Die Erfindung bezieht sich auf eine herausnehmbare Zahnprothese, insbesondere in Form einer Transversalverbindung oder einer Brücke, eufweisend einen Prothesen- oder Brückenteil und einen Anker mit Klsmmern zum Hintergreifen der dem Prothesen- oder Brückenteil benechbsrten Zähne, wobei der Brückenteil gegebenenfalls mit sich in die unter sich gehenden Bereiche der benachbarten Zähne hineinerstreckenden Vorsprüngen bzw. die Klammern des Ankers sich in die unter sich gehenden Bereiche benachbarter Zähne erstrecken ausgebildet ist.The invention relates to a removable dental prosthesis, in particular in the form of a transversal connection or a bridge, comprising a prosthesis or bridge part and an anchor with clamps for engaging behind the teeth which are part of the prosthesis or bridge part, the bridge part possibly being in contact with one another protruding areas of the adjacent teeth or the brackets of the armature extend into the undercut areas of adjacent teeth.
Die Erfindung bezieht sich insbesondere auf eine mehr teilige Brücke eis Zahnersatz, aufweisend einen Erückenteil mit AufIsgerteilen, zur Auflage auf den dem Brückenteil benachoerter Zënnen und einen Brückenanker mit Klammern zum Hintergreifen der demBrückenteil benachbarten Zähne, wobei der Brückenteil gegebenenfalls mit sich in die unter sich gehenden Bereiche benachbarter Zähne hineinerstreckenden Vorsprüngen susgebildet ist.The invention particularly relates to one more Partial bridge ice dentures, comprising a back part with Aufgergerteile, for resting on the adjacent teeth of the bridge part and a bridge anchor with brackets for engaging behind the teeth adjacent to the bridge part, the bridge part possibly being formed with projections extending into the undercut areas of adjacent teeth.
Es ist eine mehrteilige Brücke als Zahnersatz bekannt, bei welcher die Brücke in einen lincuelen Teil und in einen labialen Teil unterteilt ist, beide Teile eine gemeinsame sich in mesio-disteler Richtung erstreckende Berührungsfläche, haben und beide Teile lesbar aneinender befestigt sind (G B6 06 621); Eine derartige Brücke kenn eingesetzt werden, ohne daß die benachbarten (gesunden) Zähne bearbeitet werden müssen, Auch ist es möglich, eine Brücke dieser Art einzusetzen, wenn die beiden benachbarten gesunden Zahne sogenannte unter sich gehende Bereiche aufweisen. Es ist jedoch nicht bekannt geworden, wie derartige Brücken eingesetzt werden sollen, ohne daß die Gefahr besteht, daß sich die beiden voneinander lösbaren Teile unbesbsichtigt lösen und die Gefahr des Verschluckens besteht.A multi-part bridge is known as a denture, in which the bridge is divided into a lincuelen part and a labial part, both parts have a common contact surface extending in the mesio-distal direction, and both parts are legibly attached to one another (G B6 06 621); Such a bridge can be used without having to work on the adjacent (healthy) teeth. It is also possible to use a bridge of this type if the two adjacent healthy teeth have so-called undercut areas. However, it has not become known how such bridges are to be used without there being a risk that the two parts which can be detached from one another will unintentionally come loose and there is a risk of swallowing.
Eine Brücke der vorgenannten Art ist weiterhin bekannt geworden (Zeitschrift "Neue Revue", Frühjahr 1987, Seite 94), bei welcher diejnehrteilige Brücke aus einem sogenannten Zwischenglied (dem Ersatz für den fehlenden Zahn) besteht und einem Klammerteil, welcher die beiden benachbarten gesunden Zehne umgreift und auch mit Auflagern versehen ist. Beide Teile werden im Mund des Patienten miteinander verεchraubt, eine Lösbarkeit ist späterhin nicht gegeben.A bridge of the aforementioned type has also become known (magazine "Neue Revue", spring 1987, page 94), in which the two-piece bridge consists of a so-called intermediate link (the replacement for the missing tooth) and a bracket part, which holds the two adjacent healthy teeth encompasses and is also provided with supports. Both parts are screwed together in the patient's mouth, and there is no later solubility.
