The present invention is a method for preparing a biomaterial scaffold material comprising: (a) providing a hydrogel comprising a fibrin network and a polysaccharide network; (b) subjecting the hydrogel of step a) to a freeze-thaw process. And (c) lyophilizing the physically crosslinked hydrogel obtained after performing step b). The present invention also provides a biomaterial scaffold material obtainable by this method, which is used to partially or fully increase, repair or replace the functional activity of the affected or damaged oral mucosa.
