Abstract

A dental implant system includes a base member that is adapted to be embedded within a patient'"'"'s jawbone at a treatment site. The base member has a generally flat top side defining an outer periphery, a bottom side, and a central opening. At least one recess is included in the top side for receiving an alignment pin. The system further includes an implant screw that has a head and a threaded end. The threaded end is adapted to pass through the central opening of the base member and into the patient'"'"'s jawbone. Also, the head is adapted to be seated within the central opening of the base member after the threaded end is screwed into the patient'"'"'s jawbone. The implant screw further includes a threaded opening in the head.

inserting an implant screw through the central opening, wherein the implant screw has a head with a tapered section and a threaded end, and wherein the implant screw is perpendicular to the flat top side of the base member; and

turning the implant screw to secure the threaded end within the jawbone and to seat the head of the implant screw within the tapered opening of the base member such that the entire bottom side of the base member is in contact with the bottom of the recess.

2. A method as in claim 1, wherein the top side of the base member is generally flush with the patient'"'"'s jawbone.

3. A method as in claim 1, further comprising placing an abutment onto the top side of the base member, wherein the top side of the base member further includes at least one recess and further comprising placing a locating pin in the recess and inserting the locating pin into a corresponding recess on the abutment when placing the abutment on the base member to ensure non-rotatable alignment of the abutment with the base member.

4. A method as in claim 3, wherein the implant screw includes a threaded hole and further comprising a capture screw, and inserting the capture screw through a central opening of the abutment and into the threaded hole.

5. A method as in claim 4, further comprising seating the implant screw into the jawbone using a tool to adequately engage the tapered section with the tapered opening of the base member.

6. A method as in claim 4, wherein the abutment includes a locating sleeve extending from the central opening of the abutment, and further comprising placing the locating sleeve into the central opening of the base member.

7. A method as in claim 1, further comprising placing a healing cover onto the base member and suturing the patient'"'"'s gum over the healing cover, wherein the healing cover extends to the outer perimeter of the base member.

8. A method as in claim 7, further comprising accessing the healing cover, removing the healing cover from the base member and placing a tissue contouring cap onto the base member using a screw that extends into the implant screw.

9. A method as in claim 8, further comprising removing the contouring cap and securing an abutment to the base using a capture screw that extends through the abutment and into the implant screw.

10. A method as in claim 9, further comprising attaching a crown to the abutment.

11. A method as in claim 1, wherein the bottom side of the base member is generally flat, wherein the central opening tapers inward from the top side to the bottom side with a constant taper, and wherein the base member has an outer periphery that tapers with a straight taper inward from the top side to the bottom side such that the top side is greater in surface area than the bottom side.

12. A method as in claim 1, wherein the treatment site is where a tooth previously existed, and wherein the base member is sized to be generally the same size as the removed tooth.

13. A method as in claim 1, wherein the outer periphery of the base member includes a coating or surface treatment to increase the surface area of the outer periphery to promote osseointegration.

14. A method as in claim 1, wherein two of the sides of the base member have a length in the range of about 7 mm to about 12 mm, wherein the opposing sides of the base member have a length in the range from about 5 mm to about 10 mm, and wherein the thickness of the base member is in the range from about 1 mm to about 4 mm.

15. A method for securing a dental implant system to a patient'"'"'s jawbone, the method comprising:

cutting a portion of the patient'"'"'s gum at a treatment site sufficient to expose the patient'"'"'s jawbone;

removing a portion of the patient'"'"'s jawbone at the treatment site to form a recess, wherein the recess includes a bottom;

drilling a generally cylindrical hole with a drill bit into the jawbone at the bottom of the recess, wherein the hole is generally centrally located in the bottom and generally perpendicular to the bottom;

positioning a base member at the treatment site such that the base member is embedded within the patient'"'"'s jawbone at the treatment site, wherein the base member has a generally flat top side defined by an outer perimeter, a bottom side and a tapered central opening;

inserting an implant screw through the central opening, wherein the implant screw has a head with a tapered section and a threaded end; and

turning the implant screw to secure the threaded end within the hole in the jawbone and to seat the head of the implant screw within the tapered opening of the base member such that the entire bottom side of the base member is in contact with the bottom of the recess, and wherein the implant screw is perpendicular to the flat top side of the base member;

placing an abutment onto the top surface of the base member, wherein the abutment includes at least one locating pin, wherein the top side of the base member further includes at least one recess, and further comprising placing the locating pin in the recess when placing the abutment on the base member to ensure non-rotatable alignment of the abutment with the base member.

16. A method for securing a dental implant system to a patient'"'"'s jawbone, the method comprising:

removing a portion of the patient'"'"'s gum at a treatment site sufficient to expose the patient'"'"'s jawbone;

removing a portion of the patient'"'"'s jawbone at the treatment site to form a recess;
