Abstract
A dental laser comprises a hand piece having a grip region and a treatment tip with an outlet point, arranged at a distal end, for laser light, and further comprises a light source and light conduction means for providing laser light at the outlet point. The laser light has a wavelength of 445±20 nm, in particular, 445±10 nm and more particularly 445±5 nm, and an optical power output is provided at the outlet point in a power range of at least 2 W, advantageously at least 3 W and, in particular, 3.5 W. In another dental laser the laser light has a wavelength of 410±10 nm, and an optical power output is provided at the outlet point in a power range of no less than 1 W to no more than 2 W.
Claims11
A method of cutting dental tissue comprising:
- providing a handpiece including a grip region, a treatment tip arranged at a distal end of the handpiece, and a light conduction device disposed in the handpiece and configured to provide laser light to cut the dental tissue;
- configuring the handpiece to operate in a first mode of operation wherein the laser light is configured to have a wavelength and optical power output combination of 445±20 nm and 2 W to 5 W;
- directing the laser light in a light path from a light source to the dental tissue, the directing starts from the light source, through an outlet point of the treatment tip and onto the dental tissue to non-contactly cut the dental tissue, wherein the dental tissue is processed substantially by energy generated in the dental tissue by absorption of the laser energy and not thermal transmission of energy from the treatment tip to the dental tissue;
- and
- configuring the handpiece to operate in a second mode of operation wherein the laser light is configured to have a wavelength and optical power output combination of 410±10 nm and 1 W to 2 W, wherein the handpiece is guided over the dental tissue in a contact manner to cut said dental tissue using the treatment tip.
