[Research advances in peri-implantitis relevant factors and therapy].

Abstract Peri-implantitis has been defined as an inflammatory process affecting tissues around an osseo-integrated implant in function, and resulting in the loss of supportive alveolar bone. As it was one of the main causes which led to the failure of implant treatment, its risk factors and treatment were attracting more and more attention. This review summarized the progress of clinical research on peri-implantitis risk factors and treatments.
