For the past fifteen years, lasers have been used successfully in dentistry. Each laser is specific by its wavelength. The absorption of laser radiation in hard or soft tissues depends on this wavelength. Laser-assisted dental surgery techniques have become recognized and must be part of our therapeutic arsenal. Their integration in implantology opens new possibilities. Among the lasers used in implantology is the diode laser which has interesting characteristics in the fields of decontamination and bio-stimulation, but can also be used for its ablative action on soft tissues. However, the success of an assisted laser treatment remains conditioned by the adequacy between the clinical case, the establishment of a good indication and the choice of the adapted laser material, which implies and requires a good knowledge by the practitioner of the respective modes of action of the laser, its main indications and its therapeutic limits.
