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.

The present invention relates to a surgical dental tool for assisting with the implantation of a dental implant. The tool is designed to create an opening in a patient's jaw into which the dental implant will be inserted. In one embodiment, the tool includes a handle, a blade carrier, a pick and a blade stabilizing channel formed in at least a portion of the blade carrier and extends through at least a portion of the pick. The blade stabilizing channel receives and stabilizes a cutting blade. The blade carrier may include an adjustable clamping plate for removably securing the cutting blade in the blade stabilizing channel. The pick may include a sheath that receives and protects the tip of the cutting blade from breakage when the blade is in the blade stabilizing channel and is being used to cut a dental implant opening.

The present invention relates to a centering and guiding device (1) for a dental drill which comprises a body (10) including a guiding hole (15) for a dental drill and two arms (20, 30) pivotally coupled to the body (10). Each arm includes a respective free end (22, 32). Said arms (20,30) are capable of pivoting between a first open position, in which said respective free ends (22, 32) are mutually spaced apart to promote the movement of the device (1) from and towards an operating surface, and a second closed position, in which the free ends (22, 32) are approached to each other to match an operating surface. The device according to the invention also comprises an elastic element (40) to push the arms (20, 30) towards the closed position. According to the invention, each of said arms (20, 30) comprises a cylindrical end (27, 37), opposite to the corresponding free end (22, 32), accommodated in a corresponding seat (10A) defined by the body (10). Moreover, the cylindrical ends (27, 37) of said arms (20, 30) comprise respective toothed sectors (25, 35) mutually meshing each other to guide the rotation of said arms (20, 30) between said closed and open positions.

An endodontic file includes a handle and a bore formed entirely through the handle, and a fluted shank extending from the handle along an axis. A notch is formed in communication with the bore, and the notch is configured to open only in a direction along the axis to define an entrance to the bore only in a direction transverse to the axis.

Interproximal reduction guides apparatuses and methods of making and using them are described herein. These interproximal reduction guides apparatuses may include a body that fits over the patient's dental arch and one or more guide slots formed in them configured to limit the motion of an interproximal reduction cutting tool in a defined manner.
