Abstract
A resorbable crosslinked form stable membrane containing a composite layer of collagen material and inorganic ceramic particles containing 1.5 to 3.5 weight parts of inorganic ceramic for 1 weight part of collagen material, sandwiched between two layers of elastic pretensed collagen material, wherein the elastic pretensed collagen material is collagen material that has been stretched such as to be in the linear/elastic region of the stress-strain curve, the collagen material comprising 50-100% (w/w) collagen and 0-50% (w/w) elastin.
