    摘要： The present application relates to an apparatus and method in the field of dentistry and in particular to optical tools for diagnosis and imaging. It is a problem of the prior art that the use of fibre optic components yield a bulky dental camera with poor resolution. It is an object of the present invention to provide an imaging device (55) for dental instruments comprising a chamber adapted to be secured to the head of a dental instrument and for receiving and removing an imaging device (1), the chamber also adapted for isolating said imaging device from said dental instrument without compromising sterility of the dental instrument, comprising an optical window (53). The imaging device is easily removable from the dental instrument and electronic image detection occurs at the instrument head.

    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 handpiece includes a head, a tubular chuck having an open-end axial bore for receiving the shank of a dental bur and a tubular bur tube having an outer surface and an axial bore therethrough for receiving the chuck therein. The bur tube has at least one inner raceway formed integrally along its outer surface. An outer race having an outer raceway is associated with the inner raceway. A plurality of ball bearings are mounted between the raceways. A rotor may be formed integrally with the outer surface of the bur tube.
