Abstract
Introduction: Despite the long-term predictability of Osseointegrated implants, biologic, biomechanical and esthetic complication can occur in a small percentage of cases. With increasing use of dental implants for rehabilitation of missing teeth there is increase in cases of peri-implantitis. Use of photodynamic therapy has showed promising results for management of peri-implantitis. Materials and methods: Sixteen patients of peri-implantitis were selected and randomly assigned to test or control group. Readings were taken at baseline, 6 weeks, 6 months, and 24 months for Probing Pocket Depth (PPD), and Bleeding on Probing (BOP). Control group patients were treated with periodontal therapy whereas test group patients were given photodynamic therapy additionally. Result: 64% reduction in PPD was observed in test group whereas BOP and suppuration were absent. Significant reduction in PPD was seen in control group as well. After 24 months test group had average pocket depth of 2 mm and control group 3 mm. Conclusion: Use of photodynamic therapy added therapeutic benefit to conventional management and should be considered as a part of peri-implantitis management therapy.
