COLLAGEN SPONGE

摘要

- 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 μιτι and at least 80 % porosity with a pore diameter more than 10 μιη; an onset temperature of 45 to 57 °C and a density in dry state from 50 to 65 mg/cm3. -A process for preparing that resilient resorbable chemically crosslinked collagen sponge, and - That resilient resorbable chemically crosslinked collagen sponge for use as an implant in the oral cavity for soft tissue volume augmentation