Die Erfindung befaßt sich mit dem Problem, eine Prothese der eingangs genannten Art so auszugestalten, daß der Patient selbst die Prothese zwecks Säuberung leicht herausnehmen kenn und andererseits durch einfache Hendgriffe im Mund en Ort und Stelle wieder befestigen kann.The invention is concerned with the problem of designing a prosthesis of the type mentioned at the outset in such a way that the patient himself can easily remove the prosthesis for cleaning and, on the other hand, by simple handles in the mouth in place.
Erreicht wird dies durch die in den Ansprüchen engegeoenen Merkrale.This is achieved through the characteristics that are narrow in the claims.
Die Erfindung wird nachstehend an Hand der Zeichnung beispielsweise erläutert.The invention is explained below with reference to the drawing, for example.
Fig. 1 zeigt eine Draufsicht auf eine Brücke gemäß der Erfindung.Fig. 1 shows a top view of a bridge according to the invention.
Fig, 2 zeigt eineSeiten-Teilschnittansicht.Figure 2 shows a partial side sectional view.
In den Figuren ist mit 10 ein Brückenteil bezeichnet, der im wesentlichen die Form eines Zahnes hat und als Zwischenglied zwischen zwei gesunden Zehnen dienen kann. Bei Fig. 1 blickt men von oben auf die Kauflache des Zehnes 10. In Fig. 2 ist die Kauflache im oberen Bereich zu erkennen. Die benachbarten Zehne zum Brückenteil 10 sind bei Betrachtung der Fig, 2 vor der Zeichenebene und hinter der Zeichenebene zu denken.In the figures, 10 denotes a bridge part, which has essentially the shape of a tooth and can serve as an intermediate link between two healthy tens. In Fig. 1, men looks from above onto the purchase area of the toe 10. In Fig. 2, the purchase area can be seen in the upper area. The adjacent ten to the bridge part 10 are to be considered when looking at FIG. 2 in front of the drawing plane and behind the drawing plane.
Der Brückenteil 10 ist - bei Betrachtung nach Fig. 1 - mit vorspringenden Teilen 11 und 12 gezeigt. Diese Teile regen in die unter sich gehenden Bereiche der benachbarten gesunden Zähne hinein.The bridge part 10 - when viewed according to FIG. 1 - is shown with projecting parts 11 and 12. These parts stimulate the subsiding areas of the neighboring healthy teeth.
Im obere n B erei c h d e s Br ü c kent e il s 10 k önnen sich zwei Auflagerteile 13 und 14 befinden, die so ausgestaltet sind, daß sie auf den benachbarten Zähnen aufruhen können, so daß die Kaukräfte von der Keufläche des Brückenteils 10 über diese Auflager 13 und 14 auf die benachbarten Zähne geleitet werden.In the upper area of the bridge bridge 10 there can be two support parts 13 and 14, which are designed in such a way that they can rest on the adjacent teeth, so that the chewing forces from the mating surface of the bridge part 10 over them Bearings 13 and 14 are passed to the adjacent teeth.
Der Brückenteil 10 ist mit einer inneren Ausnehmung 15 ausgebildet, welcher in der Art eines Sackloches von hinten her in den Brückenteil 10 hineingeht. Am Grund (in den Figuren linksseitig gezeigt) der Ausnehmung 15 befindet sich eine weitere Sacklochöffnung 16, deren Zweck später erläutert wird.The bridge part 10 is formed with an inner recess 15 which goes into the bridge part 10 from behind in the manner of a blind hole. At the bottom (shown on the left in the figures) of the recess 15 there is a further blind hole opening 16, the purpose of which will be explained later.
In der Ausnehmung 15 des Brückenteils 10 befindet sich eine Scheibe 20, welche plattenförmig aber auch kreisförmig ausgestaltet seinkann. Diese Scheibe 20 ist fest mit dem Brückenteil 10 verbunden oder einstückig mit diesem ausgebildet.In the recess 15 of the bridge part 10 there is a disc 20, which can be plate-shaped but also circular. This disc 20 is fixed connected to the bridge part 10 or integrally formed therewith.
