Peri-implantitis lesion can be diagnosed early on the radiograph by detecting bone loss around the implant.Implant mobility indicates the final stage of peri-implant disease. It is evident that peri-implant disease should be recognized earlier, to allow intervention before a substantial portion of the supporting bone is lost.Therefore, diagnostic procedures used around implants, should include sensitive parameters to detect early signs and symptoms of inflammation.the microbiota associated with failing dental implants is similar to the flora commonly associated with periodontally involved teeth, and the main cause of periimplantitis is dental plaque. Acceptable techniques for the diagnosis of peri-implantitis and its associated bone loss remain clinical probing and parallel technique radiographs. Clinical probing is accurate only if the prosthetic superstructure is removed, whereas retention of the superstructure may aid in placement of radiographic positioning devices. Clinical mobility is a late diagnostic finding of low sensitivity.For satisfactory long term results, the underlying etiology, as in all therapy, must be identified and corrected.
