Many oral tissue pathologies and healthy oral soft tissues require special treatments. This report presents the use of the Er:YAG laser with an X-Runner handpiece in QSP mode for three different clinical situations: leukoplakia removal, implant exposure during the second stage of implant placement, and a hyperpigmentation treatment. In each case, the treatment was based on the principle of laser ablation, with excellent coagulation and precision. Automatic guidance of the laser beam allowed higher repetitions to be used, and consequently the procedures were completed faster. After the treatments, a perfect healing process, with no recurrence of the lesion or other potential complications, was observed. Faster healing significantly shortened the prosthetic reconstruction time.
