Offenbart ist eine Absaugvorrichtung (100) zum Absaugen von Staubpartikeln umfassend einen Hauptkörper (110) mit einem Absaugtunnel (112) aufweisend eine Ansaugöffnung und eine Ableitöffnung (130), wobei die im Betrieb vor der Ansaugöffnung auftretenden Staubpartikel aufnehmbar und durch den Absaugtunnel (112) aus der Ableitöffnung (130) ableitbar sind, eine Koppelungsvorrichtung (140) zum Befestigen des Hauptkörpers (110) an einem Bearbeitungsbereich, eine Lichtanordnung (200), zum Beleuchten des Bearbeitungsbereiches, wobei die Lichtanordnung einen Rahmen (210) aufweist, entlang dessen zumindest ein Lichtelement (220) angeordnet ist, das sich im Wesentlichen über den gesamten Rahmen (210) erstreckt, wobei der Rahmen (210) mittig eine Durchblicksöffnung (230) umschließt, wobei das Lichtelement (220) im Betrieb auf den Bearbeitungsbereich gerichtet ist, und eine elektrische Schaltung zum Aktivieren und Deaktivieren der Lichtanordnung (200), wobei der Rahmen (210) oben einen Durchbruch (214) aufweist, der sich insbesondere über die gesamte Breite der Ansaugöffnung oder des Hauptkörpers (110) erstreckt.
摘要:
To provide processing methods for making dental devices with which a processing time can be reduced. A processing method for making a dental device including the steps of: carving an area having a predetermined shape out of a workpiece by cutting a groove along an area having the predetermined shape in the workpiece using a first processing tool, the groove having a processed width that is larger than a diameter of a bit of the first processing tool; and forming an object having a desired shape by performing a cut on the area having the predetermined shape using a second processing tool.
摘要:
A temporary anchoring device between cylinders and spacers of position keys for dental implants composed of cylinders (1) and spacers (2) equipped with means suitable for temporarily holding said cylinders (1) and the mentioned spacers (2) in their relative position, corresponding to that of the dental implant, in which said means consist of a first ring (4) destined for being engaged on the body of said cylinder (1), in addition to a second ring (5) which is engaged on a first spacer (2) of the position key and joined to the previous ring (4) by means of a bar (6). Compared to the systems used in the known art, the device of the invention offers the advantage of being pre-assembled on the spacer, by means of a simple and rapid operation effected outside the patient's mouth. The device of the invention is then also fixed to the respective cylinder situated in the oral cavity, with operations equally as rapid and simple, thus obtaining a temporary anchorage which holds the cylinders of the implant and the spacers forming the position key, in the relative correct position.
摘要:
A thermoplastic-based polymer adhesive for use in dentistry includes a thermoplastic polymer and an additional polymer or additive including at least one moiety, monomer, or prepolymer capable of changing at least one property of the thermoplastic-based polymer adhesive when exposed to an activation energy. The activation energy may be heat energy and/or sonic or ultrasonic energy. Bonding a dental component to a tooth includes placing the thermoplastic-based polymer adhesive between the dental component and the surface of the tooth and compressing the dental component against the adhesive, and, while compressing, applying an activation energy to cause crosslinking of the additional polymer or additive with the thermoplastic polymer.
