1. A method for displacing the Schneiderian membrane from the maxillary bone comprising:

  • a. Forming a path of insertion through the alveolar ridge of said maxillary bone towards said Schneiderian membrane;

    b. inserting through said path of insertion a hollow cannula, said cannula has a distal portion and a proximal portion, at least part of said distal portion of said cannula being inside said alveolar ridge, said proximal portion of said cannula being proximally to said alveolar ridge, said cannula being part of a device, said device further includes an expandable inflatable container, an extension tube and injecting element, said container has a proximal portion and a distal portion, said proximal portion of said container being located adjacent said distal portion of said cannula, said extension tube has a proximal portion and a distal portion, said proximal portion of said extension tube being located proximally to said said cannula, said proximal portion of said extension tube being connected to said injecting element;

    c. activating said injecting element to inflate through said extension tube said distal portion of said container so said distal portion of said container is expanded and advanced distally to the distal end of said cannula inside said maxillary bone to displace a segment of said Schneiderian membrane from a surface of said maxillary bone, said segment of said Schneiderian membrane was touching said surface before being displaced, at least part of said expanded distal portion of said container being between said displaced segment of said Schneiderian membrane and said surface, said surface is selected from the group consisting of the floor of the maxillary sinus and the floor of the nasal cavity.
