摘要： A dental treating apparatus according to the present invention includes: a hand piece; a head unit; a driving unit; a control unit; a load specifying unit; and a load comparing 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 load comparing unit compares a load detected and a reference load. During a normal rotation period until driving for rotating the cutting tool in the normal rotation direction by the driving unit satisfies a predetermined first condition, the control unit maintains a rotation direction of the cutting tool in the normal rotation direction, and when a result of comparison by the load comparing unit attains a predetermined result during the normal rotation period, the control unit controls the rotation direction to the reverse rotation direction.

摘要： A method, and handpiece for performing the method, for controlling a drive device for moving a root canal instrument having a drive shaft and at least one cutting edge for preparing a root canal, and at least one drive motor being operated by a control unit. The root canal instrument is moved in at least one reciprocal movement in a first direction of rotation over a predetermined first angle of rotation and subsequently in a second direction of rotation opposite to the first direction of rotation over a predetermined second angle of rotation. After the at least one reciprocal movement, the root canal instrument is rotated over at least one third angle of rotation.

摘要： In medical or dental handpiece having a treatment tool driven by means of a drive part via a transmission arrangement, the transmission arrangement contains at least two planetary transmission stages connected one after another, which each have a sun gear mounted on a drive shaft, a planetary gear carrier having a plurality of uniformly distributed planetary gears cooperating with the sun gear, and a hollow gear, fixed to a housing, surrounding the planetary gears, having an inner toothing, wherein the planetary gear carrier of at least one transmission stage serves as drive shaft and carrier of the sun gear of the following transmission stage. In order to increase the stability of the arrangement the drive shaft for each transmission stage is extended beyond the sun gear driven thereby and in that the planetary gear carrier belonging to this sun gear is arranged rotatably on the extension.

摘要： The invention relates to a control device for the drive of a dental handpiece operated with a regulated electric motor. So that a dentist has an acoustic feedback concerning the loading of a tooth worked with the dental handpiece, the control device is so configured that a speed of rotation characteristic dependent on the load of the electric motor, starting from an initial point, falls with increasing motor current or increasing power, wherein at least one of the initial point, the inclination, and the development of the falling characteristic is selectable.

摘要： A dental device for preparing a tooth for a crown and for preparing the crown and a method of use. The dental device includes a tooth-preparation portion and a crown-preparation portion. The tooth-preparation portion prepares the tooth for the crown, thereby forming a crown-prepared-tooth, and thereafter, takes measurements of the crown-prepared tooth, thereby forming crown-prepared-tooth measurements. The crown-preparation portion is operatively connected to the tooth-preparation portion and prepares the crown for the crown-prepared tooth based upon the crown-prepared-tooth measurements received from the tooth-preparation portion.
