US 8,075,312 B2 · Dental implant with improved osseointegration features

Abstract

Dental implants made at least in part of a highly porous biomaterial such as porous tantalum for enhancing the osseointegration of the dental implant into surrounding bone. For example, there is provided a dental implant which includes a core formed of with a head portion having an abutment interface and a stem portion extending from the head portion. A porous tantalum sleeve is disposed about the stem portion and occupies a substantial portion of the implant/bone interface of the implant. After implantation of the implant, bone tissue may osseointegrate into the porous tantalum sleeve 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.

Dependent claims

A dental implant, comprising:

an elongated implant body having opposed coronal and apical ends;
an abutment connector having correspondingly opposed coronal and apical ends, the abutment connector including a recess for receiving the coronal end of the body at the apical end of the abutment connector, the apical end of the abutment connector defining a non-threaded press-fit connection between the abutment connector and the coronal end of the body, the abutment connector being adapted for connection to an abutment at its coronal end, the abutment connector further defining a core extending from its coronal end to its apical end;
both the implant body and abutment connector having correspondingly aligned bores configured for receiving a retaining screw;
wherein the implant body further comprises a plurality of reinforcing members embedded within the body.
