摘要： A clamping structure is assembled in a handpiece (3). An embodiment of the clamping structure includes a connecting member for clamping a dental tool (5) and a controlling member (2). Two or more clamping portions (13) are disposed on the connecting member and a distance between the clamping portions (13) is changeable due to a control over the clamping portions (13). The controlling member corresponds to the connecting member and is abutted against the clamping portions (13). The controlling member (2) can be moved relative to the clamping portions (13) to form the control over the clamping portions (13) so as to allow the clamping portions (13) to clamp or to release the dental tool (5). A tungsten carbide coating layer is disposed on a contact surface of the controlling member (2), contact surfaces of the clamping portions (13), or both.

摘要： The present invention is directed to a dental mount for receiving and retaining a plurality of different dental ceramic blocks used in dental restoration treatments, wherein the dental mount comprises a substantially flat front face having a plurality of dental ceramic block receiving holes located thereon; each of the dental ceramic block receiving holes being dimensioned to form a retaining fit with any one of the different dental ceramic blocks. The advantage of providing a dental mount with dedicated holes for retaining any one of the dental ceramic blocks is that the dental mount can be used to comparatively present all the different types of dental ceramic blocks next to one another in an organized and graded manner so that a dentist may make quick and accurate comparisons between the different types of dental ceramic blocks. Furthermore, the dentist can quickly assess their stock levels by glancing at the dental mount. A further advantage is that the dental ceramic blocks are securely held apart from one another on the dental mount and therefore cannot damage one another when they are moved or transported.

摘要： The invention relates to an improved dental tool drive arrangement for a handpiece with a drive head, the tool drive arrangement permitting length adjustment of the tool in the drive head by concentrically supporting the tool in the drive head at any position from a fully inserted position to a maximum retracted position. The tool drive arrangement preferably includes a tool and a rotatable tool supporting element for concentrically supporting the tool from the fully inserted to the maximum retracted position, the tool preferably including a maximum retraction indicator for indicating to a user when the tool has been retracted to the maximum retraction position. This provides a significant advantage over the prior art by allowing a user to adjust the exposed length of a rotatable tool, preferably a dental bur, without exceeding safe operating limits. The invention also relates to an improved drive spindle which allows depth adjustment of a tool in a dental handpiece while maintaining efficient torque transfer and concentricity during high speed rotation.

摘要： A dental handpiece (1) to releasably retain a workpiece (e.g. a dental bur) (50) that is used to treat the teeth of a patient. The workpiece (1) is clamped within a hollow collet (4) between a pair of flexible clamping fingers (38) having a spring-like memory. A collet actuator (9) is arranged in spaced axial alignment with the collet (4). Both the collet (4) and collet actuator (9) are surrounded by a cylindrical spindle (14). An axial pushing force applied to a push-button (8) of the handpiece (1) causes the collet actuator (9) to slide through the spindle (14) towards the collet (4). A pair of wedge-shaped tips (32) having an angle of preferably 22 degrees are carried by the collet actuator (9) into the hollow collet (4) to stress the pair of flexible clamping fingers (38) thereof. Accordingly, the clamping fingers (38) are rotated outwardly and away from one another through a stroke gap (42) so as to be moved into contact with the spindle (14), whereby the workpiece (50) is released for removal from the collet (4).
摘要翻译：一种用于可释放地保持用于治疗患者牙齿的工件（例如牙科钻头）（50）的牙齿手柄（1）。工件（1）夹在具有弹簧状存储器的一对柔性夹紧指（38）之间的中空夹头（4）内。夹头致动器（9）以与夹头（4）间隔开的轴向对准地布置。夹头（4）和夹头致动器（9）都被圆柱形主轴（14）围绕。施加到手持件（1）的按钮（8）的轴向推力使得夹头致动器（9）朝着夹头（4）滑过主轴（14）。具有优选22度的角度的一对楔形尖端（32）由夹头致动器（9）承载到中空夹头（4）中以对其一对柔性夹紧指（38）施加应力。因此，夹持指（38）通过行程间隙（42）向外转动并远离彼此移动以与主轴（14）接触，由此工件（50）被释放以从夹头（4）。
