The purpose of this study was to evaluate the effects of Er:YAG laser on degranulation and implant surface debridement in peri-implant infection. The peri-implant infection was experimentally induced in dogs, and the treatment was performed using an Er:YAG laser or a plastic curet. Animals were sacrificed after 24 weeks, and undecalcified histological sections were prepared and analyzed. Degranulation and implant surface debridement were obtained effectively and safely by Er:YAG laser. Histologically, a favorable formation of new bone was observed on the laser-treated implant surface, and the laser group showed a tendency to produce greater bone-to-implant contact than the curet group. These results indicate that the Er:YAG laser therapy has promise in the treatment of peri-implantitis.
本研究的目的是评估铒激光对种植体周围感染中脱颗粒和种植体表面清创的影响。在犬身上通过实验诱导种植体周围感染，并使用铒激光或塑料刮治器进行治疗。24周后处死动物，制备并分析未脱钙组织切片。铒激光能有效且安全地实现脱颗粒和种植体表面清创。组织学上，在激光处理过的种植体表面观察到新骨形成良好，且激光组比刮治器组有产生更大骨-种植体接触的趋势。这些结果表明铒激光治疗在种植体周炎的治疗中有应用前景。
