Description

Derselbe Anmelder hat sich bereits mit der Modellübertragung mittels Gesichtsbogen mehrfach in Anmeldungen beschäftigt.The same applicant has already dealt with the Model transfer using facebow several times in Registrations busy.

All diesen Verfahren war jedoch die herkömmliche Art und Weise vergleichbar, daß eben der Übertragungsbogen als solcher mit der intraoralen Aufbißplatte über ein Verbindungselement zu einer Einheit fixiert wird, die letztlich geeignet seien soll, die am Patienten abgegriffene Situation in einen zahnärztlichen Artikulator zu übertragen.However, all of these methods were conventional and comparable way that the transfer sheet as such with the intraoral bite plate over one Connection element is fixed to a unit that should ultimately be suitable on the patient worn situation in a dental Transfer articulator.

Gerade beim Zuordnen und Fixieren von Bogen und Aufbißplatte zeigt sich jedoch in den meisten Fällen in der klinischen Situation, daß die Aufbißplatte zum Übertragungsbogen nicht in der exakt lagegerechten Position fixierbar ist.Especially when assigning and fixing sheets and Bite plate shows in most cases in the clinical situation that the bite plate for Transfer sheet not in the correct position Position is fixable.

Aus diesem Grunde wurde ein Übertragungsbogen kreiert und wird hier vorgestellt, der einerseits als Schnellübertragungsbogen die Seitenarme parallel zueinander verfahrbar und fixierbar macht, dessen Seitenarme ablesbar verlängerbar sind und der beidseits mit Ohroliven ausgestattet ist, die mit einer integrierbaren und bevorzugt höhenverstellbaren Gabellastütze oder einem Nasensteg eine gewünschte Ebene einstellbar macht.For this reason, a transfer sheet was created and is presented here, on the one hand as Quick transfer sheet parallel the side arms makes each other movable and fixable Side arms are extendable and readable on both sides is equipped with ear olives with a integrable and preferably height adjustable A desired fork rest or a nose bridge Level adjustable.

Als besonderes Merkmal gilt jedoch, daß die Aufbißplatte und der Bogen in der Phase der Patientensituation nicht miteinander verschraubt werden, so daß die angesprochene Verwindung entfällt. A special feature, however, is that the Bite plate and the bow in the phase of Patient situation not screwed together so that the torsion mentioned is eliminated.

Zu diesem Zweck enthält eine parallele Führung des anterioren Queranteiles des Bogens bevorzugt drei Paßbohrungen, die hier ein Dreieck bilden und zur Aufnahme von Nadeln geeignet sind, deren Passung so gewählt ist, daß sie ein reproduzierbares Anfahren von Punkten des extraoralen Teils der separaten Aufbißplatten erlauben.For this purpose, a parallel management of the anterior transverse portion of the arch preferably three Fitting holes that form a triangle here and to Needles are suitable, their fit so is chosen that it a reproducible start of Points of the extraoral part of the separate Allow bite plates.

Gleichzeitig sind die Nadeln längenmarkiert, so daß ans Labor, das einen eigenen Labor-Bogenmechanismus (statt Paßbohrungen ggf. Feingewinde) besitzt lediglich die Aufbißplatte mit ihren Markierungspunkten geschickt wird. Als Datentransfer wird gleichzeitig die Länge der jeweiligen Nadel bis zum Auftreffpunkt und die Länge der Seitarme durchgegeben. Laborseitig kann nun in Berücksichtigung des Winkels von Bezugsebene zur Kauebene die Aufbißplatte von der Rückseite perforiert werden, so daß die Möglichkeit besteht, mit zur Nadel abgestimmten Gewindestiften die Platte von der Ober- bzw. Unterseite mittels Muttern zu fixieren.At the same time, the needles are length-marked so that ans Laboratory, which has its own laboratory arch mechanism (instead Fitting bores, if applicable, fine thread) has only that Bite plate sent with its marking points becomes. The length of the respective needle to the point of impact and the length the side arms passed through. Laboratory can now in Consideration of the angle from the reference plane to the Chewable the bite plate perforated from the back be, so that there is the possibility with the needle the set screws from the top or to fix the underside with nuts.

Alternativ besteht die Möglichkeit, daß anstelle von Gewindestiften entsprechend dem Nadeldurchmesser Paßstifte verwendet werden, die mit Klemmechanismen von der Ober- bzw. Unterseite an der entsprechenden Position fixiert werden.Alternatively there is the possibility that instead of Grub screws according to the needle diameter Dowel pins are used with clamping mechanisms from the top or bottom of the corresponding Position to be fixed.

