Dental implants are now an important part of the dental treatment planning process. Many studies have demonstrated the long-term success of dental implants in replacing teeth lost to the caries process or periodontal disease. A significant number of published articles detail the success of implants placed under various conditions, including those placed in bone-augmented sites. Implant failure has long been understood as the complete loss of the dental implant, but it is becoming apparent that an increasing number of implants are associated with inflammatory processes such as perimucositis or periimplantitis and these processes may be more prevalent than previously thought. Published reports indicate that periimplantitis affects approximately 10% of implants and 20% of patients. However, the incidence is higher in some reports, depending on the thresholds used to define the condition. Despite the variability in definitions and the wide array of designs of the studies assessing the success or failure of implants, it is reasonable to assume that we will continue to see an increase in the prevalence of the inflammatory processes that have a negative effect on implants and that may lead to destruction of connective tissue or bone.

This intermediate-level course reviews the microbiology of periimplantitis, perimucositis, and periodontitis. It also explains both the systemic and environmental risks associated with implant failure including smoking, diabetes, osteoporosis, hormonal disturbances, the use of bisphosphonates and the role of genetics. The impact of combinations of risk factors is also discussed. Armed with this knowledge, all dental professionals including dentists, dental hygienists, and dental assistants, will be better prepared to help their patients avoid implant failure.
