Abstract
The present invention relates to porous bone filling materials prepared by sintering bioactive glass fibers in order to achieve a three dimensional block with interconnecting porosity. Due to the osteoconductive properties the bioactive glass fibers, in block form are an ideal scaffold for new tissue (e.g. bone or cartilage) formation to occur. The manufacturing parameters can be adjusted to achieve porosities as high as 90 vol-%, or the manufacturing parameters can be adjusted to prepare strong porous blocks useful in load bearing application.
Claims49
A scaffold material comprising sintered glass or ceramic fibers and wherein the scaffold material is porous.
A scaffold comprising sintered glass fibers having a coating of one or more biocompatible polymers or copolymers.
34 The scaffold of claim 1 or 6 capable of promoting bone regeneration.
A method for making a scaffold comprising
- contacting glass or ceramic fibers together,
- sintering the glass or ceramic fibers in a manner to produce a porous scaffold.
A method of promoting growth of bone comprising
- contacting bone with a porous scaffold formed by sintering together glass fibers and
- allowing the bone to grow into the porous scaffold.
