Abstract
An implant fixture is built up of a titanium body, a titanium cover that is threadedly engaged with the body, a support having a columnar form of protuberance to be loosely fitted into a small hole in the head of the cover, and a connector spring member including a cylindrical body having spring action that enables it to take hold of the outer surface of the cover through a flange provided at one end. A forceps is built up of two frames, each provided at one end with a finger ring having a claw and at the other end with a holding surface for holding a second shaft of the support in parallel with the axial direction, and a guide rod which extends axially from one frame and has a slidable weight.
Claims2
An implant fixture forceps comprising:
- first and second frames pivotally joined to each other, each of said first and second frames having a first end which includes a finger ring and a second end which includes a holding surface having a semicircular shape in section, such that said holding surface can take hold of a shaft of an implant fixture support of an implant fixture in an axial direction for carrying the implant fixture;
- wherein:
- each of said finger rings is provided with claws which engage each other;
- and
- one of said first and second frames is provided with an axially extending guide rod connected at the first end of said one frame, said axially extending guide rod comprising two stoppers with a slidable weight located therebetween, which permits a press fitting of an implant fixture held by said holding surface into a cavity formed in a bone of a toothless gum by sliding said weight against one of said stoppers, wherein said implant fixture forceps can carry and press-fit the implant fixture in a continuous operation.
