An embodiment of the present invention, (A) melting and molding a synthetic polymer resin to prepare a base film; (B) preparing a first polymer film by pressing the base film; And (C) cross-laminating and bonding the first polymer film and the second polymer film comprising a natural polymer resin; including, and providing a method of manufacturing an alveolar bone regeneration shielding film that satisfies the following conditions. The average pore sizes of the base film and the first polymer film are D 1 and D 2 , respectively, and 0.1 ≤ D 2 /D 1 ≤ 0.5. |
