The present invention relates to a membrane for implant, which is a pocket type. In the present invention, the storage space (50) for storing the artificial bone (4) is formed inside the membrane and porous holes (31) is formed at the rear portion (30) in contact with the alveolar bone, thereby facilitating the integration with and regeneration of the alveolar bone tissue in contact with the grafted artificial bone and preventing the deviation of the artificial bone during the procedure and the regeneration afterwards for effective implant.
