Abstract

Claims (21)

1 . A denture duplicating method without requiring a clinical fitting appointment by a dentist, comprising:

providing a mold-forming kit to a wearer;

forming a mold of a denture with the mold-forming kit;

receiving the mold of the denture from the wearer;

scanning a mold of the denture for the wearer using a scanner coupled to a controller;

generating, by the controller, a denture specifications file based on a scan of the mold of the denture;

storing, by the controller, the denture specifications file in non-transitory computer readable memory wherein the mold is formed as a negative impression of the wearer's original denture and retains anatomical details of the original denture;

in response to receiving a computer-based request from a user, automatically retrieving, by the controller, the denture specifications file and loading, by the controller, the denture specifications file into a milling design application executed by the controller to generate a replacement denture platform design;

in response to receiving an electronic payment from the user, automatically instructing, by the controller, a communicatively coupled three-dimensional printer to perform a print operation; and

in response to the instructing, automatically printing the replacement denture platform based on the replacement denture platform design, wherein the replacement denture platform can then be sent to the wearer; and

providing the replacement denture platform to the wearer.

2 . The denture duplicating method of claim 1 , wherein the mold of the denture is a three-dimensional replica of the wearer's original denture.

3 . The denture duplicating method of claim 2 , wherein the mold is created by injecting a substance into a hollow space matching the wearer' s original denture.

4 . The denture duplicating method of claim 1 , wherein the denture specifications file further comprises:

data relating to surface geometry of the scanned mold of the denture comprising curvature, depth profiles, and undercut locations of the original denture's surfaces.

5 . The denture duplicating method of claim 4 , wherein the denture specifications file further comprises:

a STL file usable in a stereolithographic CAD program to generate a printable 3D model of the replacement denture platform.

6 . The denture duplicating method of claim 1 , wherein the replacement denture platform has a coloring that is customizable.

7 . The denture duplicating method of claim 1 , wherein the replacement denture platform is coupled with milled teeth prior to being sent to the wearer that are manufactured based on tooth positioning extracted from the original denture mold.

8 . The denture duplicating method of claim 1 , wherein the scanner further comprises:

a multiple-axis three-dimensional scanner.
