Abstract
Vorrichtung zur Befestigung eines für die Herstellung mindestens einer zahnmedizinischen Rekonstruktion vorgesehenen Rohlings an einer Halteeinrichtung einer für die Bearbeitung des Rohlings vorgesehenen Bearbeitungsmaschine, gekennzeichnet durch einen Körper mit einem ersten Abschnitt, der mindestens ein Haftmittel aufweist, durch das der Rohling am ersten Abschnitt fixierbar ist, und aus einem von der Bearbeitungsmaschine bearbeitbaren Material besteht, und mit einem zweiten Abschnitt, der zur Befestigung an der Halteeinrichtung der Bearbeitungsmaschine ausgebildet ist. Device for fastening a blank intended for the production of at least one dental reconstruction to a holding device of a processing machine provided for processing the blank, characterized by a body with a first section which has at least one adhesive by means of which the blank can be fixed to the first section, and consists of a material that can be processed by the processing machine, and with a second section that is designed for attachment to the holding device of the processing machine.
Description
Auf dem Gebiet der Dentaltechnik gibt es verschiedene Möglichkeiten einer maschinellen Bearbeitung keramischer, wachsartiger, kunststoffartiger oder metallischer Rohlinge oder Formkörper zur Herstellung einer Zahnrestauration, beispielsweise das CAD/CAM-Verfahren oder das Kopierfräsver-fahren, bei denen aus dem Formkörper die Restauration, beispielsweise eine Zahnkrone, ein Inlay, ein Onlay oder dergleichen, herausgeschliffen wird.In the field of dental technology, there are various possibilities for machining ceramic, wax-like, plastic-like or metallic blanks or moldings for producing a tooth restoration, for example the CAD / CAM method or the copy milling method, in which the restoration, for example one, is made from the molded body Tooth crown, an inlay, an onlay or the like is ground out.
Die Zahnrestaurationen müssen mit hoher Genauigkeit, also engen Fertigungstoleranzen, hergestellt werden. Dies erfordert eine Verbindung zwischen der Bearbeitungsmaschine und dem zu bearbeitenden Formkörper, welche die relative Position zwischen dem Formkörper und der Bearbeitungsmaschine innerhalb enger Toleranzen in einer fest vorgegebenen Position während des gesamten Bearbeitungsprozesses hält.The tooth restorations have to be manufactured with high accuracy, i.e. narrow manufacturing tolerances. This requires a connection between the processing machine and the molding to be machined, which maintains the relative position between the molding and the processing machine within tight tolerances in a fixed predetermined position during the entire machining process.
Es ist die Aufgabe der Erfindung, eine Vorrichtung zur Befestigung eines Rohlings oder Formkörpers in einen zugehörigen Halter für einen Formkörper zur Verfügung zu stellen, der eine maximale Formkörperverwertung durch optionales Nesting bis in die zur Einmal- und Mehrfachnutzung verwendbare Vorrichtung hinein ermöglicht.It is the object of the invention to provide a device for fastening a blank or shaped body in an associated holder for a shaped body, which enables maximum shaped body utilization through optional nesting down to the device that can be used for single and multiple use.
Diese Aufgabe wird mit einer Vorrichtung gemäß Anspruch 1 gelöst.This object is achieved with a device according to claim 1.
Bevorzugte Ausführungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments and developments of the invention are specified in the dependent claims.
Hierzu wird der Formkörper mit der Vorrichtung in Form eines Haftverbunds miteinander befestigt. Die Vorrichtung selbst ist aus einem Material, welches zusammen mit dem Formkörper maschinell so bearbeitet werden kann, dass der darunterliegende Anteil des Formkörpers gemäß vorgegebener CAM-/NC-Berechnungen herausgearbeitet werden kann.
