The present invention relates generally to the field of bone graft substitutes and methods for making the same, particularly the invention relates to bone graft substitutes for use in dental or orthopaedic implants. The bone graft substitutes described herein comprise a silicate based material. The silicate based material is a silicate network with a porous structure. The silicate network has one or more metal cations incorporated therein. Preferably a phosphate is also incorporated into the silicate network. The bone graft substitute may have a low density, preferably a density of less than 1.1 g/cm.sup.3. The bone graft substitute may be an aerogel or a cryogel.

THERMOPLASTIC MATERIALS INCORPORATING BIOACTIVE INORGANIC ADDITIVES

Composite materials comprising thermoplastic polymeric material such as polyaryletherketones (PAEKs) and inorganic additive species serving to increase the processing and resultant mechanical, thermal, and biological properties of said thermoplastic polymeric material which may be subsequently used in various medical applications after the two materials are mixed through thermal processing methods. The inorganic additive species may be a calcium salt, and may include fluorine ions.

Compounds and matrices for use in bone growth and repair

Compositions of small molecules, matrices, and isolated cells including methods of preparation, and methods for differentiation, trans-differentiation, and proliferation of animal cells into the osteoblast blast cell lineage were described. Examples of osteogenic materials that were administered to cells or co-cultured with cells are represented by compounds of Formula II, IV, and VI independently or preferably in combination with a matrix to afford bone cells. Small molecule-stimulated cells were also combined with a matrix, placed with a cellular adhesive or material carrier and implanted to a site in an animal for bone repair. Matrix pretreated with compounds of Formula II, IV, and VI were also used to cause cells to migrate to the matrix that is of use for therapeutic purposes.
