Dental laser for the treatment of soft tissue

Abstract

A dental laser comprises a hand piece ( 100 ) having a grip region ( 100 a ) and a treatment tip ( 101 ) with an outlet point ( 101 a ), arranged at a distal end, for laser light ( 102 ), and further comprises a light source ( 103 ) and light conduction means ( 105 ) for providing laser light ( 102 ) at the outlet point ( 101 a ). The laser light ( 102 ) has a wavelength ( 104 ) 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 ( 102 ) has a wavelength ( 104 ) of 410±10 nm, and an optical power output is provided at the outlet point ( 101 a ) in a power range of no less than 1 W to no more than 2 W.

1 . Dental laser, comprising a hand piece having a grip region and having a treatment tip with an outlet point, arranged at a distal end, for laser light; further comprising a light conduction means, arranged in the handpiece, for providing laser light at the outlet point, with said laser light coming from a light source, arranged inside or outside the handpiece, wherein the laser light has a wavelength of 445±20 nm, and that an optical power output is provided at the outlet point in a power range of no less than 2 W to no more than 5 W. 
     
     
         2 . Dental laser, as claimed in  claim 1 , wherein the optical power output at the outlet point can be changed to a different power range, with the different power range running from at least 1 W to less than 2 W. 
     
     
         3 . Dental laser, comprising a hand piece having a grip region and having a treatment tip with an outlet point, arranged at a distal end, for laser light; further comprising a light conduction means, arranged in the handpiece, for providing laser light at the outlet point, with said laser light coming from a light source, arranged inside or outside the handpiece, wherein the laser light has a wavelength of 410±10 nm; and that 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. 
     
     
         4 . Dental laser, as claimed in  claim 1 , wherein the light source comprises at least one laser diode. 
     
     
         5 . Dental laser, as claimed in  claim 1 , wherein the treatment tip for providing laser light at the outlet point has application fibers between 150 μm and 350 μm in diameter. 
     
     
         6 . Dental laser, as claimed in  claim 1 , wherein a coolant line is arranged on or in the handpiece; and that there is an outlet opening, from which coolant exits in a directed manner, wherein the amount of cooling ranges from 0.1 to 10 ml/min. 
     
     
         7 . Dental laser, as claimed in  claim 6 , wherein the coolant has a disinfecting effect. 
     
     
         8 . Method for the surgical treatment of the human or animal body with the aid of laser light, using the dental laser of  claim 1 . 
     
     
         9 . Dental laser, as claimed in  claim 3 , wherein the light source comprises at least one laser diode. 
     
     
         10 . Dental laser, as claimed in  claim 3 , wherein the treatment tip for providing laser light at the outlet point has application fibers between 150 μm and 350 μm in diameter. 
     
     
         11 . Dental laser, as claimed in  claim 3 , wherein a coolant line is arranged on or in the handpiece; and that there is an outlet opening, from which coolant exits in a directed manner, wherein the amount of cooling ranges from 0.1 to 10 ml/min. 
     
     
         12 . Dental laser, as claimed in  claim 11 , wherein the coolant has a disinfecting effect. 
     
     
         13 . Method for the surgical treatment of the human or animal body with the aid of laser light, using the dental laser of  claim 3 .
