The use of dental implants in order to rehabilitate patients with fixed or removable implant-supported restorations has become widespread in recent decades. For example, according to the current German Oral Health Study (DMS V), patients were already 10 times more likely to be treated with implants in 2014 than in 1997. According to statistics from the American Dental Association, an estimated 5 million implants are placed annually in the USA alone. The increasing life expectancy together with the desire for fixed restorations is expected to further strengthen this trend in the future. The steadily increasing number of implants that are placed by dentists has also been accompanied by an increase in the overall number of post-implant complications. Thus, due to the increased prevalence of biological complications, relevant patient-specific risk factors must be accounted for as part of implant planning and treatment. In this sense, a synoptic treatment concept that considers the foreseeable patient-specific risk factors for peri-implant inflammation plays an important role from the pre-implant to the post-prosthetic treatment phase. The article explores the multitude of patient-specific risk factors and the various therapeutic options available as the key to long-term implant treatment success.
