Abstract: A resilient resorbable chemically crosslinked collagen sponge for promoting soft tissue volume augmentation in the oral region, comprising 60-96% (w/w) collagen and 4-40% (w/w) elastin, which shows by mercury intrusion porosimetry interconnected pores with a median pore diameter between 50 and 90 ?m and at least 80% porosity with a pore diameter more than 10 ?m, an onset temperature of 45 to 57° C. and a density in dry state from 50 to 65 mg/cm3. A process for preparing a resilient resorbable chemically crosslinked collagen sponge. A method of using a resilient resorbable chemically crosslinked collagen sponge as an implant in the oral cavity for soft tissue volume augmentation.

Abstract: The invention provides: —A hydrophilic dehydrated partially purified bone replacement material of natural origin, wherein substantially all non-collagenous organic material is removed while inorganic, porous osseous structure and collagenous structure of natural bone are substantially preserved, characterized in that the bone replacement material contains 0.05 to 1.5 w/w % of at least one of a saccharide or a sugar alcohol, and 0.7 to 5.6 w/w % of a phosphate group selected from the group consisting of phosphate HPO42? and H2PO4?, this phosphate group being part of a physiologically acceptable salt and—a process for preparing a hydrophilic dehydrated partially purified bone replacement material.
