PROBLEM TO BE SOLVED: To prepare a dental absorptive tissue regenerating membrane which is capable of assuring its tight adhesion and the form retainability of the membrane according to application sites, is capable of imparting physical nature, such as, a wide range of decomposition time and hardness and is utilized for the purpose of tissue regeneration of the periodontium or bones or the like, in dental medical care fields of dental department, oral surgery, or the like. SOLUTION: This dental absorptive tissue regenerating membrane consists of a high-molecular blend combined with at least >=2 kinds of analogous polymers or heterologous polymers of different molecular weights selected from homopolymers or copolymers of L-lactic acid, DL-lactic acid, glycolic acid, ε-caprolactone and is formed to a porous sheet-like structure of 1 to 50 μm diameter in the size of pores, 5 to 95% porosity and 50 to 500 μm in thickness. The molecular weights of the homopolymers or copolymers of the L-lactic acid, DL-lactic acid, glycolic acid, ε-caprolactone are preferably 40,000 to 500,000. |