Die Scheibe 20 ist mit einer Bohrung 32 ausgebildet, die als Führung für einen Führungsstift 30 dient. Die Führungsbohrung 32 öffnet sich weiterhin mit einer Senkbohrung 21 zur Aufnahme des Kopfes 31 des Führungsstiftes 30. Es ist ersichtlich, daß die Scheibe 20 (und damit der Erückenteil 10) euf dem Führυngsstift 30 geführte Bewegungen durchführen kenn. Dabei kann der Kopf 31 des Führungsstiftes 30 in die Sacklochbohrung 16 hinein- und herausgelangen.The disc 20 is formed with a bore 32 which serves as a guide for a guide pin 30. The guide bore 32 continues to open with a counterbore 21 for receiving the head 31 of the guide pin 30. It can be seen that the disc 20 (and thus the back part 10) can perform movements performed on the guide pin 30. The head 31 of the guide pin 30 can get into and out of the blind hole 16.
Die Scheibe 20 ist mit einer weiteren Bohrung 22 ausgebildet, in die ein Hsken 51 eines Riegelteils 50 eingreifen kenn. Es kenn sich hierbei um eine Durchgangsbohrung handeln, es kann sich dabei auch um ein Vierkentloch handeln. Wichtig ist, daß die Bohrung so bemessen ist, daß der Haken 51 in die Öffnung 22 hinein- und herausgelangen kann.The disc 20 is formed with a further bore 22, in which a hack 51 of a locking part 50 is known to engage. This is a through hole, it can also be a square hole. It is important that the bore is dimensioned so that the hook 51 can get in and out of the opening 22.
Quer zur Bohrung 22, etwa senkrecht, ist in der Scheibe 20 ein Riegelstift 23 befestigt, der mit dem bereite erwähnten Haken 51 zusammenwirken kann.A locking pin 23 is fastened transversely to the bore 22, approximately perpendicularly, in the disk 20 and can cooperate with the hook 51 already mentioned.
In den Figuren ist mit 40 eine Gegenplatte oder ein Brückenanker bezeichnet, der im wesentlichen die Form einer Scheibe hat, jedoch mit einer oder zwei sich in seitlichen Richtungen erstreckenden Klammern 43 und 44 ausgebildet ist. Derertige Greifklammern sind in der Technik bekannt, sie sind hier nur schemetisch wiedergegeben und können jede geeignete Form heben, um die benachbarten Zähne umgreifen zu können.In the figures, 40 denotes a counterplate or a bridge anchor, which is essentially in the form of a disk, but is designed with one or two brackets 43 and 44 extending in the lateral directions. Such gripping clips are known in the art, they are only shown schematically here and can lift any suitable shape in order to be able to grip around the adjacent teeth.
Der bereits erwähnte Führungsstift 30 ist in einer Bohrung 41 des Brückenankers so befestigt, deß er sich nur zusammen mit dem Brückenteil 40 bewegen kann.The guide pin 30 already mentioned is fastened in a bore 41 of the bridge anchor so that it can only move together with the bridge part 40.
In einer Öffnung 43 ist der bereits erwähnte Riegel 50 em Bruckenenker 40 schwenkbar befestigt. Die Verschwenkung geschieht um einen Schwenkstift 42, der von der Seite her über eine Bohrung in den Brückenanker 40 zusammen mit dem Riegel 50 eingesetzt wird.In an opening 43, the already mentioned latch 50 is pivotally attached to the bridge counter 40. The pivoting takes place about a pivot pin 42, which is the Side is used together with the bolt 50 via a hole in the bridge anchor 40.
