摘要： A medical or dental fluid-driven handle with a control or regulation circuit for the control or regulation of the rotational speed of a rotary part to a predetermined rotational speed and methods are presented. The handle comprises a rotary part that can be set in rotary motion by a drive fluid, a fluid line carrying the drive fluid to or from the rotary part or a fluid branch line that is connected to a fluid line carrying the drive fluid, and a control or regulation circuit that is designed to control or regulate the rotational speed of the rotary part. An electrodynamic converter is driven by the rotary part for generating electrical energy. An actuator element is configured to act on the drive fluid and is electrically connected to the electrodynamic converter such that the actuator element is supplied with electrical energy generated by the electrodynamic converter.

摘要： A dental treating apparatus according to the present invention includes: a hand piece; a head unit; a driving unit; a resistor for load detection; a load comparing unit; and a control unit. The hand piece drivably holds a cutting tool on the head unit. The driving unit drives the cutting tool in a normal rotation direction or in a reverse rotation direction. The resistor for load detection detects a load applied to the cutting tool. The load comparing unit compares the detected load and a reference load each time driving for rotating the cutting tool in the reverse rotation direction by a predetermined rotation angle is performed. The control unit controls the driving unit based on a result of comparison by the load comparing unit.

摘要： 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.

摘要： A dental tool displacement apparatus for use with a motorized power handle to displace a dental tool includes a tool holder having a receptacle for receiving the dental tool, and a drive arrangement. The drive arrangement defines a transmission from the motorized power handle to the tool holder such that the tool holder undergoes reciprocating motion parallel to the tool axis at a first frequency of oscillations per minute and rotates about the tool axis at a second frequency of rotations per minute. In some cases, the two types of motion are generated by an eccentric drive pin engaging an annular slot which has gear teeth along one side, thereby generating an angular rotation step of the tool holder during each reciprocating stroke. In some cases, the first frequency is at least one order of magnitude greater than the second frequency.

摘要： A system for driving an electric handpiece in response to a pneumatic control signal may provide for fast interchange of handpieces, self-calibration and wide dynamic range of operation with precise speed control. The system may be incorporated into virtually any dental treatment center using traditional pneumatic drive handpieces, and a conversion kit may facilitate such conversion. The system may provide not only for controlling the speed and torque of a tool coupled to an electric drive handpiece responsive to a pneumatic control signal, it may also provide for coupling cooling air and treatment media, such as air and/or water to the handpiece. Coupling of a handpiece to an operating base of the system, including coupling of media lines and electrical connections may be made with a simple press and twist action using quick connection structure.

摘要： An apical portion of a root canal is cleaned with an abrading portion of a file that has a taper that is greater than 0.20. Once the apical portion has been cleaned with an abrading portion that is greater than 0.20, such as 0.25, then an endodontic point, such as a gutta percha point can be easily received in the apical portion of the root canal to seal the apex. It is optimal to utilize a set of instruments. All of the instruments may have files with abrading portions that are greater than 0.25. However, only the larger files need have such abrading portions since they are the last to be used when cleaning the apical portion.
