Description

Inlay-Platzhalter für genormte Inlays Inlay placeholders for standardized inlays
Die Erfindung betrifft einen Inlay-Platzhalter zum Vor¬ bereiten einer Kavität für die Aufnahme vorgefertigter Inlays.The invention relates to an inlay placeholder for preparing a cavity for receiving prefabricated inlays.
Aus der US 4 666 405 ist eine Vorrichtung beschrieben, bei der ein aus einem transparenten Material gefertig¬ ter Körper in eine mit lichtaushärtendem Material ge¬ füllten Kavität eingesetzt wird. Der Körper ist bei der bekannten Vorrichtung im wesentlichen kegelig ausgebil¬ det, nach Entfernen des Körpers wird der bei dem Aus¬ härten von diesem eingenommene Raum mit weiterem, in einem nächsten Arbeitsgang auszuhärtenden Material ge¬ füllt.From US 4,666,405 a device is described in which a body made of a transparent material is inserted into a cavity filled with light-curing material. In the known device, the body is essentially conical, after removal of the body the space occupied by it during the curing is filled with further material to be hardened in a next operation.
Für die Vorbereitung einer Kavität, in die aus der DE 37 43 433 Cl bekannte vorgefertigte Inlays eingesetzt werden können, ist die bekannte Vorrichtung nicht ge¬ eignet.The known device is not suitable for the preparation of a cavity into which prefabricated inlays known from DE 37 43 433 C1 can be inserted.
Der Erfindung liegt damit die Aufgabe zugrunde, einen Inlay-Platzhalter zu schaffen, die zur Vorbereitung ei¬ ner Kavität für die Aufnahme vorfertigter Inlays geeig¬ net ist. Erfindungsgemäß wird diese Aufgabe gelöst durch einen der Form des in die Kavität einzusetzenden Inlays ent¬ sprechenden Körper und einen an den Körper angesetzten, zur Handhabung dienenden, sich von dem Körper weg er¬ streckenden Schaft.The invention is therefore based on the object of creating an inlay placeholder which is suitable for preparing a cavity for receiving prefabricated inlays. According to the invention, this object is achieved by a body corresponding to the shape of the inlay to be inserted into the cavity and a shaft attached to the body and serving for handling and extending away from the body.
Weiter wird vorgeschlagen, daß Körper und Schaft aus einem transparenten Material gefertigt sind.It is also proposed that the body and shaft are made of a transparent material.
Eine spezielle Ausführungsform zeichnet sich dadurch aus, daß der Körper aus zwei zueinander beweglichen Elementen besteht, wobei ein die beiden Elemente vonei¬ nander weg drückendes Federmittel vorgesehen sein kann.A special embodiment is characterized in that the body consists of two mutually movable elements, wherein a spring means pushing the two elements away from one another can be provided.
Die Erfindung wird im. folgenden anhand von in der Zeichnung dargestellten Ausführungsbeispielen erläu¬ tert. Dabei zeigt:The invention is in. the following with reference to exemplary embodiments shown in the drawing. It shows:

Fig. 8 eine Fig. 7 entsprechende Darstellung bei einer gegen das Federmittel einander ange¬ näherten Elementen.FIG. 8 shows a representation corresponding to FIG. 7 in the case of elements which are brought closer together towards the spring means.
Der Inlay-Platzhalter zum Vorbereiten einer Kavität für die Aufnahme eines vorgefertigten Inlays besteht aus einem Körper 10 und einem Schaft 12. Der Körper 10 ent¬ spricht dabei in seiner Form dem Inlay, für' dessen Auf¬ nahme die Kavität vorbereitet werden soll, regelmäßig besteht der Körper aus einem den mittleren Raum der Ka¬ vität ausfüllenden Stegabschnitt und einem die Seiten¬ flächen der Kavität ausfüllenden Flanschabschnitt. Der Schaft 12 dient lediglich zur Handhabung des Körpers 10, also zu dessen Einsetzen in und Entnehmen aus der Kavität. Der im wesentlichen zylindrische Schaft 12 ist auf seiner von dem Körper 10 weg weisenden Stirnfläche mit einer Längsnut 14 versehen, an der die Ausrichtung der in die Kavität eingesetzten Vorrichtung erkannt werden kann. Bei Verwendung eines besonderen Bestecks dient diese Längsnut 14 auch zum Eingriff zwischen Be¬ steck und Vorrichtung.The inlay placeholder for preparing a cavity for receiving a prefabricated inlay consists of a body 10 and a shaft 12. The shape of the body 10 corresponds regularly to the inlay for which the cavity is to be prepared the body consists of a web section filling the middle space of the cavity and a flange section filling the side surfaces of the cavity. The shaft 12 is used only for handling the body 10, that is, for inserting it into and removing it from the cavity. The essentially cylindrical shaft 12 is provided on its end face facing away from the body 10 with a longitudinal groove 14, by means of which the orientation of the device inserted into the cavity can be recognized. When using a special cutlery, this longitudinal groove 14 also serves to engage between the cutlery and the device.
Bei dem in den Figuren 5 bis 7 dargestellten Auεfüh- rungsbeispiel besteht der Körper 10 aus zwei Elementen 10a und 10b, die zueinander beweglich sind und durch ein als Umlaufener Rahmen ausgebildetes Federmittel 16 voneinander weg gedrückt werden. Die beiden Elemente 10a, 10b sind dabei gleichartig unsymmetrisch ausgebil¬ det und um 180° zueinander verdreht angeordnet, wobei sie sich in der Bewegungsebene überlappen.In the exemplary embodiment shown in FIGS. 5 to 7, the body 10 consists of two elements 10a and 10b which are movable relative to one another and are pressed away from one another by a spring means 16 designed as a circumferential frame. The two elements 10a, 10b are similarly asymmetrical and are arranged rotated by 180 ° relative to one another, where they overlap in the plane of movement.
Bei der Verwendung wird in die vorbereitete Kavität zu¬ nächst ein Füllmaterial eingebracht und die Vorrichtung sodann in die Kavität eingebracht. Nach Abbinden - bei Verwendung eines lichtaushartenden Materials also nach Aufbringen von Licht durch den dann transparenten Kör¬ per der Vorrichtung - wird die Vorrichtung wieder ent¬ nommen. Nach Einbringen eines Fixationsmaterials (z. B. Zements) in den verbliebenen Raum wird das vorgefertig¬ te Inlay eingesetzt.When used, a filling material is first introduced into the prepared cavity and the device is then introduced into the cavity. After setting - when using a light-curing material, ie after applying light through the then transparent body of the device - the device is removed again. After a fixation material (eg cement) has been introduced into the remaining space, the prefabricated inlay is inserted.
Es versteht sich, daß der Körper 10 um die Schichtstär- ke des Fixationsmaterials kleiner als die vorgefertig¬ ten Inlays ausgebildet sein sollte.It goes without saying that the body 10 should be made smaller than the prefabricated inlays by the layer thickness of the fixation material.
Bei Verwendung der speziellen Vorrichtung nach den Fi¬ guren 5 bis 7 bewirkt das Federmittel 16, daß die Flan¬ sche der Elemente 10a, 10b sich kontaktbündig an die Nachbarflächen anlegen, so daß die an die Stelle der Elemente 10a, 10b einzusetzenden vorgefertigten Inlays esio-distal richtig positioniert sind. When using the special device according to FIGS. 5 to 7, the spring means 16 causes the flanges of the elements 10a, 10b to lie flush with the adjacent surfaces so that the prefabricated inlays to be used in place of the elements 10a, 10b esio -distally positioned correctly.
