Abstract

Various implant analogs, model, and base designs are disclosed herein. In one example, an implant analog can include a main body and a second component. The main body can have an axis of symmetry and a passage therein. The second component can be received in the passage so as to extend substantially transverse to the axis of symmetry.

Claims

1. A system for simulating a mouth of a patient, comprising:

first and second implant analogs each having a main body, a solid body portion, a bore through the solid body portion, and a component configured to extend transverse to the main body when received in the bore; and

a model having first and second primary passages with the first primary passage having first and second transverse passages associated therewith and the second primary passage having third and fourth transverse passages associated therewith, wherein the first transverse passage extends transverse to the first primary passage, the second transverse passage extends transverse to the first primary passage, the third transverse passage extends transverse to the second primary passage and the fourth transverse passage extends transverse to the second primary passage,

wherein the first and second primary passages extend entirely through the model and each has a first opening to a first coronal side of the model and a second opening to an opposing second apical side of the model, and wherein the first, second, third and fourth transverse passages each have a corresponding opening only to the apical side of the model that communicates with the second opening,

wherein the first primary passage, the first transverse passage and the second transverse passage communicate such that the first implant analog is assembled outside the model with the component received in the bore and the assembled first implant analog is configured to be inserted through the second opening and the corresponding opening and into collectively the first primary passage, the first transverse passage and the second transverse passage, wherein the model is configured for the first primary passage to receive the main body of the first implant analog and for the first opening to allow a portion of the main body to extend from the first opening and protrude from the first side, and the first transverse passage and the second transverse passage in combination are configured to receive portions of the component when assembled to the main body,

wherein the second primary passage, the third transverse passage and the fourth transverse passage communicate such that the second implant analog is assembled outside the model with the component received in the bore and the assembled second implant analog is configured to be inserted through the second opening and the corresponding opening and into collectively the second primary passage, the third transverse passage and the fourth transverse passage, wherein the model is configured for the second primary passage to receive the main body of the second implant analog and for the first opening to allow a portion of the main body to extend from the first opening and protrude from the first side, and the third transverse passage and the fourth transverse passage in combination are configured to receive portions of the component when assembled to the main body, and

wherein the first and second transverse passages include one or more fixation or retention mechanisms configured to contact and affix the component of the first implant analog to the model with the main body protruding from the first side, and the third and fourth transverse passages include one or more fixation or retention mechanisms configured to contact and affix the component of the second implant analog relative to the model with the main body protruding from the first side.

2. The system of claim 1, further comprising:

a base having a primary surface and a plurality of holes therein, the holes opening along the primary surface; and

one or more positioning elements having an apical portion adapted to be received in at least one of the holes, wherein the positioning elements have a coronal portion adapted to be received in the model.

3. The system of claim 1, wherein the first and second implant analogs each has a different sized main body.

4. The system of claim 1, wherein the model is configured to represent an accurate model of the patient'"'"'s jaw.

5. The system of claim 1, wherein the model includes a working surface that is configured to receive one or more components that simulate abutments or other dental implant components.

6. The system of claim 1, wherein the bore through the solid body portion of each of the first and second implant analogs comprises an entry opening on a first side of the solid body and an exit opening on a second side of the solid body, the entry and exit openings being tapered.

7. The system of claim 1, wherein the first and second implant analogs each has a coronal end with an attachment member configured to receive a second component that simulates a dental implant, and the attachment member and the bore through the solid body portion do not intersect within the solid body portion.

8. The system of claim 1, wherein the one or more fixation or retention mechanisms comprise the first, second, third and fourth transverse passages having tapered walls, detents, or tabs configured to contact and affix the components of the first and second implant analogs, respectively, relative to the model.

9. The system of claim 1, wherein the second side comprises a non-model side of the model, and wherein the first side comprises an anatomical side of the model.

10. The system of claim 1, wherein the first primary passage is angled relative to the second primary passage.

11. A method for affixing an implant analog to a model, comprising:

assembling a first component with a first main body to form a first implant analog by inserting the first component into a receptacle in the first main body, wherein the first implant analog is assembled external to the model;

assembling a second component with a second main body to form a second implant analog by inserting the second component into a receptacle of the second main body, wherein the second implant analog is assembled external to the model;

passing the assembled first implant analog through the model via insertion through a first opening at an apical side of the model and via a first primary passage configured to receive the first main body and a first transverse passage configured to receive the first component;

passing the assembled second implant analog through the model via insertion through a second opening at the apical side of the model and via a second primary passage configured to receive the second main body and a second transverse passage configured to receive the second component, wherein the first and second transverse passages intersect and are transverse, respectively, to the first primary passage and the second primary passage, wherein the first and second primary passages extend entirely through the model from the apical side to an opposing coronal side, and wherein the model has third openings at the coronal side configured to allow a portion of the main body extend therethrough and to protrude from the coronal side; and

affixing the first and second components within the first and second transverse passages, respectively, thereby coupling the first and second implant analogs to the model with the main body protruding from the coronal side.

12. The method of claim 11, wherein each of the first and second implant analogs has a coronal end with an attachment member configured to receive the second component that simulates a dental implant, and the attachment member and a bore are spaced from one another and do not intersect with one another within the first or second body.

13. The method of claim 11, wherein the receptacle of the first implant analog comprises an entry opening on a first side of the main body and an exit opening on a second side of the main body, the entry and exit openings being tapered.

14. The method of claim 11, wherein the first and second transverse passages comprise one or more fixation or retention mechanisms, and the method further comprises contacting the first and second components with the one or more fixation or retention mechanism within the first and second transverse passages to affix the first and second components relative to the model, respectively, using the fixation or retention mechanisms.

15. The method of claim 14, wherein the one or more fixation or retention mechanisms comprise the first and second transverse passages having tapered walls, detents, or tabs configured to contact and affix the first and second components, respectively, relative to the model.

16. The method of claim 11, wherein the first primary passage is angled relative to the second primary passage.
