A detection system for remotely determining the speed of a rotating tool tip in a pneumatic dental handpiece. A means for detecting the speed of the rotating tool tip monitors a periodic mechanical function at the pneumatic hose connected to the handpiece. The monitored periodic mechanical function serves to provide feedback that is used to control the speed of the rotating tool tip. The means for detecting the speed of the rotating tool detects a mechanical function of the rotating tool tip, which in transmitted to a controller. The controller in turn regulates the operation of an air supply valve in response to the detected mechanical function. The valve regulates the flow of air to the handpiece. By continuously adjusting the flow of air through the valve into the pneumatic hose, the speed of the rotating tool is maintained at the desired cutting speed. |

A dental handpiece has a head section, a neck section, a grip section connected to the grip section, and a drive unit connected to the grip section. The handpiece also has detent means for preventing relative rotation between the neck and grip sections. The detent means includes a detent pin arranged axially slidably in the grip section, spring means for biasing the pin proximally so that the distal end of the pin is arranged inside the grip section in a rest position, and catch means formed at the proximal end of the neck section for receiving the pin for engagement. When the drive unit is brought into connection to the grip section, the pin is pressed distally to project out of the grip section into engagement in the catch means, to thereby prevent relative rotation between the neck section and the grip section. |

The invention relates to an improved bur for use in handpieces having a rotatable chuck with a tool bore for receiving the bur, a friction grip member for frictionally retaining the bur in the chuck and a torque lock seat of non-circular cross-section and permitting length adjustment of the bur in the drive head by concentrically supporting the bur in the drive head at any position from a fully inserted position to a maximum retracted position. The bur includes a tool body having an axis of rotation, a working end for projecting from the handpiece and a driven end for insertion into the tool bore of the chuck. The driven end is a generally cylindrical shaft with a preselected outer circumference for fittingly engaging in the tool bore for concentric rotation of the driven end with the chuck. The shaft including a torque lock portion for fittingly and non-rotatably engaging the torque lock seat of the chuck. The torque lock portion has at least two flat surfaces circumferentially spaced apart by intermediate cylindrical mantle portions, for providing the locking portion with a cross-section including alternating circular and straight sections and fitting into the non-circular cross-section of the torque lock seat to prevent rotation of the torque lock portion in the torque lock seat. The circular sections have the same diameter as the outer diameter of the cylindrical shaft. A total area of the flat surfaces covers at least 0.001956 square inches and the circular sections extend over at least 30% of the outer circumference of the driven end. This maintains efficient torque transfer between the chuck and the tool and ensures concentricity of the bur in the handpiece to prevent undue vibration of the bur in the handpiece. |

An air-driven dental instrument (10) includes a replaceable vibrator module (16) detachably accommodated in an axial lodgment defined by an elongated outer casing (14) comprised of a frontal cap (22A) and a main body (26A) coupled with each other. When the cap (22A) is coupled, the module (16) is axially positioned against the cap (22A) by a positioning sleeve (90A) and is rotationally locked against the sleeve (90A) by a hexagonal formation (128) engaging into cutouts (136) formed on a housing (134). When the cap (22A) is disconnected from the main body (26A), the module (16) is retained by the housing (134) but is partly exposed therefrom. This permits a user to grip the module to thereby facilitate replacement of the module (16). |
