Abstract: A hand tool (1) for separating a deep-drawn jaw-spanning dental apparatus such as an aligner or a bite splint of thermoform film. The hand tool includes a grip (2) for holding; a separating element (3) for thermally separating the deep-drawn thermoform film and refining the separated deep-drawn thermoform; a heating device adapted to regulate heating of the separating element (3) so as to increase the temperature of the thermoform film substantially to at least its glass temperature; and a power supply device for supplying electric power to the heating device.

Abstract: A sintering furnace for components made of a sintered material, in particular for dental components, having a furnace chamber having a chamber volume (VK). A heating device, a receiving space having a gross volume (VB) located in the chamber volume (VK) and delimited by the heating device, and a useful region having a useful volume (VN) located in the gross volume (VB), are disposed in the furnace chamber. The furnace chamber has an outer wall consisting of walls having a wall portion to be opened for introduction of a component to be sintered having an object volume (VO) into the receiving space. In the furnace chamber the heating device has a thermal radiator having a radiation field which is disposed on at least one side of the receiving space. At least the useful volume (NV) disposed in the receiving space is disposed in the radiation field of the radiator.

Abstract: A device for separating a deep-drawn jaw-spanning dental apparatus such as an aligner or a bite splint of thermoform film that includes: a separating element for thermally separating the deep-drawn thermoform film and simultaneously refining, the separated deep-drawn thermoform film; a heating means for regulating the heating of the separating element so as to increase the temperature of the thermoform film substantially to at least its glass temperature; a support for supporting the deep-drawn thermoform film relatively movable with respect to the separating element; a moving mechanism for moving the separating element along a separation contour of the deep-drawn jaw-spanning dental apparatus relative to the support; and a control unit adapted to control the heating means and the moving mechanism based on the separation contour.

Abstract: Disclosed herein is a dental device for delivering fluid continuously while activated in an endodontic application. The dental device includes a hollow needle having a tip end and a connector portion; and a handle. One end of the handle is configured to be affixed to the connector portion of the hollow needle. The opposite end of the handle is capable of being attached to an endodontic handpiece or a sonic agitator for the activation. The connector portion includes at least one tube connector that is an integral part of the connector portion of the hollow needle or a plurality of openings on the connector portion to accommodate the hollow needle to a connector. The connector is a modular fluid delivery connector which is removable from the needle such that it can be reused.

Abstract: A method and system to automate an administration and restoration generation process that includes forming a spline along a jaw, proposing potential interdental gaps, weighting the potential interdental gaps to obtain one or more delimiters, automatically proposing tooth number probabilities, and computing a best fit tooth number distribution to generate a patient specific restoration.

Abstract: An implant driver assembly for placing an implant according to a digital virtually planned implant and implant position in the jaw of a patient, wherein said implant driver assembly comprises at least an implant driver and at least a surgical template, wherein the implant driver having one or more first markers, and being adapted to be aligned with the surgical template, the surgical template having a guiding element and having one or more second markers, so that alignment of one or more first markers on the implant driver when connected to the implant and one or more second markers on the surgical template defines a spiral motion of the implant when it is being inserted in a jaw bone, the implant driver and surgical template also including at least one of the one or more first and at least one of the one or more second markers for indicating the implant driver's rotational or rotationally symmetric position as defined by the digital virtually planned implant position, whereby the guiding element is a bushing with a smooth bore; wherein the one or more first markers comprises a thread in or on an outer surface of the implant driver; wherein the one or more second markers comprises a thread follower for following the thread which is in or on the outer surface of the implant driver; wherein the thread follower comprises one or more pins that is/are removable or retractable from the guiding element of the surgical template.

Abstract: The invention relates to a method and an arrangement for the cleaning of a circumferentially closed canal by means of a light guide conducting a laser beam. The entry of the laser beam into the light guide is interrupted when the free end of the light guide is outside of the canal and/or the movement of the light guide within the canal is monitored and that if there is no movement or the movement is below a threshold value then a signal is triggered and/or the laser radiation is turned off or its output is reduced.

Abstract: The present invention is related to a curable composition for dental impression comprising: a curable base composition and a surfactant system comprising a first surfactant, which is at least one compound having formula (I) and a fluorotelomer having formula (II), which works synergistically with the fluorotelomer so as to permit the composition to surprisingly have a lower contact angle; these results are reached with relatively low concentrations of biodegradable surfactants.

Abstract: Described herein is a dental material applicator system comprising a segmented capsule and handpiece. The capsule separately holds a powder and a liquid such that upon activation in the handpiece by an operator, the powder and liquid are mixed into a paste. The operator then triggers the handpiece so that the mixed paste is extruded.
