Claim:
1. A device including a cannula, an expandable inflatable container and a filling material for displacing the Schneiderian membrane from the floor of the maxillary sinus in the process of dental implant surgery to treat normal human patients in need for enlargement of the height of the human maxillary alveolar ridge to enable the insertion of a conventional screwed dental implant for normal human patients, said device comprising: a cannula sized for insertion through an opening in said human maxillary alveolar ridge towards said Schneiderian membrane while said opening being sized so said conventional screwed dental implant will engage all the bony walls of said opening, said device further includes an expandable inflatable container, connector and an extension tube, at least part of said container being inside said cannula, said connector comprising a proximal portion and a distal portion, said distal portion includes a distal tube, said distal tube of said connector being inserted through the proximal end of said cannula inside said cannula and being fixated to said cannula so said distal tube of said connector being together with said at least part of said container inside said cannula, a proximal portion of said cannula includes inner screw threads, said distal portion of said connector includes outer screw threads, at least part of said distal portion of said connector threadably receivable in said proximal portion of said cannula, at least part of said container being located inside a distal portion of said cannula, said proximal portion of said connector being connected to said extension tube, said extension tube being connected to an injecting element including a filling material, so when said injecting element is activated said filling material is advanced through said extension tube and said distal tube of said connector inside said cannula to advance at least part of said container from inside said cannula distally to the distal end of said cannula, said filling material being advanced into said container to expand said container distally to said distal end of said cannula in several directions including also along the proximal-distal axis so the length of said container along the proximal-distal axis being also enlarged to displace said Schneiderian membrane.
