Peri-implantitis is a plaque-mediated inflammatory condition featured by progressive bone loss. This entity jeopardizes the longevity of dental implants, thus impacting negatively on the quality of life of patients. Moreover, peri-implantitis is suggested to lead to an increased systemic status of inflammation. This may rise the susceptibility to experience life-threating conditions. Therefore, peri-implant infections must be promptly diagnosed and eliminated.

Aiming at resolving the inflammation, several options are advised to remove the infection. Accordingly, implant removal or therapeutic manoeuvres to stablish a healthy ecosystem in the peri-implant environment have been suggested. While the former proved being more predictable, the later demonstrated being more conservative. Indeed, implant removal is commonly associated with regenerative procedures of the alveolar bone deformity that often demand time and is more costly. Anyways, disease severity, implant expendability for biomechanical reasons or esthetic demand seem to be few of the leading aspects in the decision-making process on maintaining or extracting implant showing peri-implant lesions.

Supportive maintenance care (SPT) was shown to be key in preventing disease recurrence. Nonetheless, the compliance of these patients is often erratic. In fact, it is yet unknown the rate of compliance after therapy. Therefore, the goal of this study is to assess the rate and confounders for compliance.
