Abstract: An implant system includes: an implant for implanting into a bone; an abutment to serve as a support for fixing a prosthesis to the bone; and a pivotal coupling between the implant and the abutment to permit, after the implant has been implanted into the bone, precise angulation in all directions of the abutment with respect to the implant before the abutment is fixed at the desired precise angulation with respect to the implant. Preferably, the pivotal coupling includes a ball-and-socket having complementary shaped contacting surfaces which are uneven to temporarily hold them in a direct pivoted position before permanently fixing them.

Abstract: A clamping device for clamping a rodlike member to a housing, particularly a dental tool to a handpiece, includes a tapered sleeve and a tapered collet received within the tapered sleeve, both having open ends for receiving the rodlike member. A depressible button is engageable with the closed end of the tapered collet to move the collet outwardly of the tapered sleeve, thereby to expand the tapered collet and to permit removal or insertion of the rodlike member. Several improved versions are also described including an annular seal carried by the open end of the tapered sleeve, a coiled spring urging the tapered collet inwardly of the tapered sleeve, an air bearing rotatably mounting an air turbine and the tapered sleeve, etc.

Abstract: A clamping device for clamping a member to a housing, includes a sleeve unit and a chuck unit having interengaging threads such that both units are rotatably and axially displaceable relative to each other. A spring normally urges one unit in one rotary direction relative to the other unit such that the sleeve unit contracts the open end of the chuck unit to a clamping position. A manual operator is effective, when operated, to produce a rotary displacement of one unit in the opposite rotary direction relative to the other unit, while restraining a rotary displacement of the other unit, such as to effect an axial displacement between the two units to permit the open end of the chuck unit to expand to a releasing position. Several embodiments are described in which the manual operator is a depressible push-button assembly. In one embodiment, depression of the push-button rotates the sleeve unit while rotation of the chuck unit is restrained, whereas in other described embodiments, depression of the push-button rotates the chuck unit while rotation of the sleeve unit is restrained.

Abstract: An extension device for dental handpieces for extending the effective length of a dental tool to be clamped within the dental handpiece. The extension device includes an extension unit including a shaft at one end to be clamped within the dental handpiece instead of a dental tool, and a sleeve having a radially-contractible section at the opposite end for receiving a dental tool; and a clamping unit applicable over the radially-contractible section of the sleeve, after having received a dental tool, for securely clamping the dental tool within the sleeve. Also described are a high-speed dental handpiece in which the extension device is particularly useful, and an arrangement for providing lateral support to the extension device when included in the dental handpiece.

Abstract: A clamping device for clamping a member to a housing includes a sleeve unit carried by the housing and having an open end formed with a tapered inner surface; and a chuck unit receivable within the open end of the sleeve unit, the chuck unit having an open end which is radially contractible for receiving and clamping the member. The chuck unit is movable axially in one direction to a clamping position, or in the opposite direction to a releasing position. The sleeve unit and chuck unit include interengaging elements such that rotation of the sleeve unit in opposite directions relative to the chuck unit moves the chuck unit to its clamping and releasing positions, respectively. A spring normally urges the sleeve unit to its clamping position. A manual operator rotates the sleeve unit in the opposite direction to move the chuck unit to its releasing position.
