| 摘要 |
The present invention relates to a medical barrier membrane, which is placed between the gums and an alveolar bone, for covering a bone grafting material grafted in the area of the missing alveolar bone or for regenerating attached gingiva, and more specifically, to a medical barrier membrane comprising: a punched portion in which fine pores allowing passage of blood are formed; and a sealing portion of which the entire surface is surrounded by the punched portion and is not provided with fine pores of any size, wherein the sealing portion prevents foreign substances introduced through an open sutured area on the gums that has been separated (for example, an area in the sutured area which has become separated) from entering a regenerated area on the alveolar bone, and prevents a grafted bone from dislocating, thereby improving generation efficiency of the alveolar bone. |
