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.
Claims17
A computer implemented method for duplicating dentures from an existing denture, the method comprising the steps of:
- taking a scan of the existing denture comprising existing teeth and an existing denture base;
- creating a digital three dimensional model comprising digital scanned teeth and a digital scanned denture base from the scan of the existing denture, wherein the creating comprises:
- fitting digital denture teeth from a library to a digital denture in response to the digital three dimensional model;
- offsetting the digital scanned teeth by a predetermined amount to create offset digital denture teeth, wherein the offsetting comprises:
- selecting denture teeth that are a closest fit to the existing teeth from among the library;
- adding a thickness to the digital scanned teeth in response to the selecting, the thickness comprising the predetermined amount;
- subtracting the offset digital denture teeth from the digital scanned denture base to create pockets in the digital scanned denture base, said pockets being larger than the digital denture teeth prior to the step of offsetting the digital scanned teeth;
- removing margins from the digital denture;
- manufacturing a first denture base from the digital three dimensional model, wherein the manufacturing comprises fabricating pockets in the first denture base corresponding to the offset digital denture teeth in response to the digital three dimensional model;
- and
- installing teeth corresponding to the digital denture teeth to the first denture base.
A computer implemented method for duplicating dentures from an existing denture comprising the steps of:
- receiving patient data comprising a scan of an existing denture comprising existing teeth and an existing denture base;
- creating a digital three dimensional model comprising digital scanned teeth and a digital scanned denture base from the patient data,
- wherein the creating of the digital three dimensional model comprises:
- fitting digital denture teeth from a library to a digital denture base in response to the digital three dimensional model;
- offsetting the digital scanned teeth by a predetermined amount to create offset digital denture teeth, wherein the offsetting comprises:
- selecting denture teeth that are a closest fit to the existing teeth from among the library;
- adding a thickness to the digital scanned teeth in response to the selecting, the thickness comprising the predetermined amount;
- subtracting the offset digital denture teeth from the digital scanned denture base to create pockets in the digital scanned denture base, said pockets being larger than the digital denture teeth prior to the step of offsetting the digital scanned teeth
- removing margins from the digital denture base
- manufacturing a first denture base based on the digital three dimensional model;
- and
- installing teeth corresponding to the digital denture teeth to the first denture base.
