1. A dental implant comprising:
- a coronal head portion and a non-threaded solid core attached to the coronal head portion, wherein the coronal head portion has a threaded exterior surface configured to engage a wall of a bone tunnel formed in a patient'"'"'s jaw;
a porous portion defining a bore that receives the solid core, the solid core being rotationally-locked relative to the porous portion within the bore; and
an apical anchor portion with an exterior threaded surface configured to engage the wall of the bone tunnel, wherein the apical anchor extends along only an apical section of the dental implant and defines a non-threaded bore that receives the solid core, the solid core being rotationally-locked relative to the apical anchor within its bore, wherein the bore of the porous portion defines a first opening at a first end of the porous portion and a second opening at a second end of the porous portion, and the solid core extends through the first opening and the second opening of the porous portion and into the bore of the apical anchor.

Abstract
An implant device has an exterior portion forming an exterior surface of the implant. The exterior portion is made of a porous material defining passages through the exterior portion. An inner portion has an outer surface with a treated area that is accessible from the exterior surface through the passages. The treated area has a treatment for direct attachment to bone or soft tissue.

9. A method of implanting a dental implant comprising:
-
forming a hole in a bone of a patient'"'"'s mouth, the hole being defined by an internal wall; and inserting the dental implant into the hole so that an apical portion and a porous portion of the implant engage the internal wall of the hole in the bone and affix the dental implant within the hole, wherein the implant comprises a coronal head portion and a non-threaded solid core and the porous portion defines a bore that receives the solid core, the solid core being rotationally-locked relative to the porous portion within the bore, and wherein the apical portion comprises an apical anchor extending along only an apical section of the dental implant, the apical anchor comprising a non-threaded bore that receives the solid core, the solid core being rotationally locked relative to the apical anchor within its bore. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A method of implanting a dental implant comprising:
-
forming a hole in a bone of a patient'"'"'s mouth, the hole being defined by an internal wall; inserting an apical threaded anchor of the dental implant into the hole so that the apical anchor fixably engages the internal wall of the hole in the bone and secures the dental implant in the hole, wherein the apical anchor defines a non-threaded bore and extends along only an apical section of the dental implant; inserting a porous portion of the implant into the hole so as to engage the internal wall of the hole in the bone, wherein the porous portion defines a bore; and inserting a coronal threaded head portion of the implant into the hole so as to engage the internal wall of the hole in the bone, wherein the implant comprises a non-threaded solid core that is received in the bores of the porous portion and the apical anchor, respectively, wherein the solid core is rotationally-locked relative to the porous portion and the apical anchor within their respective bores. - View Dependent Claims (20, 21, 22, 23)
