  • Polymerization temperature test element
    Patent number: 7445440
    Abstract: A polymerization temperature test element is provided for a polymerization device of the type, in particular, for polymerizing dental products. The polymerization temperature test element includes a base element and a receipt region centrally disposed on the base element and operable to receive the mass to be polymerized. The energy source of the polymerization device irradiates the mass to be polymerized with one or both of light radiation and thermal radiation to effect polymerization of the mass and the base element and the receipt region are configured so as to be subjected to the respective light and thermal radiation emitted by the energy source. Accordingly, the polymerization temperature test element provides an indication, via color-temperature indicators which change color or brightness at discrete temperatures, that a target polymerization temperature has been reached during irradiation of the mass.
