Abstract

Claims (37)

1. A method of developing a custom-abutment for attachment to a dental implant in a mouth of a patient, comprising:

determining a type of the dental implant in the mouth of the patient;

selecting a scanning member from a set of scanning members based on the determined type of the dental implant, each of the scanning members in the set having a head portion coupled to a body portion, the head portions being identical for each of the scanning members in the set, the body portions being different for each of the scanning members in the set, the body portions each having a non-rotational feature that is configured to be coupled with a different type of non-rotational dental implant feature, the head portion having (i) a top surface indicative of a first characteristic of the dental implant, (ii) a first side surface that is substantially flat and indicative of a second characteristic of the dental implant, the first side surface of the head portion being parallel with at least one side surface of the non-rotational feature of the body portion, and (iii) a second side surface that is curved for aiding in distinguishing the second side surface from the first side surface, the second side surface opposing the first side surface;

attaching the selected one of the scanning members to the dental implant in the mouth of the patient;

determining, via scanning the head portion of the attached scanning member, the first characteristic and the second characteristic of the dental implant to gather information for manufacturing the custom-abutment; and

developing the custom abutment based on the information from the first characteristic and the second characteristic of the attached scanning member.

2. The method of claim 1 , wherein the top surface of the head portion is substantially flat.

3. The method of claim 2 , wherein the top surface of the head portion and the first side surface of the head portion are perpendicular.

4. The method of claim 3 , wherein the second side surface that opposes the first side surface is perpendicular to the top surface.

5. The method of claim 1 , wherein the top surface of the head portion is located a predetermined distance above a support surface of the dental implant, the first characteristic being the location of the support surface of the dental implant.

6. The method of claim 5 , wherein the predetermined distance is about 10 millimeters.

7. The method of claim 1 , wherein the different types of non-rotational dental implant features include internal non-rotational socket features and external non-rotational boss features.

8. The method of claim 1 , wherein the different types of non-rotational dental implant features are provided by different manufacturers of dental implants.

9. The method of claim 1 , wherein each of the scanning members in the set is configured to be coupled with a different dental implant provided by different manufacturers.

10. The method of claim 1 , wherein the determining the type of the dental implant includes determining whether a gingival end of the dental implant has an internal non-rotational socket feature or an external non-rotational boss feature.

11. The method of claim 10 , wherein the determining the type of the dental implant further includes determining a diameter of the internal non-rotational socket feature or the external non-rotational boss feature.

12. The method of claim 1 , wherein the first characteristic provides information regarding a location of a supporting surface of the dental implant and wherein and the second characteristic provides information regarding an orientation of a non-rotational feature of the dental implant.

13. The method of claim 1 , wherein the head portion has a length, a width, and a thickness, the length of the head portion being greater than a maximum diameter of the body portion.

14. The method of claim 13 , wherein the body portion of the attached scanning member has a length such that the head portion does not interfere with adjacent teeth in the mouth of the patient irrespective of the orientation of the non-rotational feature of the dental implant.

15. A method of developing a custom-abutment for attachment to a dental implant in a mouth of a patient, comprising:

non-rotationally coupling a scanning member to the dental implant in the mouth of the patient, the scanning member having a head portion coupled to a body portion which forms a generally “T” shape, the body portion having a non-rotational feature, the head portion having (i) a top surface indicative of a first characteristic of the dental implant, (ii) a first side surface that is substantially flat and indicative of a second characteristic of the dental implant, the first side surface of the head portion being parallel with at least one side surface of the non-rotational feature of the body portion, and (iii) a second side surface that is curved for aiding in distinguishing the second side surface from the first side surface, the second side surface opposing the first side surface;

scanning at least a portion of the mouth of the patient to create scan data, the portion of the mouth including the scanning member;

analyzing the scan data to determine the first characteristic and the second characteristic of the dental implant for use in manufacturing the custom-abutment; and

developing the custom abutment based on the scan data, the first characteristic, and the second characteristic.

16. The method of claim 15 , wherein the top surface of the head portion is substantially flat and wherein the top surface is perpendicular to the first side surface.

17. The method of claim 16 , wherein the second side surface that opposes the first side surface is perpendicular to the top surface.

18. The method of claim 15 , wherein the first characteristic provides information regarding a location of a support surface of the dental implant and wherein and the second characteristic provides information regarding an orientation of a non-rotational feature of the dental implant.

19. A method of manufacturing a custom dental abutment for mating with a dental implant, comprising:

scanning a model of a patient's dental conditions, the model including a dental implant analog, teeth models, and a scanning member having a head portion coupled to a body portion, the scanning member having a generally “T” shape, the body portion having a non-rotational feature that is configured to be non-rotationally coupled to the dental implant analog, the head portion having (i) a top surface indicative of a first characteristic of the dental implant analog, (ii) a first side surface that is substantially flat and indicative of a second characteristic of the dental implant analog, the first side surface of the head portion being parallel with at least one side surface of the non-rotational feature of the body portion, and (iii) a second side surface that is curved for aiding in distinguishing the second side surface from the first side surface, the second side surface opposing the first side surface;

generating scan data from the scanning of the model;

creating a virtual three-dimensional image of the patient's dental conditions with the scan data;

determining the first characteristic and the second characteristic of the dental implant analog to gather information for manufacturing the custom-abutment;

developing custom-abutment dimensional information based on the virtual three-dimensional image and the information gathered; and

fabricating the custom-abutment utilizing the custom-abutment dimensional information.

20. The method of claim 19 , further including, prior to the scanning, (i) taking an impression of the patient's dental conditions and (ii) preparing the model based on the impression.

21. The method of claim 20 , further including, prior to the scanning, attaching the scanning member to the dental implant analog.

22. The method of claim 19 , wherein the head portion is configured to be scannable via a mechanical contact scanner and via an optical scanner to generate the scan data for use in determining the first characteristic and the second characteristic of the dental implant analog.
