An endodontic file system is provided for simultaneously cleaning and shaping multiple root canals, the system includes a drill head having a distal portion and a proximal portion; at least two adjustable couplers on the distal portion of the drill head, each adjustable coupler configured to secure an endodontic file for cleaning a root canal; and a rotary system configured to rotate each adjustable coupler, where at least one endodontic file has an adjustable working distance from the drill head to a root canal of a tooth. In an example, each adjustable coupler can be configured to have a torque control configured to allow for controlling the rotation of the adjustable coupler based on an amount of torque.

A multi-directional handpiece that includes a motor drive extending along and configured for rotation about a body axis, the motor drive having: a motor gearing at a proximal end of the motor drive; and a file gearing in engagement with the motor gearing for transferring the rotational and axial movement to a workpiece; and a housing for the workpiece; and wherein through rotation of the motor drive, the workpiece moves in an axial oscillating motion while being rotated.

The invention provides a unitary cordless dental drive apparatus with a cantilever arm extending outward and positioned to allow a dental nose cone to be connected. An activating switch is located at the free end of the cantilever arm in a position that is convenient for manipulation by a user. In a second embodiment, the switch is in the form of a contactor mounted below the cantilever arm to contact the nose cone when pressed. In a third embodiment, a foot pedal connected to a wireless transmitter is provided to send a signal to a receiver located within the handpiece for activating the handpiece.

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.

A dental device is disclosed comprising a dental handpiece, a controller including a microcontroller and a foot control pressure sensor, and a foot pedal. The foot pedal is in communication with the controller and controls the dental handpiece. The dental device is arranged to configure between at least two of a speed limiting mode, a feathering mode, and a standard mode. In the speed limiting mode, the controller proportions air flow so as to limit the speed of the dental handpiece to a specified speed. In the feathering mode, the foot pedal proportions air to the controller which then transmits the air to the dental handpiece such that the foot pedal controls the speed of the dental handpiece. In the standard mode, the speed of the dental handpiece is set without limiting by the controller and without feathering by the foot pedal.

Methods and systems for tracking a dental tool within an oral cavity for taking and/or updating of a dental impression are described. In some embodiments, a marker, optionally a magnetic marker, is coupled to position movements of a rotatable dental tool. In some embodiments, detected movements of the marker are used, optionally in combination with other tracking data, to map contours which a portion of the rotatable dental tool follows during interaction with a dental surface. Optionally, the interaction occurs during grinding, drilling, and/or other procedures; which may be preparatory, for example, to the manufacture and/or fitting of a dental prosthetic.

Various devices, assemblies, components, systems, and methods are provided relating to a delivery system, a connection plate, and an electrical connection system. An example delivery system may include a mount, a movement arm, a delivery portion, and a connection arm. The movement arm may be rotationally connected to the mount at a first connection point of the movement arm and may rotate relative to the mount about a first axis of rotation. The connection arm may be rotationally connected to the movement arm at a second connection point of the movement arm to rotate relative to the movement arm about a second axis of rotation. The movement arm and the connection arm may each be configured to be disposed at least a predetermined minimum height or greater above a ground level at a location of the second axis.

A universal controller for controlling dental devices includes a memory having a graphical user interface generator and control software for a plurality of dental devices. The universal controller includes a transceiver, a display for displaying graphical user interfaces and for receiving inputs, and an electronic processor connected to the memory, the transceiver, and the display. The electronic processor is configured to provide a graphical user interface to the display in response to a selection received from the display. The universal controller is configured to display a plurality of dental devices to be controlled and enable selection thereof. Further, multiple devices are displayable on the universal controller, along with a patient information.

Described herein is a dental handpiece for the endodontic treatment of a root canal, including a chuck for attaching and holding an endodontic file, an electric motor having a shaft for driving the endodontic file, and a control unit for controlling the motor, which receives a stream of input data. 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.
