Patent ID: 7845945

Claim:
A dental implant for supporting a dental restoration in a jawbone, the dental implant comprising: a body extending along a longitudinal axis and having a coronal end and an apical end, the coronal end forming, in part, an abutment surface that extend generally transverse to the longitudinal axis of the dental implant and the apical end, in part, forming an annular surface that extends generally transverse to the longitudinal axis of the dental implant; an external surface extending between the abutment surface and the annular surface and generally facing away from the longitudinal axis of the dental implant at least a portion of the external surface including an external thread having a pitch; a first inner surface concentric with the external surface, the inner surface generally facing towards the longitudinal axis of the dental implant and joined to the annular surface along an inner circumference of the annular surface on the apical end of the dental implant, at least a portion of the inner surface including an internal thread having the pitch of the external thread; a second annular inner surface that is joined to the first inner surface along an outer circumference of the second inner surface and extends generally transverse to the longitudinal axis of the dental implant and faces in a generally apical direction; a third inner surface concentric with the external surface and joined to the second annular inner surface along an inner circumference of the second annular inner surface, the third inner surface generally facing away from the longitudinal axis of the dental implant, at least a portion of the third inner surface including a second external thread having the pitch of the external thread; and an apical surface that faces in a generally apical direction and is joined to the third inner surface along an outer circumference of the apical surface.
