    Abstract: A plastic shank holding a metal dental anchor therein is disclosed, wherein the dental anchor is for anchoring a superstructure to a tooth. The dental anchor includes at least one threaded section and one manipulating end section joined together by a frangible portion so that the sections can be severed. The shank includes an opening for receiving the manipulating end section of the dental anchor in a force-fit connection therebetween, where the manipulating end section includes torque transferring wing portions for permitting the shank to pivot relative to the dental anchor when the dental anchor is being threaded into a channel in a tooth. A plastic hand driver is provided for receiving the shank therein, where the hand driver includes an abutment portion for rotating the shank, and projections for providing a snapped-in connection between the shank and the hand driver to permit a pivotal relationship therebetween while releasably retaining the shank within the hand driver.

    Abstract: A dental anchor is disclosed comprising an elongated member for anchoring a superstructure to a tooth. The elongated member includes at least one threaded section defining an anchoring portion that is attached to an L-shaped manipulating section by a reduced thickness portion in the form of an annular groove. The reduced thickness portion is frangible. The manipulating section is comprised of a cylindrical guide element that is coaxial with the anchoring portion and a torque transferring element having an axis that is substantially perpendicular to the axis of the guide element. The dental anchor is used with a dental attachment in the form of an elongated member having a first end that is adapted to be received by a power tool and a second end having a socket for receiving the manipulating section. Once the elongated dental anchor is inserted into a channel formed in the tooth, the manipulating section may be broken off at the frangible, reduced thickness portion without overstressing the tooth. Alternative embodiments provide second and third axially spaced apart reduced thickness portions, wherein the first reduced thickness frangible portion has a thickness greater than the thickness of the second frangible portion and, wherein the second reduced thickness frangible portion has a thickness greater than the third reduced thickness frangible portion. In the embodiments wherein multiple frangible portions are provided, each of the elongated anchoring portions are at least partially threaded and may be successively inserted into several channels formed in the tooth without reloading the dental tool.

    Abstract: A dental handpiece operable by compressed air having a turbine rotor, a drive sleeve for holding a dental instrument and coupled with the rotor by a ball-type planetary transmission, and an adjustment member operable on the planetary transmission so as to increase the torque transmissible by the planetary transmission. The transmission comprises inner and outer rings, with the balls frictionally engaged therebetween, the balls being in drive transmitting relationship with the rotor or the drive sleeve. A first of the rings is non-rotatable and a second of the rings is coupled with whichever of the rotor or drive sleeve is not associated with the balls. One of the rings is axially moveable relative to the other ring by the adjustment member in order to increase the radial load applied between the inner and outer rings through the intermediary of the balls whereby the torque transmitted by the planetary transmission can be increased. A pressure chamber is defined on one side of the adjustment member and receives a supply of compressed air in order to move the adjustment member with consequential axial movement of said one ring.

    Abstract: A dental anchor comprising an elongate member for anchoring a superstructure to a tooth. The elongate member includes at least two longitudinally spaced weakened portions which are defined by respective reduced thicknesses therein. Furthermore, the elongate member is provided with anchoring means or threaded portions spaced from one another by at least one of the weakened portions of reduced thickness. There is also provided a manipulating head which is spaced from one of the threaded portions by the other of the weakened portions of reduced thickness. The weakened portion of reduced thickness most remote from the manipulating head is of greater reduced thickness i.e., of lesser diameter than that of a weakened portion of reduced thickness most proximate the manipulating head. As a result, when the elongate member is inserted into a channel formed in the tooth, the threaded portion most remote from the manipulating head, severs automatically without overstressing the tooth thereby leaving the threaded portion most proximate the manipulating head in tact with the latter so that the latter threaded portion can be immediately inserted into a successive channel in the tooth without reloading the dental tool.
