摘要： A bolder for a bit is disclosed. The bit may include a first locking element. The holder may include a housing; a base assembly including a first hole; a second locking element partially disposed within the first hole and configured to move between a locking position in which the second locking element engages the first locking element to prevent removal of the bit, and an unlocking position in which the second locking clement is spaced from the first locking clement allowing the bit to be removed; and a follower assembly contained within the housing and configured to move relative to the housing and base assembly between a first position in which the follower assembly supports the second locking element in the locking position, and a second position in which the follower assembly allows the second locking element to move from the locking position to the unlocking position.

摘要： A dental handpiece is disclosed including a turbine construction creating a radial in flow of air onto the impeller blades about the whole circumference of the turbine. This generates additional torque and avoids asymmetrical thrust on the impeller wheel. A pair of axially spaced air bearings support the turbine. Air supply to the bearings is controlled in such a way that the air bearings are floated before drive air is supplied to the turbine and after drive air to the turbine has been shut off. This ensures that the air bearings are always operational irrespective of the operational state of the turbine. The handpiece has an improved ergonomic shape, especially the shape and configuration of the front or drive head, which provides additional tooth clearance and a better field of view. An angled swivel connection to the umbilical cord is provided which reduces physical strain on the dentist's wrist. A self adjusting lock and key type torque connection between the dental burr and the chuck is provided which accommodates both conventional burrs and the burr of the lock and key arrangement.
