  • Patent number: 4608020
    Abstract: The time for making artificial dentures is much shortened by using the tubular teeth of the invention for the replacement of the lateral teeth. A casting pattern is made by fastening in a wax baseplate--in addition to standard-size frontal teeth--longitudinally perforated hollow lateral teeth which are anatomically true on their outside. These tubular teeth are now completely filled with wax and the pattern is placed into an articulator together with the opposite denture and the superfluous wax is removed from the top of the teeth by motion of the articulator in a conventional manner. The smoothed-down pattern is placed into the patient's mouth for final adjustment and is then used for making a casting mold. After melting the wax out of the baseplate and the tubular teeth, the mold is filled with a plastic material in liquid stage which also fills the tubular teeth up to their upper surfaces. The denture is now ready and does not require additional fitting and grinding in the patient's mouth.
