Implant maintenance for the prevention of biological complications: Are you ready for the next challenge?

With increasing knowledge of wound biology and material sciences, the provision of dental implants as a treatment modality has become increasingly predictable and more commonly used to replace missing teeth. However, without appropriate follow up, peri-implant diseases could develop and affect the long-term success of implants. Currently, there is not enough focus on the prevention of peri-implant diseases, as compared to the definition of the disease, its prevalence, and treatment. In the present study, we aim to summarize various factors influencing the successful maintenance of dental implants and highlight current gaps in knowledge. Factors influencing the successful maintenance of dental implants can be divided into three categories: implant-, dentist-, and patient-related factors. Patients with dental implants are often more dentally aware, and this offers an advantage. Compared to gingiva, peri-implant mucosa responds at a different pace to the bacterial challenge. Dental practitioners should be aware of how treatment protocols affect long-term success, and be vigilant in detecting peri-implant diseases at an early stage. Compared to periodontal maintenance, less longitudinal studies on implant maintenance are available, and therefore, there is a tendency to rely heavily on information extrapolated from the periodontal literature. More studies on the significance of implant maintenance care are required.
