Abstract: An apparatus for the delivery of a biological composite and a method, kit, and system for preparing a biological composite is described herein. The biological composite includes both inorganic and biological materials.

Abstract: Bioactive substantially silica-free glass material with a hydroxyapatite layer thereon is described, as well as methods for producing hydroxyapatite on a borate glass.

Abstract: Novel kits are provided for the delivery of restorative compositions into an intraosseous space or surgical defect comprising cannulae for accessing an intraosseous space, mandarins insertable into the cannulae and movable therein, catheters and a system for the delivery of aliquots of restorative compositions into the space via the catheters.

Abstract: Novel methods for the delivery of biocompatible material to intraosseous spaces are provided comprising accessing a space, placing a first aliquot of restorative material into the space, and after a period of time sufficient for first aliquot to set, placing a second aliquot into the space.

Abstract: Uniformly sized and shaped particles of metal salts are provided comprised of one or more metal cations in combination with one or more simple oxoacid anions and a general method for the controlled precipitation of said metal salts from aqueous solutions. The methods proceed via the in situ homogeneous production of simple or complex oxoacid anions in which one or more of the nonmetallic elements e.g. Group 5B and 6B (chalcogenides), and 7B (halides) comprising the first oxoacid anion undergo oxidation to generate the precipitant anionic species along with concurrent reduction of the nonmetallic element of a second, dissimilar oxoacid anion. The oxoacid anions are initially present in solution with one or more metal cations known to form insoluble salts with the precipitant anion.
