Abstract
A cranio-maxillofacial implant material that is made of a macroporous (greater than 100 microns in diameter) interconnecting porous polyethylene structure with bioactive glass particles dispersed throughout the porous polyethylene structure, is disclosed. The Implant provides augmentation or replacement of cranio-maxillofacial tissues when implanted subperiosteally or within cranio-maxillofacial soft tissue. The addition of the bioactive glass particles to the porous polyethylene implant structure provides for faster fibrovascular ingrowth into the implant material.
Claims19
A porous surgical implant material for replacing or augmenting tissue in the body comprising a composite material made of an interconnected omni-directional porous matrix structure comprised of synthetic resin and bioactive glass particles distributed throughout said matrix
- wherein said porous matrix structure is formed by sintering together a plurality of synthetic resin fines and wherein said bioactive glass particles remain separate and distinct and are not sintered together during said sintering process.
A porous surgical implant material for replacing or augmenting tissue in the body comprising a composite material made of an interconnected omni-directional porous matrix structure comprised of synthetic resin and bioactive glass particles distributed throughout said matrix and said matrix structure of said implant is formed in the absence of a poragenic material and wherein said porous matix is formed by the sintering of synthetic resin fines together.
