Abstract
Provided is a dental dual-structured membrane. The dental dual-structured membrane according to an embodiment of the present inventive concept includes a shielding portion for shielding a bone grafting material and an alveolar bone from the outside to prevent infiltration of other tissue cells, and an insertion and fixing portion connected to the shielding portion and inserted between a gum and the alveolar bone to fix the shielding portion, in which the insertion and fixing portion has a higher tensile strength than the shielding portion.
Claims16
A dental dual-structured membrane comprising:
- a shielding portion for shielding a bone grafting material and an alveolar bone from outside to prevent infiltration of other tissue cells;
- and
- an insertion and fixing portion connected to the shielding portion and inserted between a gum and the alveolar bone to fix the shielding portion,
- wherein the insertion and fixing portion has a higher tensile strength than the shielding portion.
A method for manufacturing a dental dual-structured membrane, the dental dual-structured membrane comprising a shielding portion in contact with a bone grafting material to prevent infiltration of other tissue cells toward a bone grafting material and an alveolar bone, and an insertion and fixing portion connected to the shielding portion, having a higher tensile strength than the shielding portion, and inserted between a gum and the alveolar bone to fix the shielding portion, the method comprising:
- a biodegradable polymer providing step of providing a biodegradable polymer;
- a molding material providing step of providing a molding material comprising the biodegradable polymer;
- a molding material input step of inputting the molding material into a sheet type mold to mold the molding material in a form of a sheet;
- a membrane sheet molding step of molding the molding material input into the sheet type mold in a membrane sheet by drying the molding material;
- and
- a membrane sheet compression step of compressing a part of the membrane sheet to provide the insertion and fixing portion having a reinforced tensile strength and the shielding portion that is the other part of the membrane sheet.
