    摘要： Method for controlling an endodontic instrument, wherein an endodontic file (11) mounted on an assembly micromotor (8)-contra angle (9) is rotated in a first direction (working angle, δ) and successively in the opposed direction (unloading angle, η) with an alternated movement.
    According to the invention the working angle in said first direction gets smaller when a predetermined torque value is reached, originated by the engagement of said file (11) in a root canal (2), and the working angle in the first direction goes back to its original width when the torque value generated by the engagement of said endodontic file (11) in root canal (2) goes under a pre-determined value.
    System comprising a micromotor (8) and a contra angle (9) and an endodontic file (11) mounted in the said assembly of micromotor and contra angle;
    - a control unit of the micromotor for causing an alternated movement of an endodontic file (11) in which the file (11) is rotated in a first direction (working angle, δ) and successively in the opposed direction (unloading angle, η) with an alternated movement;
    - means measuring the torque value originated by the engagement of the file (11) in a root canal (2) being connected to the control unit, the control unit controlling the rotation of the motor such that the working angle in said first direction gets smaller when a predetermined torque value is reached, originated by the engagement of said file (11) in a root canal (2), while the working angle in the first direction goes back to its original width when the torque value generated by the engagement of said endodontic file (11) in root canal (2) goes under a pre-determined value.

    摘要： A method for controlling an endodontic instrument, wherein an endodontic file (11) mounted on an assembly micromotor (8)-contra angle (9) is rotated in a first direction (working angle, δ) and successively in the opposed direction (unloading angle, η) with an alternated movement.
    According to the invention, the inversion of the direction of rotation occurs with sinusoidal acceleration of the speed of rotation, from zero to the working value.
    System comprising a micromotor (8) and a contra angle (9) with alternated movement of an endodontic file (11) in a first direction (working angle, δ) and successively in the opposed direction (unloading angle, η) within an alternated movement, characterized in that it, comprises a control unit (60) of said micromotor rotation, generating a control signal of the acceleration of said micromotor with the shape of a sinusoid wave causing the inversion of the direction of rotation occurs with sinusoidal acceleration of the speed of rotation, from zero to the working value.

    摘要： A dental handpiece for the endodontic treatment of a root canal, comprising (i) a chuck for attaching and holding an endodontic file; (ii) an electric motor having a shaft for driving the endodontic file; (iii) a control unit for controlling the motor, which receives a stream of input data; characterized in that while monitoring the stream of input data, the control unit determines the current absorbed by the electric motor, and controls the motor so that the file alternates the direction of rotation at a frequency of from 1 to 20 Hz between a first direction and a second direction opposite to the first direction, and whereby the control unit controls the electric motor so that the file continuously rotates in the second direction when the monitored data fulfils a predetermined torque threshold condition during rotation in the first direction.

    摘要： An electrically safe treatment system for use in treating a patient includes two or more sections coupled with a joint that permits any one section to rotate relative to another coupled section. At least one of the sections includes an electrical component. An electrical contact associated with the joint is designed to maintain an electrical connection between a pair of sections throughout an angular range of motion of one of the sections relative to the other, coupled section. The electrical contact can also maintain a total resistance of a series connection including the two sections and the contact below a specified threshold. Alternatively, one or more insulator joints may be employed to meet safety requirements.
