| 110 | Artificial tooth root member and method of implanting same | US56240 | 1987-06-01 | US4762492A | 1988-08-09 | Noriyuki Nagai |
| A screw element is brought in thread engagement with a blade-shaped piece having a first threaded hole and open at sides, and the piece and the screw element are implanted together in a jawbone. A newly grown jawbone goes into osteobond with the implanted piece and screw element, the jawbone thus defining a second threaded hole. Subsequently the screw element is removed, and a pin neck portion is threadedly fitted into position in place of the screw element. The piece is small in size and open at sides. Therefore, it has no unfavorable effect on adjacent teeth and can be steadily implanted in a narrow jawbone structure. The pin neck portion is securely fixed by both the first threaded hole of the piece and the bone-defined second threaded hole, being thus steadily implanted in position. | ||||||
| 111 | Adjustable sinus lift implant | US868121 | 1986-05-28 | US4682951A | 1987-07-28 | Leonard I. Linkow |
| 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. | ||||||
