Description
Dentalimplantat Dental implant
Beschreibungdescription
Die Erfindung bezieht sich auf ein Dentalimplantat nach den Merkmalen des Oberbegriffs.The invention relates to a dental implant according to the features of the preamble.
Im Einzelnen bezieht sich die Erfindung auf ein Dentalimplantat mit einem enossalen Bereich und einem koronalen Bereich. Der enossale Bereich wird in den Kieferknochen des Patienten eingeschraubt, während auf den koronalen Bereich ein Aufbau, beispielsweise eine Zahnkrone, montiert wird. Dentalimplantate oder Zahnimplantate der genannten Art sind aus dem Stand der Technik in unterschiedlichsten Ausgestaltungsformen vorbekannt. Beispiele hierfür zeigt die DE 102 51 469 Al.In particular, the invention relates to a dental implant having an endosteal area and a coronal area. The enossal area is screwed into the jawbone of the patient, while on the coronal area a structure, such as a dental crown, is mounted. Dental implants or dental implants of the type mentioned are already known from the prior art in a variety of embodiments. Examples of this are shown in DE 102 51 469 A1.
Aus dem Stand der Technik sind zunächst einteilige Dentalimplantate oder Kieferimplantate bekannt, welche beispielsweise aus Titan gefertigt sind. Als nachteilig kann es sich hierbei erweisen, dass der metallische Werkstoff im Übergangsbereich zwischen dem enossalen und dem koronalen Bereich, d.h., in dem Bereich, in welchem das Zahnfleisch an das Dentalimplantat anliegt, zu unerwünschten Reaktionen des Patienten führt oder aus optischen Gründen unerwünscht ist.
Weiterhin zeigt der Stand der Technik zweiteilige Dentalimplantate, beispielsweise mit einem enossalen Bereich aus Titan und einem koronalen Bereich aus Keramik. Dabei wird der enossale Bereich zunächst in einen Kieferknochen eingesetzt, um dort einzuwachsen. In einem zweiten Schritt wird dann auf den enossalen Bereich der koronale Bereich aufgebracht. Dies erfolgt mittels Schraub- oder Klebeverbindung. Die Fügefläche liegt dabei im Bereich des Zahnfleischs. Dies ergibt das Problem, dass zum einen nicht spaltfrei gearbeitet werden kann und dass zum anderen Klebstoffreste austreten oder überstehen können. Beides führt zu unerwünschten Reaktionen des Patienten.From the prior art, one-piece dental implants or jaw implants are first known, which are made for example of titanium. It may prove to be disadvantageous here that the metallic material in the transition region between the endosseous and the coronal region, ie, in the region in which the gum rests against the dental implant, leads to undesired reactions of the patient or is undesirable for optical reasons. Furthermore, the prior art shows two-part dental implants, for example with an endosseous region of titanium and a coronal region of ceramic. The enossal area is first inserted into a jawbone to grow in there. In a second step, the coronal area is then applied to the endosseous area. This is done by means of screw or adhesive connection. The joining surface lies in the area of the gum. This results in the problem that, on the one hand, it is not possible to work without gaps and, on the other hand, that adhesive residues can escape or survive. Both lead to unwanted reactions of the patient.
Die WO 01/34056 Al zeigt eine Variante eines einstückigen metallischen Dentalimplantats, welches im koronalen Bereich mit einer keramischen Beschichtung versehen ist. Abhängig vom Material der Krone erweist es sich dabei als nachteilig, dass der metallische Kern, der zur Kraftübertragung und zur Befestigung des Aufbaues bzw. der Krone dient, optisch durchscheinen kann, so dass das Erscheinungsbild des Dentalimplantats ungünstig ist.WO 01/34056 A1 shows a variant of a one-piece metallic dental implant, which is provided with a ceramic coating in the coronal area. Depending on the material of the crown, it proves to be disadvantageous that the metallic core, which is used for power transmission and for attachment of the structure or the crown, can shine through optically, so that the appearance of the dental implant is unfavorable.
