Laser-Assisted Therapy for the Treatment of Peri-implantitis. Part I. Clinical Outcomes.

The purpose of this 12-month randomized, controlled clinical trial was to evaluate the efficacy of a monotherapy protocol with the neodymium-doped yttrium aluminum garnet (Nd:YAG) laser for treatment of peri-implantitis. Twenty patients with 36 implants exhibiting probing pocket depths (PPDs) > 4 mm and evidence of radiographic bone loss (RBL) were randomly divided into two groups. The test group was treated with the Nd:YAG laser, and the control group was managed with mechanical debridement only.
