Abstract

The present invention provides a mid-gingival dental implant system that includes a dental implant having a threaded body portion and a superstructure extending from a coronal surface of the threaded body portion. The superstructure includes two O-ring housings for housing deformable O-rings. The mid-gingival system can also include two screws. One for screw retained final components and one for cement retained final components.

Claims

1. A dental implant system, comprising:

a dental implant including;

a body portion extending from a coronal end to an apical end, the body portion including a thread;

a superstructure extending from the coronal end of the body portion, the superstructure including;

a coronal O-ring housing;

an apical O-ring housing; and

a body portion positioned between the coronal O-ring housing and the apical O-ring housing, the body portion including at least one flat surface.

2. The dental implant system of claim 1, further including:

a first O-ring configured to be mounted within the coronal O-ring housing; and

a second O-ring configured to be mounted within the apical O-ring housing.

3. The dental implant system of claim 1, wherein the dental implant includes a threaded bore extending from a coronal surface of the surface structure toward the apical end of the body portion.

4. The dental implant system of claim 1, wherein the superstructure extends from a coronal surface of the body portion.

5. The dental implant system of claim 1, wherein a stop surface is formed between an edge of the coronal surface and the superstructure, the stop surface configured to engage an apical end of the final prosthesis.

6. The dental implant system of claim 5, wherein the final prosthesis is a crown.

7. The dental implant system of claim 1, wherein at least a surface of the superstructure is roughened via acid-etching.

8. The dental implant system of claim 1, wherein the body portion of the superstructure includes two flat surfaces.

9. The dental implant system of claim 8, wherein the two flat surfaces are diametrically opposed to each other.

10. The dental implant system of claim 1, further including:

a retention screw configured to couple a final prosthesis to the dental implant, the retention screw having a head, a shank, and a threaded body configured to engage a threaded bore of the implant.

11. The dental implant system of claim 10, further including:

a short screw configured to plug a threaded bore of the implant when securing a final prosthesis to the dental implant via cement.

12. The dental implant system of claim 11, wherein the short screw has a length that is less than a length of the retention screw.

13. The dental implant system of claim 11, further including:

a dental implant analog corresponding to the dental implant; and

an indicator tube, the indicator tube having one opening at the coronal end, a plurality of perforations extending from an apical end toward the coronal end, and a plurality of graduated marks, wherein the indicator tube and the dental implant analog can be used to confirm a proper seating of a final prosthesis before coupling the final prosthesis to a patient.

14. A dental implant system, comprising:

a dental implant including;

a threaded body portion; and

a superstructure extending from the body portion, the superstructure including two O-ring housing spaced apart by a body portion including two flat surfaces.

15. The dental implant system of claim 14, further including:

a first O-ring configured to be mounted within a first O-ring housing of the two O-ring housings; and

a second O-ring configured to be mounted within a second O-ring housing of the two O-ring housings.

16. The dental implant system of claim 14, further including:

a first screw configured to be used to couple a final prosthesis to the dental implant; and

a second screw configured to be used when a final prosthesis is coupled to the dental implant via cement, wherein one or more dimensions of the first screw are different form the second screw.

17. The dental implant system of claim 14, further including:

a dental implant analog corresponding to the dental implant; and

an indicator tube, the indicator tube having one opening at the coronal end, a plurality of perforations extending from an apical end toward the coronal end, and a plurality of graduated marks, wherein the indicator tube and the dental implant analog can be used to confirm a proper seating of a final prosthesis before coupling the final prosthesis to a patient.

18. A method of developing a final prosthesis, the method including:

installing a dental implant into a jawbone of a patient, the dental implant including;

a threaded body portion; and

a superstructure extending from the body portion, the superstructure including two O-ring housing spaced apart by a body portion including two flat surfaces, wherein the threaded body portion is positioned within bone and the superstructure is positioned beneath a top gingival surface;

attaching a healing abutment to the dental implant, the healing abutment including information that allows identification of at least two characteristics of the dental implant;

creating a three-dimensional computer model from a scan of at least a portion of the mouth including the healing abutment;

based on the information from the healing abutment, modifying the three-dimensional computer model so as to include a three-dimensional computer model of at least a portion of the dental implant to be used in creating the prosthesis; and

designing a three-dimensional computer model of the prosthesis form the modified three-dimensional model.

19. The method of claim 18, wherein the portion of the three-dimensional computer model of at least the portion of the dental implant includes the superstructure and a coronal surface of the threaded body portion.

20. The method of claim 18, further including:

transmitting at least a portion of the designed three-dimensional computer model of the prosthesis to a milling machine capable of producing at least a portion of the prosthesis.
