  • Patent number: 6398550
    Abstract: The invention involves an impression tray for dental prosthetics. In order to perform the hardening of the impression material without having to have a worker manually hold the impression tray for the duration of the hardening, it is proposed to construct the impression tray so that it can be held by the patient's biting down. In this process it is proposed to equip the bottom of the impression material with a thickness that is enlarging from the ends, in order to obtain during biting only forces normal to the surfaces of the bottom. Instead of equipping the entire bottom in this self-reinforcing manner, it also possible to provide only a separately inserted casting channel with this special shape, which is also constructed in a special embodiment in such a manner that it can used in the impression trays known thus far.
