Treatment of periodontal disease with the Lightwalker Laser is called Wavelength-Optimized Periodontal Therapy (WPT) and utilizes both the Er:YAG laser and Nd:YAG laser.
Utilizing both Er:YAG and Nd:YAG laser wavelenfths in a single treatment makes optimum use of the unique laser-tissue interaction characteristics of each wavelength. For example, Nd:YAG laser energy is superior for coagulation and deep disinfection, while Er:YAG is uniquely efficient at gently removing the infected surface tissue and calculus from the root surface. Combined, they can dramatically improve the outcome of laser-assisted treatments, guaranteeing maximum safety and efficacy.
