when cutting hard tissue with an erbium laser

The WaterLase iPlus tissue cutting system is a unique device with diverse, hard- and soft-tissue dental applications. The Erbium YAG laser was the first laser approved by the FDA for cutting hard tissue such as tooth and bone. J Periodontal Res. Also, cutting through gingival tissue is obviously very different from cutting into bone. The 9300-nm CO 2 laser wavelength is highly absorbed in the water and mineral (phosphate and carbonate) content of hard tissue, so this laser is extremely effective in vaporizing enamel. That's when I entered the erbium world, which just left me more frustrated than happy. It utilizes advanced laser and water atomization technologies to safely and effectively cut, shave, contour, roughen, etch, and resect oral hard-tissue, and direct laser energy to Native carbon dioxide lasers have been used only for soft-tissue procedures, as the wavelength is highly absorbed by water. Unlike a bur though, there is no tactile feedback . Lasers of different wavelengths produce different effects on tissue. The primary use of this laser, however, is to remove decayed parts of a tooth in preparation for a filling.
