FELDMAN, Bárbara  and  CONTRERAS, Andrés. Erbium:YAG laser in the treatment of peri-implantitis: a literature review. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2017, vol.10, n.1, pp.29-32. ISSN 0719-0107.

A literature review is presented on the effectiveness of the use of the erbium-doped yttrium aluminium garnet (Er:YAG) laser over the past 10 years, with the objective of clarifying its clinical, microbiological, physical, and thermal effects on the implant surface, as well as its effect on the biocompatibility and work time required.

A search was conducted in PubMed database, selecting studies published between 2005 and 2015. A total of 14 in vitro studies were selected, including one animal study, one case report, six case series, two controlled clinical trials, four randomised controlled trials, and five literature reviews.

The literature shows that the use of Er:YAG laser in the treatment of peri-implantitis leads to a clinical improvement, expressed as a decrease in bleeding on probing, a reduction in probing depth, and a clinical attachment gain, that is limited to the first six months after treatment. As regards decontamination of the implant surface, most studies report a decrease in the number of attached bacteria. To avoid physical and thermal damage, the Er:YAG laser must be used at different energy levels, frequency, and exposure times, according to the type of surface of the implant affected. There are still conflicting results as regards the biocompatibility of the surface. Studies agree that treatment with Er:YAG laser leads to less operating time compared to conventional therapies.
