Peri-Implantitis Management: Surgical versus Non-Surgical Approach Using Photodynamic Therapy Combined with Hydrogen Peroxide (OHLLT—Oxygen High Level Laser Therapy): A Retrospective Controlled Study

Peri-implantitis management could be performed either with a surgical or non-surgical approach to the implant surfaces. Various treatment options have been proposed in literature, such as antiseptic and antibiotic therapies, chemical agents, curettes, ultrasonic, air abrasive, rotary titanium brushes laser treatments; particular, photodynamic therapy combined hydrogen peroxide (OHLLT) has proved efficient removal of bacterial biofilm from The aim our study is compare OHLLT approach. We selected cluster 227 implants affected by peri-implantitis: 139 were treated 88 Bone loss pre-operative post-operative (with follow-up five years) registered. collected data entered on Statistical Package for Social Sciences (SPSS) version 11.5. results indicate statistically significant difference between two groups, mean bone after 2.3 mm 3.8 approach; according Kolmogorov–Smirnov test, overall followed normal distribution (value test statistic = 0.0891; p 0.35794). Thus, case peri-implantitis seems more effective, probably due possibility deeper sanitization surfaces, hardly reachable only
