The goal of this clinical trial is to learn whether adjunctive electrolytic surface decontamination can improve the outcomes of surgical treatment of peri-implantitis. The main questions it aims to answer are:

• Does electrolytic surface decontamination reduce probing pocket depth more effectively than conventional surgical treatment alone?
• Does electrolytic surface decontamination improve bleeding on probing, suppuration, and radiographic bone levels?

Researchers will compare conventional surgical treatment plus electrolytic surface decontamination with conventional surgical treatment alone.

Participants will:

• Receive surgical treatment for peri-implantitis
• Be randomly assigned to one of the two treatment groups
• Attend follow-up visits for clinical and radiographic examinations
• Undergo assessment of probing pocket depth, bleeding on probing, suppuration, and bone level changes during follow-up

Inclusion Criteria:

Adults aged 18 years or older Diagnosis of peri-implantitis requiring surgical treatment Presence of at least one dental implant diagnosed with peri-implantitis Ability and willingness to attend follow-up visits Provision of written informed consent

Exclusion Criteria:

Pregnancy or lactation Uncontrolled systemic diseases that may affect healing Immunosuppressive therapy History of head and neck radiotherapy Current use of medications known to affect bone metabolism Inability to comply with the study protocol or follow-up schedule Previous surgical treatment of peri-implantitis at the study implant site
