Abstract
A novel dental implant with flexible expansion ribs that lock into and compress the bone within a drilled hole in the jawbone. Upon tightening the screw used to mount the implant abutment, a set of thin medical-alloy ribs lock into the surrounding bone to provide an immediate and permanently strong support for a dental prosthesis while bone growth into the implant occurs. The expanding ribs turn an edge outward to lock into the surround bone and preventing the rotation of the implant assembly during installation and use.
Claims7
A dental implant apparatus with expandable sides for locking into a predrilled hole in bone having an upper conformal socket, a hollow expansion tube with a wall having alternating ribs and open spaces, and a lower retaining nut;
- said hollow expansion tube compressible along a major axis by tightening a retaining compression screw through said conformal socket, said expansion tube and said retaining nut;
- and said ribs expanding outward upon the tightening of said retaining compression screw comprising said outwardly expanding ribs with a thinned portion on said ribs bowing outward to a greater distance that the thicker portion of said ribs to prevent rotation of said dental implant apparatus during installation and use, said thinned portions on said ribs alternating edges on alternate said ribs.
A dental implant apparatus with expandable sides for locking into a predrilled hole in bone having an upper conformal socket, a hollow expansion tube with a wall having alternating ribs and open spaces, and a lower retaining nut;
- said hollow expansion tube compressible along a major axis by tightening a retaining compression screw through said conformal socket, said expansion tube and said retaining nut;
- and said ribs expanding outward upon the tightening of said retaining compression screw, wherein said outwardly expanding ribs comprise a notched edge on said ribs bowing outward to a greater distance than the unnotched edge of side ribs to prevent rotation of said dental implant apparatus during installation and use, said notched edges on said ribs alternating edges of alternate said ribs.
