Abstract

A system can be configured to record a position and orientation of a dental component. The system can include a coping and a replica. The coping can include an anti/rotational feature that is configured to mate with an anti-rotational feature of a dental component. The coping can also include an orientation feature that is configured to convey the orientation of the dental component. The replica can include a first anti-rotational feature that corresponds to the anti-rotational feature of the dental component. The replica can also include a second anti-rotational feature that does not correspond to the anti-rotational feature of the dental component.

First claim

What is claimed is:

1 . A system configured to record a position and an orientation of a dental component, the system comprising:
a coping comprising:
an anti-rotational feature that is configured to mate with an anti-rotational feature of the dental component, and
an orientation feature that is configured to convey the orientation of the dental component; and
a replica configured to replicate the position and the orientation of the dental component in relation to adjacent teeth or soft tissue, the replica comprising:
a first anti-rotational feature that corresponds to the anti-rotational feature of the dental component, the first anti-rotational feature configured to mate with the anti-rotational feature of the coping, and
a second anti-rotational feature that does not correspond to the anti-rotational feature of the dental component.

2 . The system of claim 1 , wherein the coping comprises an impression coping that is configured to be embedded in an impression medium to record the position and orientation of the dental component, or
wherein the coping comprises a scan body that is configured to be scanned to record the position and orientation of the dental component.

3 . The system of claim 1 , wherein the coping comprises:
an external surface comprising the orientation feature; and an internal surface comprising the anti-rotational feature, wherein at least one of the orientation feature and the anti-rotational feature of the coping comprise a protrusion, a recess, a pin, or a groove.

4 . The system of claim 1 , wherein the second anti-rotational feature of the replica is positioned on the first anti-rotational feature of the replica.

5 . The system of claim 1 , wherein the second anti-rotational feature of the replica protrudes from a surface configured to mate with an adjacent component, wherein the adjacent component comprises at least one of the coping, an abutment, and a prosthesis.

6 . The system of claim 1 , wherein at least one of the first anti-rotational feature and the second anti-rotational feature of the replica comprise a protrusion, a recess, a pin, or a groove.

7 . The system of claim 1 , further comprising the dental component, wherein the dental component comprises a dental implant or an adapter configured to mate with the dental implant.

8 . The system of claim 1 , wherein the system is configured to align the dental component with another dental component, wherein the dental component and the another dental component have non-circular outer cross-sectional interfaces.

9 . The system of claim 8 , further comprising the another dental component, wherein the another dental component is configured to mate with the second anti-rotational feature of the replica, but not with the first anti-rotational feature of the replica, wherein the another dental component comprises at least one of an abutment and a prosthesis.

10 . A method of fabricating a second dental component that is configured to align with a first dental component in a patient's mouth, the method comprising:
mating a replica with a coping, wherein the coping has an orientation feature that has been recorded with respect to the first dental component to convey a position and an orientation of the first dental component in relation to adjacent teeth or soft tissue, the replica comprising a first anti-rotational feature that corresponds to an anti-rotational feature of the first dental component, the first anti-rotational feature configured to mate with the anti-rotational feature of the coping, the replica further comprising a second anti-rotational feature that does not correspond to the anti-rotational feature of the first dental component; forming a model of at least a part of the patient's mouth adjacent the replica mated with the coping; unmating the coping from the replica; and creating the second dental component such that the second dental component is configured to mate with the second anti-rotational feature of the replica, but not with the first anti-rotational feature of the replica.

11 . The method of claim 10 , further comprising:
mating the coping with the first dental component, the coping comprising an anti-rotational feature configured to mate with the anti-rotational feature of the first dental component; recording the orientation feature of the coping mated with the first dental component to record the position and orientation of the first dental component; and unmating the coping from the first dental component.

12 . The method of claim 10 , wherein the orientation feature has been recorded by embedding the orientation feature in an impression medium or by scanning the orientation feature.

13 . The method of claim 10 , wherein the first dental component and the second dental component have non-circular outer cross-sectional interfaces.

14 . The method of claim 10 , wherein the first dental component is a dental implant or an adapter configured to mate with the dental implant.

15 . The method of claim 10 , wherein creating the second dental component comprises creating at least one of an abutment and a prosthesis.

16 . The method of claim 10 , wherein unmating the coping from the replica comprises unmating the coping from the replica such that the replica remains in the model.

17 . The system of claim 1 , wherein the second anti-rotational feature of the replica comprises a pin, the pin protruding from a surface configured to mate with an adjacent component.

18 . The system of claim 8 , wherein the non-circular outer cross-sectional interfaces are trioval or quadrioval interfaces.

19 . The method of claim 13 , wherein the non-circular outer cross-sectional interfaces are trioval or quadrioval interfaces.
