants without KM(keratinized mucosa). KM of at least 2 mm should be maintained. Contour of implant restoration is known as one of the risk indicators of peri-implantitis. Prevalence of peri-implantitis was significantly greater in the bone-level group when the emergence angle was >30 degrees compared to an angle ≤30 degrees. Emergence angle of >30 degrees is a signific ianndti craistokr for peri-implantitis and convex profile creates an additional risk for bone-level implants, but not fo rtissuelevel implants. Biocom-patible materials should be used for all implant prosthetics, especially f otrhmeation of high polished surfaces with a reasonable appearance on the transmucosal part of the imp rlaensttorations. Bacterial products of the biofilm provoke an immune response in the gingival tissues. As btihoefilm maturesmore complex inter-reactions occur and bacteria with more virulent qualities apprpoevaork,ing a more complex immune system response. Inflammation and immune response cannot be resolved until the bacteria biofilm is removed. To minimize the incidence of complications, dental professionals should make great effort in choosing reliable components and materials for implant- supported FDPs and the patients should be placed in well-structured maintenance system after treatment.
