A laser treatment for periimplantitis using two different wavelengths (Er:YAG and Nd:YAG) will be compared to standard treatment in a randomized clinical trial.
The general aim of this study is to evaluate the clinical outcome of the treatment of peri-implantitis using a combination of a Er:YAG and Nd:YAG laser protocol or using a conventional mechanical treatment in patients with a diagnosis of peri-implantitis.

For the laser group we will use a Lightwalker Laser (Fotona) with a Er:YAG 2940 nm and Nd:YAG 1064 nm wavelengths units. The laser protocol will follow the instructions of the manufacturer (TwinLight protocol) and consists of degranulation of necrotic soft tissue and bone, implant surface disinfection and creating spot bleeding in bone with Er:YAG and deep disinfection and biomodulation with Nd:YAG.
Granulation tissue elimination, mechanical instrumentation of the implant surface and curettage of intraosseous or supracrestally bone defects will be accomplished using plastic curets, under irrigation with sterile saline solution. Cotton pellets soaked in sterile saline solution will be use to clean debris and remains of removed tissue.

RECRUITINGProportion of participants with treatment success
Treatment success defined as implant survival with the absence of peri-implant probing depths (PD) greater than 5 mm with concomitant bleeding/suppuration and absence of progression of peri-implant bone loss.
