Description

Die Erfindung betrifft ein ennosales Implantat, insbesondere Dentalimplantat, nach dem Oberbegriff des Patentanspruches 1.The invention relates to an endoscopic implant, in particular Dental implant, according to the preamble of claim 1.

Aus der DE 26 11 744 C2 ist ein solches Implantat bekannt, bei dem der Schwingkörper Bestandteil eines innerhalb des Implantates angeordneten Wechselspannungsgenerators ist, der aus einer Spulenanordnung und einem darin federnd beweglich gelagerten Permanentmagneten besteht. Durch die Bewegung des Implantatträgers und die dadurch hervorgerufenen leichten Schwingungen des federnd gelagerten Permanentmagneten wird eine niederfrequente elektrische Wechselspannung erzeugt die in dem das Implantat umgebenden Gewebe durch das ent­ sprechende Magnetfeld eine knochenwachstumsfördernde Wirkung ausübt. Das Wirkungsprinzip des vorstehend beschriebenen Enossalen Implantats besteht also darin, zur Vitalerhaltung von Knochengewebe für Endoprothesen elektromagnetische Wech­ selfelder einzusetzen.Such an implant is known from DE 26 11 744 C2, in which the vibrating body is part of a within the Implant arranged AC voltage generator is the from a coil arrangement and one resiliently movable therein  stored permanent magnet. By moving the Implant carrier and the resulting light Vibrations of the spring-loaded permanent magnet generates a low-frequency electrical AC voltage in the tissue surrounding the implant through the ent speaking magnetic field a bone growth-promoting effect exercises. The principle of action of that described above Endosseous implant therefore consists in maintaining vitality of bone tissue for endoprostheses electromagnetic altern use selfelder.

Auf einem ähnlichen Prinzip beruht ein aus der US 40 27 392 bekanntes Dentalimplantat, bei dem über eine vorübergehend eingesetzte Verschlußschraube mit Hohlraum elektromagneti­ sche Wechselfelder, die durch entsprechende Stromzufuhr von außen oder mittels eingesetzter Batterie erzeugt werden, zur Förderung des Einheilprozesses verwendet werden.A principle from US Pat. No. 4,027,392 is based on a similar principle known dental implant, in which a temporary used screw plug with cavity electromagnetic alternating fields caused by the corresponding power supply from generated outside or by means of an inserted battery for Promotion of the healing process can be used.

Aus beispielsweise der EP 36 72 091 A1 ist ein Dentalimplan­ tat mit einem im Knochengewebe implantierbaren, im wesentli­ chen zylindrischen Grundkörper, vorzugsweise aus Metall, wie Titan oder einer Metallegierung bestehend, bekannt, in des­ sen zur Aufnahme eines Implantatpfostens oder dergleichen ausgebildete Innenbohrung insbesondere während des Einheil­ vorgangs eine Verschlußschraube lösbar einsetzbar ist. Nach dem Einsetzen des Grundkörpers in eine in das Knochengewebe eingebrachte Bohrung wird dabei für Einheilzwecke vorüber­ gehend statt des später vorgesehenen Implantatpfostens, der zum Tragen des Zahnaufbaus vorgesehen ist, eine Verschluß­ schraube eingesetzt, welche die Innenbohrung des Grundkör­ pers nach außen steril abschließt. Sobald der Grundkörper in das Grundgewebe eingeheilt ist, wird die Verschlußschraube herausgenommen, woraufhin dann in die Innebohrung der Implantatpfosten eingebracht und dort befestigt wird. Der Grundkörper kann dabei mit einem Innengewinde zum Aufnehmen der Verschlußschraube versehen sein, jedoch kann es sich auch um eine gewindefreie "Verschlußschraube" handeln, so daß also unter "Verschlußschraube" in diesem Zusammenhang ggf. auch solche vorübergehend verwendbare Verschlußelemente verstanden werden, die in die Innenbohrung des Grundkörpers nicht eingeschraubt, sondern hier beispielsweise durch eine lösbare Klebeverbindung angebracht werden.For example, EP 36 72 091 A1 is a dental implant did with an implantable in the bone tissue, essentially Chen cylindrical base body, preferably made of metal, such as Titanium or a metal alloy, known in the sen for receiving an implant post or the like trained inner bore especially during healing operation a screw plug is releasably insertable. To the insertion of the body into one in the bone tissue Drilled hole is over for healing purposes instead of the implant post planned later, the is provided for carrying the tooth structure, a closure screw inserted, which the inner bore of the basic body pers closes sterile to the outside. Once the body is in the base tissue has healed, the locking screw removed, whereupon then in the inner bore of the Implant post inserted and attached there. Of the  The base body can have an internal thread for receiving the screw plug, but it can be also act as a thread-free "screw plug", so that under "screw plug" in this context possibly also such temporarily usable closure elements be understood in the inner bore of the base body not screwed in, but here, for example, by a releasable adhesive connection can be attached.