In den Figuren ist die sogenennte Außereingriffslage gezeigt, die die beiden Teile (Brückenteil 10 und Bruckenenker 40) zueinander einnehmen müssen, damit die mehrteilige Brücke en Ort und Stelle eingesetzt oder von dorther entnommen werden kann. Es ist ersichtlich, daß wegen der Vorsprünge 11 und 12 die Brücke nicht von oben her in die Zahnlücke eingesetzt werden kann, sondern in der Außereingriffslage durch eine seitliche Bewegung.In the figures, the so-called disengaged position is shown, which the two parts (bridge part 10 and bridge sinker 40) have to assume in relation to one another, so that the multi-part bridge can be inserted in place or removed from there. It can be seen that, because of the projections 11 and 12, the bridge cannot be inserted into the tooth gap from above, but in the disengaged position by a lateral movement.
Befinden sich die beiden Teile 10 und 40 in ihrer gezeigten räumlichen Lege zueinander an der vorgesehenen Stelle im Mund eines Petisnten, so werden die beiden Teile 10 und 40 aufeinander zu bewegt, Hierzu dient der Hebel 50, indem dieser im Uhrzeigersinn bei Betrachtung der Fig. 2 geschwenkt wird. Dadurch gelangt der Riegelstift 23 in die Öffnung des Hakens 51, so deß die beiden Teile 10 und 40 ihre Eingriffslage einnehmen, dies ist die Lage, in der die Brücke ihre eigentliche Funktion ausüben kenn.If the two parts 10 and 40 are in their shown spatial relationship to one another at the intended location in the mouth of a petit, the two parts 10 and 40 are moved towards each other. The lever 50 serves this purpose by turning it clockwise when looking at FIG. 2 is pivoted. As a result, the locking pin 23 gets into the opening of the hook 51, so that the two parts 10 and 40 assume their engagement position, this is the position in which the bridge knows its actual function.
Die Ausgestaltung des Hakene 51 bzw. seiner Öffnung ist derartig, daß durch keine Kaubewegung eine Trennung der beiden Teile 10 und 40 voneinander möglich ist. Derartige technische Lösungen sind bekannt (selbsthemmender Eingriff).The configuration of the Hakene 51 or its opening is such that the two parts 10 and 40 cannot be separated from one another by no chewing movement. Such technical solutions are known (self-locking intervention).
Der in den Mundinnenraum vorstehende Teil des Riegels 50 nimmt in der Eingriffslage eine solche Stellung ein, daß er ebenfslls durch keine süßeren Kräfte in Öffnungsrichtung beansprucht werden kann, Lediglich durch Hintergreifen mit dem Fingernagel kann der Riegel 50 bei Blickrichtung nach Fig. 2 im Gegenuhrzeigersinn verschwenktwerden, und die beiden Teile 10 und 40 in die in der Fig. 2 gezeigtenlage zurückgebrecht werden.The part of the bolt 50 protruding into the interior of the mouth assumes such a position in the engagement position that it cannot be subjected to any sweeter forces in the opening direction either. Only by reaching behind with the fingernail can the bolt 50 be pivoted counterclockwise when viewed in FIG. 2 , and the two parts 10 and 40 are broken back into the position shown in FIG. 2.
Der im Zusammenhang mit einer Brücke beschriebene Mechanismus kann euch en einer sogenannten Transversalverbindung eingesetzt werden, welche im Ober- oder Unterkiefer die verschiedenen Prothesenelemente in beiden Kieferhälften miteinander verbindet. Dies ermöglicht denn, nerausnehmbere Transversalverbindυngen zu realisieren, die selbst dann eingesetzt werde können, wenn oie d er Prothesenelemennten benachbarten Zähne stark divergierende Richtungen heben. Durch die Relativbeweglichkeit des eigentlichen Prothesenelementes in bezug auf den Anker, en dem sich die Klemmern bzw. Klammerarme befinden, kann die Divergenz der untersichgehenden Räume überwunden werden. The mechanism described in connection with a bridge can be used in a so-called transverse connection, which in the upper or lower jaw contains the various prosthetic elements in both jaw halves connects with each other. This makes it possible to realize transversal connections that are exceptionally good and which can be used even when the teeth adjacent to the prosthesis lift strongly diverging directions. The divergence of the spaces underneath can be overcome by the relative mobility of the actual prosthesis element with respect to the anchor, in which the clamps or clamp arms are located.
