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
