Describe in brief about failing implant
The failing implant may show evidence of pocketing, bleeding upon probing, purulence, and indicates the bone loss patterns are progressing despite previous therapy. Therefore, an implant that is progressively losing its bone anchorage, but is still clinically stable, can be defined as failing.
Failing implants have a poorer prognosis but however, if properly recognized and treated, a failing implant may be saved. Microflora associated with failing dental implants are identical to those found in chronic adult periodontitis. This microflora triggers inflammation and bone loss and is termed peri-implantitis.
