Minimally Invasive Procedure Using an Er:YAG Laser for Gingival Esthetic

Abstract

Er:YAG laser, wavelength of 2,940 nm, is highly absorptive of water and can effectively ablate both soft and hard tissues. It has been demonstrated that the Er:YAG laser has minimal thermal damage on surrounding tissues when used for gingival incisions, which makes it a preferred modality over other laser wavelengths. This laser is frequently utilized in dental procedures, including gingivectomy, frenectomy, gingival pigmentation removal, and metal tattoo removal, due to its favorable wound healing properties and reduced pain. A significant advantage of the Er:YAG laser is its effectiveness when used with a thin contact tip, enabling precise and delicate procedures on both hard and soft tissues. This allows for compatibility during treatment using an operating microscope, enabling precise and localized tissue treatment without causing thermal damage. This approach is consistent with the concept of minimally invasive procedures. The article also discusses the use of this laser in the removal of melanin pigment and metal tattoos, where the laser’s selective and minimally invasive tissue vaporization provides effective and satisfactory results for patients. A new technique, Er:YAG laser micro-keyhole surgery (EL-MIKS), has been introduced for the removal of extensive metal tattoos.
