Patent ID: 8002548

Claim:
A method of maxillary sinus bone grafting for placement of an implant, the method comprising: a first step of forming a vertical hole in a maxillary sinus floor of a maxillary sinus for placement of the implant; a second step of lifting a maxillary membrane via the vertical hole in the maxillary sinus floor; a third step of enlarging a diameter of the vertical hole with the maxillary membrane lifted; a fourth step of inserting the bone graft material via the enlarged vertical hole; a fifth step of pushing the inserted bone graft material in a space between the maxillary sinus floor and the maxillary membrane; and a sixth step of after the bone graft material has been cured, placing the implant into the vertical hole; wherein the second step includes a first sub-step of primarily lifting the maxillary membrane via the vertical hole of the maxillary sinus floor and a second sub-step of filling gel type bone graft material between the maxillary sinus floor and the maxillary membrane, which has been primarily lifted via the vertical hole of the maxillary sinus floor, so as to secondarily lift the maxillary membrane.
