    摘要： The present invention relates to an endodontic file clip (1) for an apex locator, comprising: a hollow body (2); a push button (3) movably linked to the body (2); a spring (4) pushing the push button (3) away from the body (2); an electrically conductive hook (5) movably arranged within the body (2) and partly protruding out of the tip (2a) of the body (2) and fixed to the push button (3) to securely attach an endodontic file (6) to the tip (2a) when the push button (3) is released towards the closed position, and disengage from the endodontic file (6) when the push button (3) is pressed towards the open position; characterized by further comprising: a detachment mechanism (7) for re-attachably detaching the push button (3), the spring (4) and the hook (5) from the body (2) for cleaning and disinfection in a dental washer disinfector.

    摘要： A stereo lithography apparatus (1) for generating a three-dimensional object (2), comprising: an optical unit (4) for projecting an image towards the photocurable substance (3) for hardening the photocurable substance (3) deposited in the focus layer (5); a control unit (6), characterized by further comprising: a detection unit (7) which comprises: a detection means (8) movably arranged in a detection region (9) for detecting during the generation process or in a generation-pause the image projected by the optical unit (4) and for outputting a detection signal; and a first driving means (10) for moving the detection means (8) into or out of the detection region (9), wherein the optical unit (4) comprises: a second driving means (11) linked to the optical unit (4) for moving the focus layer (5) into or out of the detection region (9), wherein the control unit (6) adjusts the optical unit (4) and/or modifies the image to be projected based on the signal indicative of the detected image.

    摘要： The invention relates to a 3D intraoral scanner which, with a single sensor (10) or a number of sensors that are rigidly connected to one another and a de-flection system (20), in particular as a mirror system or a prism system, simultaneously records spaced apart partial measurement volumes (MV1, MV2) as measurement data, and performs a correction using the measurement data of a previously calibrated overall measurement volume (MV) consisting of said individual partial measurement volumes (MV1, MV2).

    摘要： A method, system and a computer readable storage media for operating dental machines through an augmented reality control interface. A hands free interface may enable the control of a dental machine during dental treatment by using dexterous parts of the body other than the upper limbs (e.g. by using the lower limbs) on a first user/control interface to send instructions corresponding to a second user/ control interface that is different from the first user/control interface.
