Porous implant device with improved core

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.

What is claimed is: 
     
         1 . An implant device comprising:
 an exterior portion formed from a porous material and defining an exterior surface including passages extending into the exterior portion;   a core forming an interior portion to which the exterior portion is coupled, wherein together the exterior portion and core form a transgingival flared coronal end portion of the implant device; and   a threaded endosseous portion extending apical of the flared coronal end portion.   
     
     
         2 . The implant device of  claim 1 , wherein the exterior portion forms a full or partial ring about the core. 
     
     
         3 . The implant device of  claim 1 , wherein the porous material is configured for soft tissue ingrowth. 
     
     
         4 . The implant device of  claim 1 , wherein at least the exterior portion has a treated area, wherein the treated area has a treatment comprising at least a roughening of the exterior surface. 
     
     
         5 . The implant device of  claim 1 , wherein at least the exterior portion has a treated area, wherein the treated area has a treatment comprising at least coating the exterior surface with a bio-reactive material. 
     
     
         6 . The implant device of  claim 1 , wherein at least the exterior portion has a treated area, wherein the treated area has a treatment comprising at least one of:
 threads,   annular grooves,   surface recesses,   at least one bio-compatible coating, and   at least one porous coating.   
     
     
         7 . The implant device of  claim 1 , wherein at least the exterior portion has a treated area, wherein the treated area has a treatment for direct attachment to soft tissue. 
     
     
         8 . The implant device of  claim 1 , wherein at least the exterior portion has a first treated area, wherein the first treated area has a first treatment for direct attachment to soft tissue, wherein the threaded endosseous portion has a second treated area, wherein the second treated area has a second treatment for direct attachment to bone. 
     
     
         9 . The implant device of  claim 8 , further comprising a dental abutment configured to mount to the implant device, wherein the dental abutment has a core and an exterior portion mounted to the core, wherein at least the exterior portion of the dental abutment has a treated area, wherein the treated area has a treatment for direct attachment to soft tissue. 
     
     
         10 . A dental abutment comprising:
 an exterior portion formed from a porous material and defining an exterior surface including passages extending into the exterior portion; and   a core forming an interior portion to which the exterior portion is coupled, wherein at least the exterior surface of the dental abutment has a treated area, wherein the treated area has a treatment for direct attachment to soft tissue.   
     
     
         11 . The dental abutment of  claim 10 , wherein the exterior portion forms a full or partial ring about the core. 
     
     
         12 . The dental abutment of  claim 10 , wherein the porous material is configured for soft tissue ingrowth. 
     
     
         13 . The dental abutment of  claim 10 , wherein the treated area has a treatment comprising at least a roughening of the exterior surface. 
     
     
         14 . The dental abutment of  claim 10 , wherein the treated area has a treatment comprising at least coating the exterior surface with a bio-reactive material. 
     
     
         15 . The dental abutment of  claim 10 , wherein the treated area has a treatment comprising at least one of:
 threads,   annular grooves,   surface recesses,   at least one bio-compatible coating, and   at least one porous coating.   
     
     
         16 . The dental abutment of  claim 10 , wherein the treated area has a treatment for direct attachment to soft tissue. 
     
     
         17 . The dental abutment of  claim 10 , wherein the first treated area has a first treatment for direct attachment to soft tissue, wherein the dental abutment has a second treated area, wherein the second treated area has a second treatment for direct attachment to bone. 
     
     
         18 . The dental abutment of  claim 10 , further comprising a dental implant configured to couple to the dental abutment, wherein the dental implant has a core and an exterior portion mounted to the core, wherein at least the exterior portion of the dental implant has a treated area, wherein the treated area has a treatment for direct attachment to bone. 
     
     
         19 . An implant device including a transgingival flared coronal end portion, the implant device comprising:
 an exterior portion formed out of porous material and including an exterior surface comprising passages extending throughout the exterior portion;   a core disposed within the exterior portion; and   a threaded endosseous portion extending apical of the flared coronal end portion.
