System and process for duplication of dentures

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.
