Treatment of Periimplantitis with Diode Laser: A Clinical Report

Carlo Maiorana/Sergio Salina/Franco Santoro

Purpose: The evaluation of the efficacy of diode laser treatment in cases of periimplantitis was the goal of this clinical research as illustrated by a case report. Materials and Methods: In addition to an oral hygiene session and one week of local prophylaxis with 0.12% chlorhexidine, each of 21 patients (bearing 23 implants) received initial treatment with ultrasonic debridement and diode laser (wavelength 810 nm) decontamination (1 to 1.5 W for 20 s, continuous wave mode) of the implant surfaces and periimplantits defects. After one week, each patient underwent flap surgery with a second, deeper ultrasound and laser decontamination, and guided bone regeneration (GBR) with purified and deproteinized bovine bone and a collagen membrane. A case report is given of one 73-year-old male patient. Results: This case, like the other 20, presented resolution of the periimplant mucositis and good improvement of the PAL index, also after 12 months. Conclusions: Laser therapy was found to efficiently reduce the bacterial contamination and inflammation. This bactericidal effect is fundamental to obtaining a good prognosis for GBR therapy. Further clinical and animal research is necessary to better evaluate all the effects of the diode laser on the bone and the soft tissue around implants and its postulated capacity to promote the new bone formation.
