The objective is to review the literature on clinical, radiographic, and biochemical parameters used for monitoring peri-implant conditions. We performed A MEDLINE search that included articles published in English until the end of August 2003 and we selected results from human and experimental animal studies From the literature, we found that he parameters that may be used to assess the presence of peri-implant health and the severity of peri-implant disease include plaque assessment, mucosal conditions, peri-implant probing depth, width of the peri-implant keratinized mucosa, periimplant sulcus fluid analysis, suppuration, implant mobility and discomfort, resonance frequency analysis, and radiographic evaluation. Based on the analysis of the available evidence, it appears reasonable to use a number of clinical and radiographic parameters to discriminate between peri-implant health and disease. We must conclude that systematic and continuous monitoring of peri-implant tissues during maintenance care is recommended for the early diagnosis of peri-implant disease.