Der Erfindung liegt die Aufgabe zugrunde, ein Dentalimplantat der eingangs genannten Art zu schaffen, welches bei einfachem Aufbau und einfacher, kostengünstiger Herstellbarkeit leicht und problemlos durch einen Zahnarzt einsetzbar ist und die Nachteile des Standes der Technik vermeidet.The invention has for its object to provide a dental implant of the type mentioned, which is easily and easily used by a dentist with a simple design and simple, cost manufacturability and avoids the disadvantages of the prior art.
Erfindungsgemäß wird die Aufgabe durch die Merkmalskombination des Hauptanspruchs gelöst, die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der Erfindung.According to the invention the object is achieved by the feature combination of the main claim, the subclaims show further advantageous embodiments of the invention.
Erfindungsgemäß ist somit vorgesehen, dass das Dentalimplantat einstückig oder einteilig ausgebildet ist, wobei der enossale Bereich aus einem metallischen Werkstoff gefertigt ist und
einstückig mit dem koronalen Bereich verbunden ist, welcher aus einem keramischen Material besteht. Das erfindungsgemäße Dentalimplantat ist somit werksseitig fertiggestellt und kann vom Zahnarzt direkt eingesetzt werden. Es ist nicht erforderlich, im Operationsfeld Teile aneinander zu fügen oder zu montieren. Hierdurch wird auch die Gefahr vermieden, dass die Montage des koronalen Bereichs auf dem enossalen Bereich nicht korrekt erfolgt. Insbesondere wird eine Spaltbildung zwischen dem enossalen und dem koronalen Bereich ausgeschlossen, da dies bei der werksseitigen Fertigung zuverlässig kontrolliert werden kann. Zusätzlich wird vermieden, dass Kleber oder anderes Fügematerial, welches unvermeidlich im Übergangsbereich bei einem zweiteiligen Dentalimplantat, welches durch einen Zahnarzt zusammengesetzt wird, vorhanden ist, austritt und insbesondere in den Knochenbereich gelangen kann, wo es heftige Reaktionen und Probleme beim Patienten verursachen kann.According to the invention it is thus provided that the dental implant is formed in one piece or in one piece, wherein the endosseous area is made of a metallic material and is integrally connected to the coronal region, which consists of a ceramic material. The dental implant according to the invention is thus completed at the factory and can be used directly by the dentist. It is not necessary to join or assemble parts in the surgical field. This also avoids the risk that the assembly of the coronal area on the enossal area is not done correctly. In particular, a gap formation between the endosseous and the coronal area is excluded, since this can be reliably controlled during factory production. In addition, glue or other joining material which is inevitably present in the transition region in a two-part dental implant which is assembled by a dentist is prevented from escaping and in particular may enter the bone area where it may cause severe reactions and problems for the patient.
Das erfindungsgemäße Dentalimplantat wird somit werksseitig vorgefertigt und kann so ausgebildet sein, dass auf den koronalen Bereich direkt ein Aufbau oder eine Zahnkrone montiert werden kann oder dass der koronale Bereich nur noch geringfügig bearbeitet werden muss. In beiden Fällen ergibt sich eine sehr verkürzte Arbeitszeit des Zahnarztes, wodurch das erfindungsgemäße Dentalimplantat kostengünstig einsetzbar ist. Weiterhin werden Fehler bei der Montage des Dentalimplantats und bei dessen Einsetzung ausgeschlossen. Insgesamt ergibt sich somit ein hohes Maß an Komfort und Sicherheit .The dental implant according to the invention is thus prefabricated at the factory and can be designed so that a structure or a tooth crown can be mounted directly on the coronal area or that the coronal area only has to be processed slightly. In both cases results in a very reduced working time of the dentist, whereby the dental implant according to the invention is inexpensive to use. Furthermore, errors in the assembly of the dental implant and its insertion are excluded. Overall, this results in a high degree of comfort and safety.
Der Verbindungsbereich zwischen dem koronalen Bereich und dem enossalen Bereich ist bevorzugterweise erfindungsgemäß völlig spaltfrei ausgebildet. Dies kann durch eine Nachbearbeitung dieses Bereichs, beispielsweise mittels Polieren oder Schleifen erfolgen und durch geeignete Kontrollmaßnahmen sichergestellt sein.
