A dental implant has threads with a long pitch so the implant can be driven into a predrilled hole in the bone by axially delivered blows. When rotational forces are placed on the implant in attaching or removing the prosthesis, the long pitch threads will mechanically resist the rotational forces. The implant also includes a post integrally formed thereon so a minimum of separate procedures is required. The post includes a screw having a nylon rod therethrough to lock the screw in place.
A dental implant device for mounting a prosthesis and minimizing the lodging of extraneous substances in interstitial spaces. A root form implant fixture is permanently implanted in a user's jaw bone. The fixture includes anchorage and engagement sections. The engagement section includes a cylindrical portion adjacent to the anchorage section, a beveled portion that is adjacent to and coaxially disposed with respect to the cylindrical portion and a hexagonal portion adjacent to and coaxially disposed with respect to the beveled portion.
A dental implant has a body with a press fit diameter fit into a hole drilled into a patient's jaw bone, and having a helical groove machined into the body diameter to improve the rate of growth of bone tissue thereinto to securely lock the implant in position. A shallow height oppositely wound helical thread may be added to increase the holding force upon initial fitting of the implant. The shallow height and long pitch of the thread produces only minimal stress of the surrounding bone tissue to insure long term retention.
This invention concerns a device for attaching fractured hip-joint heads. The device has an angular plate which includes a bone plate attachable to the femur and a sleeve extending at an angle from the bone plate. The device also includes an anchor bolt having a shaft insertable into the sleeve and a threaded part extending from the shaft and having a multi-pitch thread.
A dental retaining screw used to secure dental components, such as abutments, copings, and prosthesis to dental implants. The screw having a locking mechanism adapted to prevent the screw from loosening during shipping or while experiencing vibrations. The locking mechanism includes a locking component and biasing members located in the head portion of the retaining screw.
