Abstract
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).
Claims5
A method of coloring a dental object (101), comprising the steps of:
- receiving (S101) the dental object (101) comprising polychromic glass, polychromic glass-ceramic or a mixture thereof in a chamber (103);
- first emitting (S102) 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.
