The present invention relates to the following: an elastic resorbable chemically crosslinked collagen sponge for promoting an increase in soft tissue volume in an oral region, comprising 60-96% (w/w) collagen and 4-40% (w) /w) Elastin, which is an open pore of at least 80% porosity with a median pore diameter between 50 μm and 90 μm and a pore diameter greater than 10 μm, measured by mercury intrusion, from 45 ° C to 57 ° C The initial temperature and the density of the dry state of 50 mg/cm3 to 65 mg/cm3; the method for preparing the elastic resorbable chemically crosslinked collagen sponge, and the elastic resorbable chemically crosslinked collagen sponge The value of the oral cavity is used for the purpose of increasing the volume of soft tissue. |
