Exposure device for illuminating a dental object
An exposure apparatus ( 100 ) for illuminating a dental object ( 101 ), including a chamber ( 103 ) for receiving the dental object ( 101 ); and a radiation source ( 105 ) for emitting radiation having a wavelength shorter than 350 nm into the chamber ( 103 ).
1 . A method of coloring a dental object ( 101 ), comprising the steps of:
receiving (S 101 ) the dental object ( 101 ) comprising polychromic glass, polychromic glass-ceramic or a mixture thereof in a chamber ( 103 );
first emitting (S 102 ) radiation from a radiation source ( 105 ) having a wavelength smaller than 350 nm into the chamber ( 103 );
thereafter exposing the dental object ( 101 ) to infrared radiation from an infrared radiation source ( 113 );
wherein the dental object is rotated in front of the radiation source ( 105 ), the infrared radiation source ( 113 ), or both by a moving device on which the dental object ( 101 ) is arranged; and
wherein coloring of the dental object is initiated by the radiation having a wavelength smaller than 350 nm and the coloring of the dental object is completed by the infrared radiation.
2 . The method according to claim 1 ,
wherein the dental object ( 101 ) is moved while the radiation having a wavelength smaller than 350 nm is being emitted and/or while the infrared radiation is being emitted.
3 . The method according to claim 1 ,
wherein the radiation source ( 105 ), and/or the infrared radiation source ( 113 ) is moved while emitting radiation.
4 . The method according to claim 1 ,
wherein the infrared radiation comprises a wavelength equal to or greater than 700 nm.
5 . The method according to claim 1 ,
wherein the polychromic glass and polychromic glass-ceramic comprise an oxidizable component and a reducible coloring component.
