Abstract
Laser therapy is a contemporary therapeutic technique that can be used effectively as an adjunct to conventional mechanical means of disinfection in periimplantitis. However, there is a need to reach consensus on the standardisation of laser-related parameters that could produce the most favourable results with regard to peri-implant anti-infectious therapy. The aim of current study is determination of the temperature changes in and around the implant during laser irradiaton with ER:YAG, COâ?? and diode lasers by means of integrated digital system with thermocouples. The interaction between laser light and metal surfaces is determined mainly by the degree of absorption and reflection. Each metal has a certain ability to reflect, which depends on the specific wavelength of the laser. The reflection factor for titanium in the Er:YAG laser is 71% and rises to 96% for CO2. The results, which were obtained in a thermocouple study, show that the laser with the best physico-biological parameters is the Er:YAG laser. Even during prolonged operation does not lead to a temperature increase in the implant interface, and in certain areas it decreases slightly. This phenomenon is favored by the water cooling which the apparatus works, and the pulse mode of the beam that allows for thermal relaxation of tissues.