Der Einheilprozeß des Grundkörpers dauert in der Regel meh­ rere Monate, wobei es natürlich für den Patienten angenehm wäre, diesen Einheilprozeß soweit wie möglich verkürzen zu können.The healing process of the body usually takes a long time later months, although of course it is pleasant for the patient would be to shorten this healing process as much as possible can.

Dies hat sich bislang als schwierig erwiesen, insbesondere deshalb, weil dem Grundkörper, der ja im Einheilprozeß noch nicht mit dem Zahnaufbau in Verbindung steht, die ansonsten beim Kauen etc., nämlich bei Dentalimplantaten oder anson­ sten bei Körperbewegungen auftretende regelmäßige oder un­ regelmäßige mechanische Belastung fehlt, die wie sich ge­ zeigt hat, zur Stimulation des Knochenwachstums förderlich ist.This has proven difficult so far, especially because the basic body, which is still in the healing process not related to the tooth structure, which otherwise when chewing etc., namely with dental implants or otherwise Most regular or unpleasant body movements regular mechanical stress is missing, which like ge shows, stimulates bone growth is.

Der Erfindung liegt die Aufgabe zugrunde, das Enossale Im­ plantat der gattungsgemäßen Art dahingehend weiterzubilden, daß durch mechanische Stimulation der Einheilvorgang be­ schleunigt werden kann. Ferner soll eine in Verbindung mit einem derartigen Enossalen Implantat verwendbare Einheil­ hilfe geschaffen werden.The invention is based, the endosseous Im to further develop a implant of the generic type that by mechanical stimulation the healing process be can be accelerated. Furthermore, one is said to be in connection with Healing usable in such an endosseous implant help be created.

Erfindungsgemäß wird diese Aufgabe in Weiterbildung des gat­ tungsgemäßen Implantats durch die Merkmale des Kennzeichens des Patentanspruches 1 gelöst. According to the invention, this task is further developed in gat according to the implant by the features of the mark of claim 1 solved.  

Besondere Ausführungsformen der Erfindung sind Gegenstand der Patentansprüche 2 und 3.Particular embodiments of the invention are the subject of claims 2 and 3.

Die Einheilhilfe für ein Enossales Implantat der erfin­ dungsgemäßen Art ist nach der Erfindung durch das den Gegen­ stand des Patentanspruches 4 bildende Merkmal gekennzeich­ net.The healing aid for an endosseous implant of the inventor Invention is according to the invention by the counter Stand of claim 4 characteristic feature net.

Besondere Ausführungsformen der Einheilhilfe nach der Erfin­ dung sind Gegenstand der Patentansprüche 5 und 6.Special embodiments of the healing aid according to the inven dung are the subject of claims 5 and 6.