Durch die Wahl der Dreipunktabstützung gewinnen wir hiermit eine sichere Verbindung der Aufbißplatte mit dem Bogenmechanismus, wobei anschließend in gewohnter Art und Weise der Modelleinbau in den Artikulator erfolgt. By choosing the three-point support, we win hereby a secure connection of the bite plate with the bow mechanism, after which in the usual How the model is installed in the articulator he follows.

Die Erfindung wird nun anhand der Verfahrensansprüche 1-11 und der Bausatzansprüche 12-28 sowie der Fig. 1-4 näher erläutert. Dabei zeigtThe invention will now be explained in greater detail on the basis of method claims 1-11 and kit claims 12-28 and FIGS. 1-4. It shows

Fig. 1 schematisiert ein Profilbild eines Patienten mit angelegtem Gesichtsbogen, integrierter Aufbißplatte, Nadelmechanismus und Nasensteg, Fig. 1 is a schematic profile picture of a patient with an applied face bow, integrated bite plane, needle mechanism and the nose bridge,

Fig. 2 schematisiert eine mögliche Aufbißplatte, Fig. 2 schematically a possible bite plane,

Fig. 3 schematisiert eine möglich Fixation der Aufbißplatte mit dem Labor- Bogenmechanismus im Detail, Fig. 3 schematically a possible fixation of the bite plane with the laboratory sheet mechanism in detail,

Fig. 4 schematisiert eine Detailansicht des parallel verfahrbaren Übertragungsbogens im Detail. Fig. 4 schematically shows a detailed view of the parallel transfer sheet in detail.

Fig. 1 zeigt schematisiert eine Profilansicht eines möglichen Patienten mit angelegtem Gesichtsbogen (1), der hier mittels Ohroliven (3) und Nasensteg (2) so angelegt wurde, daß er durch die Glabellastütze (2) auf die Frankfurter Horizontale ausgerichtet ist. Diese ist bestimmt durch die beiden Unterränder der knöchernen Gehörausgänge und durch die beiden Unterränder der beiden Augenhöhlen. Fig. 1 shows schematically a profile view of a possible patient with an applied facebow ( 1 ), who was created here by means of ear olives ( 3 ) and nose bridge ( 2 ) so that it is aligned with the Frankfurt horizontal through the glabella support ( 2 ). This is determined by the two lower edges of the bony hearing exits and by the two lower edges of the two eye sockets.

Gleichzeitig soll mit (23) symbolisch dargestellt werden, wie die Nadeln (7) geführt (6) auf die Aufbißplatte (10) auftreffen, die im Bereich der Zahnreihen mit Aufbißmaterial (29) belegt ist.At the same time, ( 23 ) should symbolically show how the needles ( 7 ) guide ( 6 ) hit the bite plate ( 10 ), which is covered with bite material ( 29 ) in the area of the rows of teeth.

Fig. 2 zeigt schematisiert eine mögliche Aufbißplatte, die an der Trennlinie (30) extraoral (9) mit einer weichen Folie wie Polyethylen o. dgl. bevorzugt belegt ist. Gleichzeitig erkennen wir im gabelartigen Anteil des intraoralen Bereiches, partiell angedeutet, Perforationen (24) für das Aufbißmedium (29). Fig. 2 shows schematically a possible bite plate, which is preferably extraorally ( 9 ) covered with a soft film such as polyethylene or the like at the dividing line ( 30 ). At the same time, we recognize perforations ( 24 ) for the bite medium ( 29 ) in the fork-like part of the intraoral area, partially indicated.

Fig. 3 zeigt in schematisierter Anordnung die entsprechenden Laborschrauben bzw. -Nadeln (7′, 7′′). Die Platte (10) ist entsprechend einer rückseitigen Markierung von (11) perforiert (12) und wird auf ihrer Ober- bzw. Unterseite mit Muttern oder Klemmechanismen (12, 14) an drei Punkten starr fixiert und damit ebenso starr mit dem Bogen (1) verbunden. Fig. 3 shows a schematic arrangement of the corresponding laboratory screws or needles ( 7 ', 7 ''). The plate ( 10 ) is perforated ( 12 ) in accordance with a marking on the back of ( 11 ) and is rigidly fixed at its top or bottom with nuts or clamping mechanisms ( 12 , 14 ) at three points and thus also rigid with the bow ( 1 ) connected.

