Claims
- 1. A system for anchoring a component within a body comprising a first member having a crestal end, a bore having a selected length along a longitudinal axis formed in the member through the crestal end, a second member comprising a post having a selected length dimensioned to be received in the bore of the first member, the bore having a self holding taper of a selected angle formed along a major portion of the length thereof, the post having a self holding taper of a matching angle formed along a major portion of the length thereof,a minor portion of the length of one of the bore and the post having a taper of a different angle to cause an interference fit to thereby provide a bacterial seal between the first and second members.
- 2. A system according to claim 1 in which the first member has a smooth surfaced shoulder extending from the bore at the crestal end with a narrow rim between the shoulder and the bore.
- 3. A system according to claim 2 in which the rim has a distal free end having a thickness of approximately 0.25 mm.
- 4. A system according to claim 1 in which the minor portion of the length of the bore and the post is approximately 1 mm in length.
- 5. A system according to claim 1 in which said minor portion of the length of the bore and post is located at the mouth of the bore.
- 6. A system according to claim 5 in which the angle of the taper of the minor portion is less than the angle of the taper of the major portion of the bore.
- 7. A system according to claim 6 in which the taper of the minor portion of the bore is negative with the diameter of the bore increasing in a direction going away from the crestal end and the taper of the minor portion of the bore is positive with the diameter of the bore decreasing in a direction going away from the crestal end.
- 8. A system according to claim 1 in which said minor portion of the length of one of the bore and the post is located on the post.
- 9. A system according to claim 8 in which the angle of the taper of the minor portion of the second member is greater than the angle of the taper of the major portion of the second member.
- 10. A system according to claim 1 in which the first member has an outer surface configuration which includes a plurality of outwardly extending fins to promote osseointegration with bone material of a living body when received in a recess formed in a bone of the living body.
