The long-term success of an implant-supported prosthesis is dependent not only on osseointegration of the implant to the surrounding osseous structures, but also the integrity and health of the surrounding peri implant tissues. This paper defines and discusses the dental professional's role in (1) examining and assessing the peri-implant tissues (2) providing clinical maintenance protocols, and (3) recommending effective home-care instructions for a patient with implant-supported prostheses.
