[Risk factors for dental implant inflammation--a literature review]

Replacing missing teeth with osseointegrated dental implants is a predictable technique as evidanced by overall 5-years survival rate that range between 93% to 97%. Few studies, however have adressed the history and frequency of inflammatory complication associated with dental implant. Inflammatory complications are the main cause of failure of dental implants. In this review we classified the inflammatory complications to acute and chronic and to those limited to the hard tissue, to the soft tissue or both. The incidence of the complications is discussed with an emphasis on their risk factors.
