Abstract

Provided is an implant receiving apparatus ( 10 ) comprising a core ( 20 ), the core defining a first end ( 30 ) and a second end ( 40 ), a wall ( 50 ) comprising inner surface ( 60 ) and outer surface ( 70 ) and a centerline ( 80 ) extending centrally of and between the ends ( 30, 40 ), the size and shape of the core ( 20 ) defining a socket or cavity ( 90 ) adapted to receiving an implant engaging member ( 100 ), wherein the wall comprises at least one threaded bore ( 110 ) for engaging a screw retainer, the bore traversing through the wall from the inner surface to the outer surface. Also provided is an implant engaging member, an implant system comprising both an implant engaging member and implant receiving apparatus as well as kits comprising an implant receiving apparatus.

What is claimed is: 
     
         1 . An implant receiving apparatus ( 10 ) comprising a core ( 20 ), the core defining a first end ( 30 ) and a second end ( 40 ), a wall ( 50 ) comprising inner surface ( 60 ) and outer surface ( 70 ) and a centerline ( 80 ) extending centrally of and between the ends ( 30 ,  40 ), the size and shape of the core ( 20 ) defining a socket or cavity ( 90 ) adapted to receiving an implant engaging member ( 100 ), wherein the wall comprises at least one threaded bore ( 110 ) for engaging a screw retainer, the bore traversing through the wall from the inner surface to the outer surface. 
     
     
         2 . The apparatus of  claim 1 , wherein the wall is cylindrical, multilateral, frustoconical, oval or lemniscate in shape. 
     
     
         3 . The apparatus of  claim 1 , wherein the wall comprises two or more threaded bores. 
     
     
         4 . The apparatus of  claim 3 , wherein the at least one threaded bore is positioned in a upper portion of the wall closer to the first end than the second end. 
     
     
         5 . The apparatus of  claim 1 , wherein the one or more threaded bores are positioned in the wall at an angle to permit a screw retainer to be threaded into the threaded bore along the axis thereof without interference from the wall or any other surface of the implant. 
     
     
         6 . The apparatus of  claim 1 , wherein the inner surface of the wall comprises a projection, the threaded core traversing through at least part of the projection. 
     
     
         7 . The apparatus of  claim 6 , wherein the surface of the projection comprises a groove allowing a screw head to be tightened flush with the projection surface. 
     
     
         8 . The apparatus of  claim 1 , wherein the outer surface of the wall comprises a plurality of steps, back-biting fins or extensions which resist removal of the apparatus during or after implantation. 
     
     
         9 . The implant receiving device of  claim 1  further comprising an implant engaging member attached thereto. 
     
     
         10 . The implant receiving apparatus of  claim 1 , further comprising one or more screws sized to threadedly engage the threaded bore. 
     
     
         11 . An implant receiving system comprising the implant receiving apparatus of  claim 1  and an implant engaging member. 
     
     
         12 . The implant receiving system of  claim 11 , further comprising one or more medical grade screws. 
     
     
         13 . An implant receiving apparatus ( 10 ) comprising a core ( 20 ), the core defined by a funnel ( 190 ) and a canal ( 200 ) extending from the centre of the funnel ( 190 ) and defined by a wall ( 50 ) comprising an inner surface ( 60 ) and an outer surface ( 70 ), a centerline ( 80 ) extending centrally of and between the funnel ( 190 ) and canal ( 200 ), the size and shape of the core ( 20 ) defining a cavity to receive an implant engaging member ( 100 ), wherein the wall comprises at least one threaded bore ( 110 ) for engaging a screw retainer, the bore traversing through the wall from the inner surface to the outer surface. 
     
     
         14 . The apparatus of  claim 13 , wherein the wall is cylindrical, multilateral, frustoconical, oval or lemniscate in shape. 
     
     
         15 . The apparatus of  claim 13 , wherein the wall comprises two or more threaded bores. 
     
     
         16 . The apparatus of  claim 13 , wherein the one or more threaded bores are positioned in the wall at an angle to permit a screw retainer to be threaded into the threaded bore along the axis thereof without interference from the wall or any other surface of the implant. 
     
     
         17 . The apparatus of  claim 13 , wherein the one or more threaded bores are positioned perpendicular to the wall. 
     
     
         18 . The apparatus of  claim 13 , wherein one of the one or more threaded bores is positioned parallel to the centerline and the other of the one or more threaded bores is positioned perpendicular to the wall. 
     
     
         19 . An implant receiving system comprising the implant receiving apparatus of  claim 13  and one or more of an implant engaging member. 
     
     
         20 . A kit comprising an implant receiving apparatus and one or more
 a) implant engaging members;   b) stints;   c) drill bits;   d) medical grade screws;   e) directions for implanting the implant receiving apparatus and/or the implant engaging member;   f) glue, cement, or any other component for affixing the implant engaging member to the implant receiving apparatus,   or any combination of a)-f).
