摘要：
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 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.
