System and process for duplication of dentures

Abstract

Systems and processes for the duplication of dentures from existing dentures. The interior and exterior of the dentures are scanned and a best fit procedure is used to create a fully digitized denture. The denture teeth are selected from a library that is the closest fit to the original denture teeth. The library teeth are offset a preset distance to compensate for the best fit. The teeth are then subtracted from the digitized denture. The margins of the denture are then cleaned after subtracting the teeth. The denture base is then ready for manufacturing. The teeth are then installed onto the denture base and provided to the patient.

1 . A system for creating a duplicate denture from an existing denture, the system comprising:
 a processing device configured to execute computer-readable code;   a memory device connected to said processing device for storing computer-readable code;   an interface for receiving data relevant to a particular patient and storing said data in said memory device;   a rendering engine for creating a digital three dimensional model of the existing dentures from scans of the existing image;   a selection engine for selecting the denture teeth that best fits the digital denture model;   a manipulation engine adding a preset amount to the denture teeth, for subtracting the denture teeth from the denture model and for cleaning the margins of the denture model.
