Mombelli A 2019 Maintenance care is mandatory for the long-term success of periodontal and implant treatment. As it is frequently necessary to treat recurrent or persisting disease, maintenance therapy goes beyond a true prophylaxis. During this lifelong therapy, both the patient and the dental team need to be working closely together. It is imperative to combine efforts to have the build-up of biofilm under control during maintenance and to reduce, as much as possible, the influence that risk factors may play in plaque accumulation as well as in the tissue inflammatory response. Guidelines to evaluate periodontal tissue response are described, and a maintenance protocol is outlined. The management of residual pockets is stressed, and a variety of treatment approaches are considered and evaluated. How to evaluate peri-implant tissues during maintenance is discussed, as is the protocol of the cumulative interceptive supportive therapy. https://sonar.ch/global/documents/23406 eng info:eu-repo/semantics/altIdentifier/doi/10.1111/prd.12255 info:eu-repo/semantics/altIdentifier/pmid/30892766 Periodontology 2000. - 2019 cumulative interceptive supportive therapy implant maintenance long-term results maintenance guidelines mechanical instrumentation patient role periodontal maintenance risk factors supportive therapy Dental Implants Dental Plaque Humans Maintenance therapy for teeth and implants. http://purl.org/coar/resource_type/c_6501
