Application of Laser in Treatment of Periimplantitis: Review of the Literature

Background and Objectives: Several methods have been introduced for management of periimplantitis. Adjunctive therapies like antibiotics, antiseptics and laser treatments have been proposed in order to improve the non-surgical or surgical treatment options of peri-implantitis. Since lasers have a good capability in ablation of microorganisms and have potent bactericidal and detoxification effects, it has been suggested as one of the best techniques in treatment of periimplantitis. The aim of this study was to review the relevant articles, concerning the application of lasers in treatment of peri-implantitis. Method and Material: PubMed, GoogleScholar, ScienceDirect, InterScience, and IranMedex were searched electronically. Results: The search yielded 44 possibly relevant titles and abstracts. Full texts of 34 English and Persian articles were in access. The results of this article indicated that: (1) In an energy dependent manner, the C02 laser, the diode laser and the Er:YAG laser may be suitable for the irradiation of implant surfaces. (2) By suppressing LPS activity, low-energy Nd:YAG laser might represent an innovative therapy for periimplantitis. (3) The predominant role of lasers in treatment of peri-implantitis is their bactericidal effects. (4) In non-surgical therapy of contaminated implant surfaces Er:YAG high level lasers have shown limited clinical efficacy. (5) According to the results of animal studies lasers act successfully in the surgical management of peri-implantitis, with regard to re-osseointegration. (6) Photodynamic therapy is a promising method in treatment of peri-implantititis. (7) Laser parameters are determinant factors in effectiveness and safety of treatment. (8) Zirconium implants may react quite differently to lasers. Conclusion: Lasers are utilized as an adjunct in the treatment of periimplantitis. The predominant role of lasers in treatment of peri-implantitis is their bactericidal effects without concomitant titanium surface alterations.
