Expandable bone implant
First Claim
Patent Images
1. A bone implant, comprising:
- a coronal member formed of a coronal member material and defining an apical end portion that slopes radially inward while extending apically; and
a porous member formed of a porous member material that is at least partially porous, the porous member being removably positionable on the apical end portion of the coronal member, such that moving the coronal member and the porous member toward each other longitudinally expands the porous member generally radially outward on the sloped apical end portion.

Abstract
An expendable bone implant has a first member with a coronal end portion configured for supporting a prosthesis. A second member is at least partially porous, engages the first member, and is configured to expand outwardly upon a longitudinal force being applied to at least one of the first and second members. This anchors the implant in bone before mastication forces are applied to the implant.

10. A bone implant comprising:
-
a body defining an apical end portion; and a porous member formed of a porous material, the porous member being removably positionable on the apical end portion of the body, such that moving the body and the porous member relative to each other expands the porous member generally radially outward, wherein the porous member comprises a cavity sized to receive the apical end portion, and the body is movably longitudinally within the cavity, the porous member being configured to expand generally radially outward when the body is moved longitudinally within the cavity. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