Fig. 4 zeigt mit linksseitigem Seitarm (18) in Detailansicht einen Übertragungsbogen (1, 26) zum symmetrischen, parallelen Verfahren der beiden Seitarme (18). Dabei sind die wesentlichen Elemente die beiden Plattenanteile (33, 34), sowie die Fortsätze (14), die jeweils in die andere Platte als Passung, d. h. Passung und Paßstift (14) eingreifen. Fig. 4 shows a left side arm ( 18 ) in a detailed view of a transfer sheet ( 1 , 26 ) for the symmetrical, parallel movement of the two side arms ( 18 ). The essential elements are the two plate parts ( 33 , 34 ) and the extensions ( 14 ), each of which engage in the other plate as a fit, ie fit and dowel pin ( 14 ).

Damit ist gewährleistet, daß die Elemente (33,34) symmetrisch zur Trennlinie (32) im geschlossenen Zustand auseinanderfahren. Um eine Fixation zu gewährleisten, ist in Führung (4) Plattenelement (16) eingelassen, das rechts und links der Trennlinie (32) einen Langschlitz (15) aufweist, in dem in geschlossenem Zustand die Paßstifte (22) in ihrer Endposition liegen und z. B. durch Mutter (17) fixierbar sind.This ensures that the elements ( 33, 34 ) move apart symmetrically to the dividing line ( 32 ) in the closed state. In order to ensure fixation, plate element ( 16 ) is inserted in the guide ( 4 ), which has a long slot ( 15 ) to the right and left of the dividing line ( 32 ), in which the dowel pins ( 22 ) are in their end position in the closed state and z . B. can be fixed by mother ( 17 ).

Nach Lösen dieser Mutter kann der Gesichtsbogen parallel und symmetrisch seitlich ausgefahren werden, wobei hier z. B. die vordere Paßbohrung (6) bzw. der hintere Nasensteg (2) mittig zum Gesamtbogen (1) verbleiben.After loosening this nut, the facebow can be extended parallel and symmetrically to the side. B. the front fitting hole ( 6 ) or the rear nose bridge ( 2 ) in the middle of the overall arch ( 1 ).

Gleichzeitig ist zu der vorderen Paßbohrung (6) distal jeweils eine Paßbohrung (6) angebracht, die damit ein Dreieck darstellen, durch das entsprechend paßgenau gearbeitete Nadeln (7) auf dem extraoralen Aufbißplattenanteil (9) Markierungen (11) setzen.At the same time, a fitting hole ( 6 ) is made distally to the front fitting hole ( 6 ), which thus represents a triangle, by means of which needles ( 7 ), which have been made to fit precisely, place markings ( 11 ) on the extra-oral bite plate portion ( 9 ).

Der Bogen selbst wiederum wird mit seinen Ohroliven (3) in die Gehörgänge des Patienten eingeführt, die Glabellastütze (2), die höhenverstellbar ist, erlaubt es, den Bogen (1) in die gewünschte Bezugsebene zu bringen, wobei es ggf. erforderlich ist, die Seitarme (18) ablesbar und bevorzugt symmetrisch zu verlängern (19) und zu fixieren (20). Damit soll erreicht werden, daß die Perforationen (6) so zu liegen kommen, daß die Nadeln (7) immer auf dem extraoralen Plattenteil (9) die entsprechenden Impressionen (11) liefern. The bow itself is inserted into the patient's ear canals with its ear tips ( 3 ), the glabella support ( 2 ), which is adjustable in height, allows the bow ( 1 ) to be brought into the desired reference plane, whereby it may be necessary the side arms ( 18 ) can be read and preferably extended symmetrically ( 19 ) and fixed ( 20 ). This is intended to ensure that the perforations ( 6 ) come to rest so that the needles ( 7 ) always provide the corresponding impressions ( 11 ) on the extraoral plate part ( 9 ).

Distal ist die Glabellastütze oder der Nasensteg (2) erkennbar und mit den Fixationsschrauben (28) wird der Querarm (5) des Bogens (1) mit den Seitarmen (18) montiert.The glabella support or the nose bridge ( 2 ) can be seen distally and the transverse arm ( 5 ) of the arch ( 1 ) with the side arms ( 18 ) is mounted with the fixation screws ( 28 ).

Es soll an dieser Stelle nicht unerwähnt bleiben, daß selbstredend auch die Möglichkeit besteht, die Seitarme (18) in einer definierten Länge zu konstruieren und daß im Gegenzug dazu die Aufbißplatte (10) im mittleren Bereich (25) in verschiedenen Größen zur Verfügung steht.It should not go unmentioned at this point that of course there is also the possibility of constructing the side arms ( 18 ) in a defined length and that in turn the bite plate ( 10 ) in the central region ( 25 ) is available in different sizes.
