Background. The primary aim of this systematic literature is to answer the following focused question: Is laser therapy, as a monotherapy or as an adjunctive therapy, an efficacious treatment modality for patients with peri-implantitis? Methods. The PubMed database and Google scholar and also research gate are the sources of articles that used in this literature. Results. This literature shows that the CO2 laser is reported to be safe and able to enhance bone regeneration. The diode laser (980 nm) seems to be effective in its bactericidal effect without changing the implant surface pattern. The Er, Cr: YSGG laser was reported to obtain bone regeneration around a failing implant in one case, while the Er: YAG laser exhibits a strong bactericidal effect against periodontopathic bacteria at a low energy level. Non-surgical laser treatment with a single application of either an erbium: yttrium-aluminum-garnet (Er: YAG) (2, 940-nm) laser or a diode (660-nm) laser in combination with a phenothiazine chloride dye is efficient in controlling inflammation around treated implants for at least 6 months following intervention, whereas it has only a mild effect on reduction in probing depth (PD) and gain in clinical attachment level (CAL). Conclusions. Based on the limited information currently available, any superiority of laser treatment in comparison to conventional treatment of peri-implantitis could not be identified. Considering the high heterogeneity and the low number of included studies, the authors cautiously conclude that non-surgical laser therapy may be investigated as phase I therapy for the treatment of peri-implantitis.
