ABSTRACT:
An oral implant, and method of using it, allow for the permanent installation of an artificial tooth in an area of the maxilla adjacent a descendent portion of the maxillary sinus. An opening is made in the maxilla to the Schneiderian membrane at the floor of the sinus. The implant has a basket or cradle which is filled with bone chips and inserted into the opening. A base attached to the cradle by an adjusting shaft is positioned in the opening after the cradle, e.g., in grooves at anterior and posterior portions of the opening. The shaft is then used to set the spacing between the cradle and the base such that the Schneiderian membrane is lifted and the sinus is reduced. After a period of time, new bone grows into the groove and about the bone chips so as to fuse the implant in place and thicken the maxilla in that area. Then a post is fastened to the implant and is used to support an artificial tooth structure.