Im Rahmen der Erfindung ergeben sich unterschiedlichste Ausführungsvarianten für den Verbindungsbereich. Dieser kann als kraftschlüssige Fügeverbindung, beispielsweise durch Schweißen, Löten oder Kleben gefertigt sein. Es ist jedoch auch möglich, den Verbindungsbereich formschlüssig, gegebenenfalls zusätzlich zu einem Schweiß-, Klebe- oder Lötverfahren auszubilden. Die formschlüssige Koppelung führt zu einer erhöhten mechanischen Festigkeit. Es ist auch möglich, den koronalen und den enossalen Bereich mittels eines Gewindes oder einer bajonettverschlussartigen Ausgestaltung miteinander zu koppeln und gegebenenfalls nachfolgend zu verkleben, zu verschweißen oder zu verlöten. Auch hierdurch ergibt sich ein hohes Maß an mechanischer Festigkeit, insbesondere bei einem koronalen Bereich aus einem Keramikwerkstoff .The connecting region between the coronal region and the endosseous region is preferably formed completely without a gap according to the invention. This can be done by a post-processing of this area, for example by means of polishing or grinding and be ensured by appropriate control measures. In the context of the invention, a wide variety of design variants for the connection area arise. This can be made as non-positive joining connection, for example by welding, soldering or gluing. However, it is also possible to form the connection region in a form-fitting manner, optionally in addition to a welding, adhesive or soldering process. The positive coupling leads to increased mechanical strength. It is also possible to couple the coronal and the enossal area with one another by means of a thread or a bayonet-type embodiment and, if appropriate, subsequently to glue, to weld or to solder. This also results in a high degree of mechanical strength, especially in a coronal region of a ceramic material.
Weiterhin ist im Rahmen der Erfindung vorgesehen, dass der koronale Bereich und der enossale Bereich formschlüssig miteinander in Eingriff sind, beispielsweise durch konkave oder konvexe Teilbereiche. Hierdurch erhöht sich auch die Fügefläche, wodurch die mechanische Belastbarkeit gesteigert werden kann .Furthermore, it is provided in the context of the invention that the coronal area and the endosseous area are positively engaged with each other, for example, by concave or convex portions. This also increases the joint surface, whereby the mechanical strength can be increased.
Besonders günstig ist es, wenn das erfindungsgemäße Dentalimplantat so dimensioniert ist, dass sich der Verbindungsbereich zwischen dem koronalen Bereich und dem enossalen Bereich bei eingesetztem Dentalimplantat im Bereich des Zahnfleisches des Patienten befindet. Das Zahnfleisch liegt somit im Wesentlichen bevorzugterweise gegen den keramischen Werkstoff des koronalen Bereichs an. Dies dient zum einen der Verbesserung der Optik und zum anderen zur Verbesserung der körperlichen und medizinischen Akzeptanz durch den Patienten.
Der enossale Bereich ist bevorzugterweise mit zumindest einem Außengewinde versehen, so wie dies auch aus dem Stand der Technik bekannt ist.It is particularly favorable if the dental implant according to the invention is dimensioned such that the connection area between the coronal area and the enossal area when the dental implant is inserted is located in the area of the gum of the patient. The gum is thus substantially preferably against the ceramic material of the coronal area. This serves on the one hand to improve the appearance and on the other to improve the physical and medical acceptance by the patient. The endosseous region is preferably provided with at least one external thread, as is known from the prior art.
Die Strukturierung und Ausgestaltung des koronalen Bereichs kann den jeweiligen Anforderungen angepasst werden. So ist es beispielsweise möglich, diesen an die jeweilige Zahnform vorab anzupassen, um den Zahnaufbau bzw. das Aufsetzen einer Krone zu erleichtern.The structuring and design of the coronal area can be adapted to the respective requirements. Thus, it is possible, for example, to adapt it in advance to the respective tooth shape in order to facilitate the tooth structure or the placement of a crown.

Es ist jedoch auch möglich, andere keramische Werkstoffe zu verwenden oder eine Mischkeramik bzw. Diffusionskeramik vorzusehen.Integral with the endosseous region 1 is a coronal region 2, which is made of a ceramic material, for example zirconium oxide ceramic. However, it is also possible to use other ceramic materials or to provide a mixed ceramic or diffusion ceramic.
