Abstract
(EN)
An embodiment of the present invention provides a method for manufacturing an alveolar bone regeneration membrane, the method comprising: (A) a step for preparing a base film by melting and molding a synthetic polymer resin; (B) a step for pressing the base film to prepare a first polymer film; and (C) a step for alternately laminating and bonding the first polymer film and a second polymer film containing a natural polymer resin. The method satisfies the conditions below. The average pore size of the base film and the first polymer film are D1 and D2, respectively, and 0.1 ≤ D2/D1 ≤0.5.
