Study Arms:
- Test: Triclosan toothpaste (Type: EXPERIMENTAL): To brush twice a day with a toothpaste containing 0.3% triclosan and 1450 ppm sodium fluoride in a regular maintenance program for 24 months.~Two months earlier, subjects received Surgical anti-infective therapy for implants with peri-implantitis, periodontal treatment and oral hygiene instruction.
- Control: Fluoride toothpaste (Type: PLACEBO_COMPARATOR): To brush twice a day with a toothpaste containing 1450 ppm sodium monofluorphosphate in a regular maintenance program for 24 months.~Two months earlier, subjects received Surgical anti-infective therapy for implants with peri-implantitis, periodontal treatment and oral hygiene instruction.

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