Surgical Treatment of Peri-implantitis with Photodynamic Therapy and Guided Bone Regeneration

Peri-implantitis is diagnosed around implants in the area of 31-41 and also 13. The sites are surgically exposed, granulation tissue removed and implant surface decontaminated. A mild form of implantoplasty is also conducted with a mechanical rotating titanium brush. Photodynamic therapy (PAD - Photo Activated Oral Disinfection - Tolonium Chloride Dilute red light 635 nm) is applied for additional disinfection of the implant surface. The defects are regenerated with Xenograft and membrane (Bio Oss and B
