Use of diode laser in Peri-implantitis Treatment Report of 3 Cases

Report of 3 Cases

Abstract

Los implantes dentales se utilizan ampliamente para el reemplazo de dientes y se han convertido en el "estándar de oro" de las terapias protésicas en odontología. Dado el mayor uso de estos, las investigaciones epidemiológicas recientes han mostrado altas tasas de prevalencia de enfermedad periimplantaria. En el presente estudio se presentan tres casos clínicos diagnosticados de periimplantitis. Todos los casos presentaron mayor profundidad al sondaje periimplantario en relación a controles previos, supuración, sangrado y pérdida ósea confirmada por tomografía computarizada de haz cónico. El tratamiento indicado para todos los casos fue un  joint therapy between a mechanical ultrasound treatment with the use of plastic tips (P.I EMS®, Switzerland) and laser therapy. For laser therapy, a 940 nm diode laser equipment was used (Biolase®, USA) with a power of 2W in continuous laser beam mode, using a 300 µm tip. The diode laser does not damage the titanium surface and is capable of decontaminating the rough surfaces of the implants. In this report, the use of a combined mechanical and laser therapy was effective in all cases. In clinical controls, the peri-implant mucosa did not show signs of suppuration or bleeding, and the depth on probing was decreased. The bone level was controlled through a cone beam computed tomography and no significant changes were evidenced. At present, the clinical evidence for peri-implant treatment using phototherapy is still limited. However, the laser offers a novel technical approach that is completely different from mechanical instruments and has several beneficial effects, so it can play an important role in the resolution of peri-implantitis.
