Abstract

Various implant analogs and dental modeling techniques are disclosed herein. The implant analogs are versatile and can be used in traditional modeling techniques or in rapid-prototyping techniques for producing dental models.

Claims (32)

1 . A dental modeling system comprising:

a plurality of implant analogs, each of the plurality of implant analogs having a body and a shaft, wherein the shaft has a longitudinal axis and includes a first projection extending outwards from the shaft and a second projection extending outwards of the shaft, wherein the second projection is spaced along the longitudinal axis from the first projection and is positioned at an apical end of the shaft, wherein at least one of the first projection and second projection have a first rounded side and a second rounded side that opposes the first rounded side across a diameter of the shaft therefrom, and wherein the body has a groove formed about part or all of a circumference thereof; and

a first dental model having an insert with an internal bore configured to receive one of the plurality of implant analogs, wherein a wall of the insert that defines the internal bore has a larger diameter section configured to receive the body of the one of the plurality of implant analogs and a smaller diameter section configured to receive the shaft;

wherein at least one of the first projection and the second projection and the wall along the smaller diameter section are configured to create a first interference fit between the insert and the one of the plurality of implant analogs and wherein the wall of the insert and the body are configured to form a second interference fit by engagement by one of a helical protrusion along the wall of the insert engaging the body or a flowed portion of the wall of the insert being received in the groove.

2 . The dental modeling system of claim 1 , wherein the wall of the insert that defines the larger diameter section and the body are configured to create the second interference fit between the insert and the one of the plurality of implant analogs and wherein the first and second projections are positioned relatively nearer an apical end of each of the plurality of implant analogs when compared to a position of the groove in the body.

3 . The dental modeling system of claim 2 , wherein groove in the body is positioned relatively nearer a coronal end of each of the plurality of implant analogs when compared to positions of the first and second projections.

4 . The dental modeling system of claim 1 , wherein each of the plurality of implant analogs further comprises an internal bore with a tapered section and a threaded section, the threaded section being positioned apically of the tapered section.

5 . The dental modeling system of claim 4 , wherein the tapered section is tapered by between about 14-45 degrees.

6 . The dental modeling system of claim 4 , wherein the internal bore further comprises a polygon-shaped recess positioned between the tapered section and the threaded section.

7 . The dental modeling system of claim 4 , wherein the first projection and the second projection each have a pair of flat sides that define the first projection and the second projection in combination with the first rounded side and the second rounded side.

8 . The dental modeling system of claim 1 , wherein the first projection of each of the plurality of implant analogs has a tapered surface, and the tapered surface of the first projection of a first implant analog of the plurality of implant analogs is configured to be engaged with the wall.

9 . A dental modeling system comprising:

a plurality of implant analogs, each of the plurality of implant analogs having a body and a shaft, wherein the shaft has a longitudinal axis and includes a first projection extending outwards from the shaft and a second projection extending outwards of the shaft, wherein the second projection is spaced along the longitudinal axis from the first projection and is positioned at an apical end of the shaft, and wherein at least one of the first projection and second projection have a first rounded side and a second rounded side that opposes the first rounded side across a diameter of the shaft therefrom; and

a first dental model having an insert with an internal bore configured to receive one of the plurality of implant analogs, wherein a wall of the insert that defines the internal bore has a larger diameter section configured to receive the body of the one of the plurality of implant analogs and a smaller diameter section configured to receive the shaft; and

wherein at least one of the first projection and the second projection and the wall along the smaller diameter section are configured to create a first interference fit between the insert and the one of the plurality of implant analogs;

wherein the wall of the insert that defines the larger diameter section and the body are configured to create a second interference fit between the insert and the one of the plurality of implant analogs; and

wherein the second interference fit is formed by one of a helical protrusion along the wall of the insert in the larger diameter section engaging the body or a flowed portion of the wall of the insert being received in a groove formed about part or all of a circumference of the body.

10 . The dental modeling system of claim 9 , wherein each of the plurality of implant analogs further comprises an internal bore with a tapered section and a threaded section, the threaded section being positioned apically of the tapered section.

11 . The dental modeling system of claim 10 , wherein the tapered section is tapered by between about 14-45 degrees.
