<P>PROBLEM TO BE SOLVED: To provide a material which quickly promotes reproduction of periodontal tissues, is decomposed as tissues are reproduced, and makes re-operation for removal unnecessary. <P>SOLUTION: The periodontal disease treatment material 1 includes large pores 2 which are formed into film shapes comprising biodegradable polymers and have an average pore diameter of 100 to 500 μm on one side in the thickness direction and small pores 4 with an average pore diameter of 0.1 to 5 μm on the other side in the thickness direction, the large pores 2 and the small pores 4 are mutually communicating. Thus, the gums and an alveolar bone are divided, intrusion of regenerated gums in the alveolar bone side is prevented to promote smooth regeneration of the alveolar bone, and a plenty of blood from the alveolar bone side is supplied for the gum side via the small pores 4 communicating with the large pores 2, so that regeneration of the gums is promoted. Then, the periodontal disease treatment material 1 comprising the biodegradable polymer is decomposed and disappears as time passes, so that the re-operation for removing the periodontal disease treatment material 1 after recovery is not necessary and a burden on a patient can be reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
