The present invention measures the thickness of the maxillary gum and alveolar bone at the corresponding position where the implant is placed, and when the maxillary sinus lining is damaged in the step of forming the implant placement hole at the corresponding position where the implant is placed, the length corresponding to the thickness of the gum and alveolar bone Selecting a fixture for promoting maxillary sinus endometrial regeneration； (S10), and fastening and fixing the selected maxillary sinus lumen restoration promoting fixture to the formed implant placement hole； and (S20), after undergoing a regeneration period of the maxillary sinus lining, implant Separating the fixture that promotes the regeneration of the maxillary sinus, which is fastened to the implant, (S30), and filling the artificial bone powder by lifting the regenerated maxillary sinus lining by inserting a cyrus lift into the formed implant； (S40) , Reinforcing the thickness of the alveolar bone through the filled artificial bone powder and forming a reinforcement fixture on the reinforced artificial alveolar bone (S50), A step of restoring the function of a tooth by implanting an implant prosthesis in the reinforcing insert； relates to a fixture for promoting the regeneration of the maxillary sinus for the implant procedure consisting of (S60), and for this purpose, the fixation for promoting the regeneration of the maxillary sinus is formed on the gum. A head that is pressed and pressed around the implant placement hole； And, the insertion portion is extended linearly downward to the head； And, the tapered entry portion extending downward from the insertion portion to gradually decrease in diameter； And, on the outer peripheral surface of the entry portion The spiral blade is formed and gradually reduced in diameter to be fastened to the alveolar bone； And, the curved portion formed at the insertion end of the entry portion； And a cell culture membrane fixed to the curved portion and induci
