Regenerative Treatment of Peri-Implantitis Following Implant Surface Decontamination With Titanium Brush and Antimicrobial Photodynamic Therapy: A Case Series With Reentry

Figure 1. Clinical view of treatment progression in case 1. (a) Intrasurgical view of the peri-implant defects in positions 30 and 31 at T₀, (b) Intrasurgical view of the residual peri-implant defects at T₁. A supracrestal component is still visible associated with a dehiscence-type defect configuration. Figure 2. Clinical view of treatment progression in case 2. (a) Intrasurgical view of the peri-implant defects in positions 18 and 19 at T₀. (b) Intrasurgical view of the residual peri-implant defects at T₁. A supracrestal component of approximately 1 mm is visible around both implant necks associated with a dehiscence defect extended at the top of the first visible implant thread at the buccal aspect of implant 19. Figure 3. Clinical view of treatment progression in case 3. (a) Intrasurgical view of the peri-implant defect in position 8 at T₀. (b) Intrasurgical view of the regenerated peri-implant defect at T₁.

Figure 4. Clinical view of treatment progression in case 4. (a) Intrasurgical view of the peri-implant defects in positions 2 and 3 at T₀. (b) Intrasurgical view of the regenerated peri-implant defects at T₁. A dehiscence-type defect exposing the machined collar is visible at the buccal aspect of implant 3. Figure 5. Clinical view of treatment progression in case 5. (a) Intrasurgical view of the peri-implant defects in positions 2, 3, and 4 at T₀. (b) Intrasurgical view of the regenerated peri-implant defects at T₁. Figure 6. Clinical view of treatment progression in case 6. (a) Intrasurgical view of the peri-implant defect in position 12 at T₀. (b) Intrasurgical view of the regenerated peri-implant defect at T₁.
