ABSTRACT:
An apparatus for treating, particularly bleaching, dental objects, such as dentures or parts thereof, made of synthetic material includes a support disposed in a drawer for receiving the objects and a lamp disposed above the drawer for emitting radiation in a spectral range (approximately 400 to 500 nm) suitable for the bleaching process. An upper reflector surrounding the lamp reflects from the total radiation emitted by the lamp mainly the portion lying within the said spectral range while it transmits the remaining radiation to the outside. An inner surface of the drawer forms a lower reflector. The support also consists of reflective material and has a central semi-spherical projection to ensure that the object positioned on the support so as to surround the projection is irradiated from all sides.
