Abstract

A dental implant system includes an implant having a well and an abutment having a post shaped to be received in the tapered well. Both the implant and the abutment are made from a millable ceramic, and the abutment post and/or the implant well have grooves carved therein. In one embodiment, the implant and the abutment are joined one to the other with a retentive elastomeric product containing micro-bubbles and micro-spacers. The dental implant system may be produced using a computer-readable medium containing instructions for analyzing surface data and X-ray data, for developing contour data of the implant and of the abutment according to the anatomy of the patient, and for generating machine instruction for milling the implant and the abutment from blocks of the millable ceramic. The invention provides the dentist with total flexibility in determining the most appropriate contours of the implant system and in reducing inventory.

Claims

1. A method of manufacturing and delivering a dental implant system, the method comprising:

providing an implant system comprising,

an implant having an outer surface, an inner surface, and an upper surface annularly connecting the outer surface to the inner surface, the inner surface defining a well projecting from the upper surface into the implant, the implant being monolithic and made from a millable ceramic; and

an abutment having a post, a stump, and a collar, the post having a shape configured to engage the well while leaving a gap therebetween, the stump being configured to support a dental restoration, the collar extending outwardly from the abutment at a transition between the post and the stump and having a lower outer perimeter substantially equal to an outer perimeter of the upper surface of the implant, the abutment being made from the millable ceramic,

wherein at least one of,

one or more grooves are defined in a wall of the post of the abutment, or

one or more recesses are defined in a wall of the well of the implant;

disposing a retentive product over the post or the well, such to fill the gap and one or more of the one or more grooves or one or more recesses; and

coupling the post of the abutment with the well, the retentive product being selected to provide at least a mechanical lock between the implant and the abutment retaining the abutment in the well after placement by a dentist while allowing abutment removal by the dentist if necessary.

2. The method of claim 1, wherein disposing a retentive product comprises disposing a product comprising yeast-resistant silicone.

3. The method of claim 1, wherein disposing a retentive product comprises disposing a retentive elastomeric product.

4. The method of claim 3, wherein disposing a retentive product comprises disposing a retentive elastomeric product containing spacers, such as to provide a controlled distance between the well and the post.

5. The method of claim 4, wherein the spacers are of substantially equal diameter.

6. The method of claim 1, further comprising the step of providing a computer-readable medium carrying one or more sequences of instructions for manufacturing a dental implant system, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:

analyzing surface and X-ray data to produce a three-dimensional model of a jaw and a tooth of a patient;

developing contour data of the implant and of the abutment suited for an anatomy of the patient; and

producing machine instructions for milling the implant and the abutment from blocks of the millable ceramic.

7. The method of claim 1, wherein providing the implant system comprises providing the collar shaped to have an upper outer perimeter configured to match a transverse anatomical profile of a natural tooth.

8. The method of claim 7, further comprising the step of determining the upper outer perimeter of the collar from X-ray data.

9. The method of claim 1, wherein providing the implant system comprises providing the outer perimeter of the upper surface of the implant shaped to conform to a surrounding bony ridge of a jaw at the dentist'"'"'s discretion and the collar with a height determined at the dentist'"'"'s discretion to find optimal position in relation to gingival crest to improve cosmetic appearance.

10. The method of claim 1, wherein providing the implant system comprises providing the collar with a variable height.

11. The method of claim 1, wherein providing the implant system comprises providing at least one of,

the upper surface of the implant and a bottom surface of the collar, or

an upper surface of the collar and a margin of a dental restoration, shaped with matching curved surfaces.

12. The method of claim 1, wherein providing the implant system comprises providing the collar with a flaring lateral surface.

13. The method of claim 1, wherein providing the implant system comprises producing the implant and the abutment with the millable ceramic having a white or off-white color to achieve a desired cosmetic result.

14. The method of claim 3, wherein disposing a retentive elastomeric product comprises disposing a retentive elastomeric product containing micro-bubbles such to provide elasticity and compressibility within the gap.

15. The method of claim 1, wherein providing the implant system comprises providing a plurality of grooves in the wall of the post and a plurality of recesses in the wall of the well, and wherein a lowest groove in the wall of the post has no facing recess, such to decrease an amount of force required by the dentist to extract the post from the well.
