Zusammenfassung:	PURPOSE:A filler for lacuna after extraction of tooth, to be expected to have alleviating and remedy promoting effect on pain by packing the filler to the lacuna of tooth extraction, having water insolubility, improved organism adaptability, improved shape retention in wetting, obtained by using sponge consisting of chitin, a material absorbable in organisms. CONSTITUTION:A filler for lacuna of tooth extraction consisting of chitin sponge (especially sponge having >=90% pore ratio in dry state of sponge), for example, obtained by dissolving water-insoluble chitin in a solvent to give chitin dope, blending the dope with a water-soluble high polymer substance, coagulating the blend and eluting and removing the water-soluble high polymer substance. The chitin sponge is naturally released from the wound face and absorbed with an enzyme when embedded in organism. It can be used not only in the lacuna of tooth extraction but also any tissue deficient part.
