The present disclosure relates to orthopedic implants including a porous, non-metallic, bone interface or outer bone contacting surface adapted for promoting bone ingrowth into the pores of such surface. The present disclosure also relates to orthopedic implants having a porous, non-metallic and/or polymeric bone interface or outer bone contacting surface wherein the implant has a stiffness that approaches or substantially matches the stiffness of the surrounding bone and thereby reduces the effects of stress shielding. The present disclosure also relates to methods of making such implants.

Orthopedic implant with porous polymer bone contacting surface

Methods of forming polymeric articles using plasma treated polymer resins, and orthopedic implants comprising a polymeric article wherein the polymeric article has reactive groups bonded to polymer molecules in an interior region of the polymeric article.

Modified polymeric materials and methods of modifying polymeric materials

Dental implants made at least in part of a porous tantalum material for enhancing the osseointegration of the dental implant into surrounding bone. For example, there is provided a dental implant which includes a porous tantalum portion and an outer portion having a color generally replicating the color of natural teeth. The dental implant further comprises a core portion and the porous tantalum portion at least partially surrounds the core portion. An esthetic portion is disposed at least the outer portion and the porous tantalum portion is disposed for at least partially reinforcing the esthetic portion. After implantation of the implant, bone tissue may osseointegrate into the porous tantalum portion to anchor the implant in position within the surrounding bone. Other embodiments of implants are provided, each implant including at least a portion thereof formed of porous tantalum for improved osseointegration.
