Abstract

A method and system are provided for manufacturing a physical dental model. A virtual model is provided representative of at least a portion of the intra-oral cavity including at least one dental implant implanted therein, and the virtual model includes a virtual portion representative of each dental implant. The virtual spatial disposition of each such virtual portion is determined with respect to the virtual model, corresponding to a real spatial disposition of the respective implant with respect to the intra oral cavity. A physical model is then manufactured based on the virtual model, the physical model including a physical analog corresponding to each implant at a respective physical spatial disposition with respect to the physical model corresponding to the respective virtual spatial disposition of the respective virtual portion with respect to the first virtual model as already determined. In some embodiments, a jig is provided configured for maintaining a desired physical spatial disposition between the physical analog and a cavity of the physical dental model at least until the physical analog is affixed in the cavity.

Claims (45)

1. A method for making a dental model, comprising:

receiving a first intra-oral virtual model representative of at least a part of an intra-oral cavity including a first arch having at least one dental implant implanted therein in an implant spatial disposition and a second arch that is opposed to the first arch, the first arch and the second arch having an arch spatial disposition with respect to each other;

receiving an implant analog virtual model;

generating a second intra-oral virtual model by manipulating the implant analog virtual model to match the implant spatial disposition and combining the first intra-oral virtual model and the implant analog virtual model; and

outputting instructions for producing a physical dental model, corresponding to the at least a part of the intra-oral cavity and based on said second intra-oral virtual model, said physical dental model including a physical analog integrally formed therein.

2. The method of claim 1 , wherein outputting instructions for producing the physical dental model includes outputting instructions for producing a physical dental model of the first arch including a physical analog integrally formed therein.

3. The method of claim 1 , wherein outputting instructions for producing the physical dental model includes outputting instructions for producing a physical dental model of the first arch including a physical analog integrally formed therein and the second arch.

4. The method of claim 1 , further comprising:

mounting the physical dental model of the first arch including the physical analog integrally formed therein to a first end of a spacer member; and

mounting the physical dental model of the second arch to a second end of the spacer member.

5. The method of claim 4 , wherein the spacer member is sized to hold the first arch and the second arch in the arch spatial disposition with respect to each other.

6. The method of claim 5 , wherein the spacer member includes laterally spaced pins extending from opposite ends of the spacer member that engage with complementary sockets of the physical dental model.

7. The method of claim 4 , wherein the first and second arches are reversibly attached to the spacer member.

8. A method for making a dental model, comprising:

receiving a first intra-oral virtual model representative of at least a part of an intra-oral cavity including a first arch having at least one dental implant implanted therein in an implant spatial disposition and a second arch that is opposed to the first arch, the first arch and the second arch having an arch spatial disposition with respect to each other and the at least one dental implant having an impression analog coupled thereto;

receiving an implant analog virtual model representative of an implant analog of the at least one dental implant having an impression abutment attached thereto and being embedded in a jacket having an outer surface, the implant analog virtual model comprising a first portion representative of the outer surface of the jacket and a second portion representative of the impression abutment;

generating a second intra-oral virtual model by manipulating the implant analog virtual model to match the spatial disposition of the implant spatial disposition and subtracting the volume of the implant analog virtual model from the first intra-oral virtual model; and

outputting instructions for producing a physical dental model, corresponding to the at least a part of the intra-oral cavity and based on said second intra-oral virtual model, said physical dental model including a cavity formed therein, the cavity corresponding to at least a portion of the outer surface of the implant analog virtual model.

9. The method of claim 8 , wherein receiving the implant analog virtual model comprises:

embedding the implant analog into a blank of jacket material;

machining the jacket material to a desired outer surface shape; and

scanning the machined jacket material and the analog embedded therein.

10. The method of claim 8 , wherein receiving the implant analog virtual model comprises:

casting the implant analog within a jacket of casting material within a mold;

attaching the impression abutment to the implant analog; and

scanning the jacket of casting material and the implant analog therein.

11. The method of claim 8 , wherein at least a portion of the outer surface of the jacket is representative of an exposed portion of the intra-oral cavity.

12. The method of claim 8 , wherein the cavity is scaled to receive the jacket with a friction fit.

13. The method of claim 8 , wherein the cavity is scaled to receive the jacket with a press fit.

14. The method of claim 8 , wherein receiving the implant analog virtual model comprises, scanning a physical jacket with the implant analog embedded therein.

15. A method for making a dental model, comprising:

receiving a first intra-oral virtual model representative of at least a part of an intra-oral cavity including a first arch having at least one dental implant implanted therein in an implant spatial disposition and a second arch that is opposed to the first arch, the first arch and the second arch having an arch spatial disposition with respect to each other and the at least one dental implant having an impression analog coupled thereto;

receiving an implant analog virtual model comprising a first portion representative of a physical analog and a second portion representative of an impression abutment coupled thereto;

generating a second intra-oral virtual model by manipulating the implant analog virtual model to match the spatial disposition of the implant spatial disposition and subtracting the volume of the implant analog virtual model from the first intra-oral virtual model; and

outputting instructions for producing a physical dental model, corresponding to the at least a part of the intra-oral cavity and based on said second intra-oral virtual model, said physical dental model including a cavity formed therein, the cavity corresponding to at least a portion of the volume of the implant analog virtual model.

16. The method of claim 15 , wherein manipulating the implant analog virtual model to match the spatial disposition of the implant spatial disposition includes identifying areas of the implant analog virtual model and intra-oral virtual model that are common to each other.

17. The method of claim 16 , further comprising matching the spatial disposition of identified areas of the implant analog virtual model and intra-oral virtual model.

18. The method of claim 15 , further comprising:

mounting the physical model of the first arch to a first end of a spacer member; and

mounting the physical model of the second arch to a second end of the spacer member.

19. The method of claim 18 , wherein:

the physical model of the first arch comprises a first engaging base portion and the physical model of the second arch comprises a second engaging base portion; and

wherein a form and size of the spacer member, the first engaging base portion, and the second engaging base portion are configured so that the first arch and the second arch are in occlusal relationship when the physical model of the first arch is mounted to the first end of the spacer member and the physical model of the second arch is mounted to the second end of the second spacer member.

20. The method of claim 15 , wherein the cavity is scaled to receive a jacket with a friction fit.

21. The method of claim 15 , wherein the cavity is scaled to receive a jacket with a press fit.
