Study Arms:
- Indocyanine green mediated photodynamic therapy (ICG-PDT) (Type: EXPERIMENTAL): Delivery of ICG solution at a concentration of 1 mg/mL will be used. The photosensitizer will be applied until the bottom of the peri-implant pocket using a 1 ml syringe. An 810 nm diode laser (A.R.C. laser GmbH, Nurnberg, Germany) with a power of 200 mW (continuous mode) and total energy of 4 J will be used to excite the ICG by starting from the papilla for 30 s followed by the insertion inside the peri-implant pocket depth for 10 s from both buccal and lingual side moving to coronal direction.
- Peri-implant mechanical debridement (Type: PLACEBO_COMPARATOR): Non-surgical peri-implant mechanical debridement (PIMD) through ultrasonic device with a carbon tip.

Based on this trial design, predict the completion outcome and termination type (if applicable).
