ABSTRACT:
A dental pin assembly including an elongated dental pin inserted within a magazine sleeve. The magazine sleeve is removably inserted into the distal end of a shank and locked in place. The shank in turn is driven by a handpiece or manual driver for rotation of the pin. The pin is a composite of a plurality of individual contiguous coaxial pin sections, each pin section having a threaded stem and an enlarged head. Adjacent pin sections are separated by reduced diameter throat portions which are frangible to permit separation of one pin section from the next upon insertion of the one pin section into an aperture in a tooth stub. As one pin section is sheared off upon insertion, the next adjacent pin section is ejected from the adapter to place it in operative position for subsequent insertion into another aperture in the tooth stub. In this manner only one pin section projects at a time and all of the throat portions can be of identical diameter.
