Electrolytic cleaning is a promising treatment for dental implant decontamination, but this mode of therapy has not yet been clinically tested as an adjunct to the non-surgical treatment of periimplantitis. Electrolytic cleaning is a promising treatment for dental implant decontamination, but this mode of therapy has not yet been clinically tested as an adjunct to the non-surgical treatment of periimplantitis.This is study is a proof of principle study, thus, a case series study is selected to start with. As this is a pilot study to test for the first time the electrolytic cleaning under non-surgical therapy, the sample size has been estimated in a minimum of 25 patients. If the results of this case series study are favourable, a future study with a clinical trial design is then planned to do.~Therapeutic success is defined as as a composite index (Sanz & Chapple 2012 criteria of disease resolution) that includes: (1) probing pocket depth < 5 mm, (2) no bleeding on probing/suppuration and (3) no additional bone loss, at 6 and 12 months). Secondary objectives are: Changes in the clinical outcomes measurements.Changes in the radiological outcomes measurements. Changes in the patient-reported outcomes (PROMs). Evaluation of the outcomes related to the prosthetic restoration.~This study will be carried out in the following centers:~Postgraduate Periodontal Clinic at the Faculty of Odontology-Universidad Complutense of Madrid (Spain)~CEOSA-Madrid Private Dental Centre~After the non-surgical therapy, patients will be recalled for control visits, with supra- gingival removal of biofilm with air polishing without anaesthesia at:~3 months.~6 months.~12 months. After non-surgical therapy, patients will be included in a strict peri-implant maintenance therapy program to avoid re-contamination of the affected implants. Removal of biofilm with air polishing without anaesthesia and oral hygiene instruction reinforcement will be performed at: 3 months, 6 months, 9 months and 12 months.
Electrolytic cleaning is a promising treatment for dental implant decontamination, but this mode of therapy has not yet been clinically tested as an adjunct to the non-surgical treatment of periimplantitis.~A prospective clinical and radiographic case series study will be performed to evaluate the clinical performance of the adjunctive use of electrolytic cleaning as an adjunct to a non-surgical therapy protocol that includes curettage of the peri-implant soft tissue. This is study is a proof of principle study, thus, a case series study is selected to start with. If the results of this case series study are favourable, a future study with a clinical trial design is then planned to do.