Der Erfindung liegt die überraschende Erkenntnis zugrunde, daß es gelingt, das Wachstum des Knochengewebes und damit das Einheilen des Grundkörpers beschleunigende Stimulations­ wirkungen dadurch zu erzielen, daß innerhalb eines Hohlrau­ mes der herkömmlichen Verschlußschraube, der natürlich nach außen steril abgeschlossen ist, ein mechanisch wirkender Schwingkörper angeordnet wird. Dieser Schwingkörper, der we­ sentlich geringere Außenabmessungen hat als der innere Hohl­ raum der Verschlußschraube, kann beispielsweise aus einem sehr schweren Metall bestehen, wie Wolfram vgl., und kann dann bewirkt durch die natürlichen Kopfbewegungen (bei Den­ talimplantaten), insbesondere auch infolge der Kiefer­ bewegungen beim Kauen, auf mechanische Weise in dem Hohlraum hin- und herschwingen und hierdurch die gewünschten mechani­ schen Stimulationen bewirken. Es kann aber auch vorgesehen sein, z. B. nach Art eines Magnetrührers, den Schwingkörper durch zeitweise in den Mund eingeführte oder an die Wange des Trägers herangeführte Schwingungserzeuger, wie sie für Laborzwecke bekannt sind, zeitweise in Schwingungen zu ver­ setzen.The invention is based on the surprising finding that it succeeds in the growth of the bone tissue and thus stimulation accelerating the healing of the basic body to achieve effects in that within a Hohlrau with the conventional screw plug, which of course follows is sterile on the outside, a mechanical one Vibrating body is arranged. This vibrating body, the we has considerably smaller outer dimensions than the inner hollow space of the screw plug, for example from a very heavy metal, as Wolfram cf., and can then caused by the natural head movements (in Den valley implants), especially as a result of the jaw movements when chewing, mechanically in the cavity swing back and forth and thereby the desired mechani stimulations. But it can also be provided be, e.g. B. in the manner of a magnetic stirrer, the vibrating body by being temporarily inserted into the mouth or on the cheek of the wearer brought up vibration generators, as for Laboratory purposes are known to temporarily vibrate put.

Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der schematischen Zeichnung im Einzelnen erläutert.Below is an embodiment of the invention based on the schematic drawing explained in detail.

Dabei zeigt die aus einer einzigen Figur bestehenden Zeichnung ein enossales Dentalimplantat nach der Erfindung im axialen Schnitt durch die Längsachse des Grundkörpers.It shows the one figure Drawing an endosseous dental implant according to the invention in axial section through the longitudinal axis of the base body.

Wie die Zeichnung erkennen läßt, weist das enossale Den­ talimplantat einen Grundkörper 10 aus einer Titanlegierung auf, der in bekannter Weise, wie in der EP 36 72 091 A1 beschrieben, in z. B. einen Kieferknochen implantiert wer­ den kann. Der Grundkörper ist mit Eindellungen 12 ver­ sehen, die den Einheilprozeß beschleunigen, und kann ggf. hydroxylapatitbeschichtet sein. In einer Innenbohrung des Grundkörpers 10 ist eine Verschlußschraube 14 vorüber­ gehend, nämlich während des Einheilprozesses, einge­ schraubt, die einen inneren Hohlraum 16 aufweist und über eine Steckereinrichtung 18 für einen Schraubenschlüssel oder dergleichen betätigbar ist. Innerhalb des Hohlraumes 16 befindet sich ein kernartiger Schwingkörper 20 aus Wolfram, der schon bei leichten Kopfbewegungen des Trägers, insbesondere aber auch beim Kauen, innerhalb des Hohlraumes in Richtung der gezeigten vier Pfeile Hin- und Herbewegungen ausführt, welche mechanische Stoßbean­ spruchungen der Hohlraumwandungen bewirken, die auf den Grundkörper 10 übertragen werden und an dessen Kontakt­ flächen mit dem Knochengewebe die Stimulation des Knochen­ wachstums und damit den Einheilprozeß beschleunigen.As the drawing shows, the endosseous den implant has a base body 10 made of a titanium alloy, which in a known manner, as described in EP 36 72 091 A1, in z. B. implanted a jawbone who can. The base body is seen with indentations 12 , which accelerate the healing process, and can optionally be coated with hydroxyapatite. In an inner bore of the base body 10 , a screw plug 14 is temporary, namely during the healing process, is screwed, which has an inner cavity 16 and can be actuated via a plug device 18 for a wrench or the like. Within the cavity 16 there is a core-like oscillating body 20 made of tungsten, which makes slight back and forth movements within the cavity in the direction of the four arrows shown, even with slight head movements of the wearer, but especially when chewing, which cause mechanical shock loads on the cavity walls, which are transferred to the base body 10 and at its contact surfaces with the bone tissue stimulate the bone growth and thus accelerate the healing process.

Die in der vorstehenden Beschreibung, in der Zeichnung sowie den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschie­ denen Ausführungsformen wesentlich sein.The in the above description, in the drawing and the features of the invention disclosed in the claims can be used individually or in any combination for the implementation of the invention in its various which embodiments are essential.
