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.
