Description

Dentales Implantatset  Dental implant kit
Die Erfindung betrifft ein dentales Implantatset gemäß dem Oberbegriff des Anspruches 1. The invention relates to a dental implant set according to the preamble of claim 1.
Implantate, Knochenersatzmaterialien, Membrane sowie chirurgische Instrumente, insbesondere Implantatbohrer, werden als essentielle Bestandteile und Instrumentarien im Rahmen einer Implantatbehandlung bei nicht optimalen Knochenverhältnissen eingesetzt. Implants, bone substitute materials, membranes and surgical instruments, especially implant drills, are used as essential components and instruments in the context of implant treatment in suboptimal bone conditions.
Ursache dieser nicht optimalen Knochenverhältnisse ist die oftmals große zeitliche Distanz zwischen Zahnverlust und Implantation. Hierdurch kommt es teilweise zu einer unregelmäßigen Atrophie, d .h. zu einer Rückbildung bzw. Abbau der Kieferkämme sowohl in vertikaler als auch in transversaler Richtung. The cause of these non-optimal bone conditions is the often large time interval between tooth loss and implantation. This partially leads to an irregular atrophy, ie. to a regression or degradation of the alveolar ridges in both the vertical and in the transverse direction.
Präimplantativ wird hierzu zunächst nach Öffnen des Zahnfleisches an der gewählten Implantatstelle mittels eines Schnittes oder einer Stanze mit Implantatbohrern der Knochen für die geplante Position und Implantatgröße aufbereitet. Aus dem Stand der Technik ist eine Vielzahl von Implantatbohrern bekannt. For this purpose, the bone is initially prepared for the planned position and implant size by means of a cut or a punch with implant drills after opening the gum at the selected implant site. From the prior art, a variety of implant drills is known.
Durch Einsatz von synthetisch hergestellten granulären Knochenersatzmaterialien werden dann die abgebauten Anteile der zahntragenden Knochen rekonstruiert. Ein Beispiel für ein granuläres Knochenersatzmaterial geht aus der DE 10 2006 037 362 B3 hervor, die ein Knochenersatzmaterial offenbart, das Calciumcarbonat enthält. By using synthetically produced granular bone replacement materials, the degraded portions of the tooth-bearing bones are then reconstructed. An example of a granular bone replacement material is disclosed in DE 10 2006 037 362 B3, which discloses a bone substitute material containing calcium carbonate.
Durch Einsatz von zusätzlichen Membranen wird dabei eine Abschirmung gegen die Invasion von Bindegewebe erreicht, was die knöcherne Regeneration des Defektes verhindern würde. Als Materialien für Membrane werden im Stand der Technik bevorzugt synthetische Polymere, wie Polylactide oder Polyglycolide sowie deren chemische Modifikation verwendet. Bei den Membranen handelt es sich um sehr dünne elastische Folien. Man unterscheidet resorbierbare Membranen, die vom Körper abgebaut werden und nicht entfernt werden müssen, sowie nicht resorbierbare Membranen. Alternativ wird intraimplantativ nach Einbringen des dentalen Implantats der verbliebene Knochendefekt mit synthetischem Knochenersatzmaterial aufgefüllt und wiederum mit einer Membran versehen. By using additional membranes, a shield against the invasion of connective tissue is achieved, which would prevent the bony regeneration of the defect. As materials for membranes, synthetic polymers such as polylactides or polyglycolides and their chemical modification are preferably used in the prior art. The membranes are very thin elastic films. A distinction is made between resorbable membranes which are broken down by the body and do not need to be removed, as well as nonabsorbable membranes. Alternatively, after implantation of the dental implant, the remaining bone defect is filled up with synthetic bone substitute material and, in turn, provided with a membrane.
Die aus dem Stand der Technik bekannten Knochenersatzmaterialien besitzen eine körnige Struktur und haben, je nach Korngröße, nach dem Einbringen die Eigenschaft, unter äußerem Druck verpresst werden zu können, was zu einer nicht gewünschten Unregelmäßigkeit in der sich final bildenden Knochenstruktur führt. Derartige Veränderungen der Augmentationsstruktur, d .h. der Vergrößerung der Knochenmasse, können bereits durch den Vorgang des Nahtverschlusses der Implantationswunde intraoperativ induziert werden. The bone substitute materials known from the prior art have a granular structure and, depending on the particle size, after introduction have the property of being compressible under external pressure, which leads to an undesired irregularity in the final bone structure. Such changes in the augmentation structure, i. E. The increase in bone mass can already be induced intraoperatively by the process of suture closure of the implantation wound.
Zudem bietet die Elastizität und Plastizität der derzeitig verwendeten Membrane bei der Augmentation keinen ausreichenden Schutz vor einer externen Kompression. Die herkömmlich eingesetzten Membrane liefern momentan auch keine optimale Abschirmung vor invasierenden Bindegewebszellen. Die zirkulär erforderliche, subperiostale, d.h. unter dem Knochenoberhäutchen befindliche Knochenstärke um das Implantat von 1,5 bis 2 mm wird darüber hinaus im Rahmen der Verwendung der herkömmlichen Knochenersatzmaterialien in Verbindung mit der Membran oftmals unterschritten, was die Prognose der Dauerhaftigkeit des Implantats erheblich verschlechtert. In addition, the elasticity and plasticity of the currently used membrane in the augmentation does not provide sufficient protection against external compression. The conventionally used membranes do not currently provide optimal shielding from invasive connective tissue cells. The circularly required, subperiosteal, i. Moreover, bone strength around the implant of 1.5 to 2 mm located beneath the bone membrane is often undershot as a result of the use of the conventional bone substitute materials in conjunction with the membrane, which considerably impairs the prognosis of the durability of the implant.
Es ist deshalb Aufgabe der vorliegenden Erfindung, ein dentales Implantatset der eingangs genannten Art zur Verfügung zu stellen, dessen Komponenten die Nachteile der herkömmlichen Praxis der Augmentation beseitigen. It is therefore an object of the present invention to provide a dental implant set of the type mentioned above, whose components eliminate the disadvantages of the conventional practice of augmentation.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen. This object is achieved with the features of claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Knochenersatzmaterial und die Membran von harter und fester Beschaffenheit sind . Kernidee der Erfindung ist es, eine elastische Verformung mit einer einhergehenden Volumenveränderung und Dichteerhöhung des Knochenersatzmateriales und der Membran durch eine inkompressible Ausbildung des Knochenersatzmateriales und der Membran zu vermeiden. Ein fester und harter Zustand des granulären Knochenersatzmateriales sowie der Membran, beispielsweise aus Polylactid, ist nahezu in- kompressibel . Die Überführung eines körnigen (granulären) Stoffes für das Knochenersatzmaterial in einen festen und harten Zustand kann durch herkömmliche Verfahren, beispielsweise durch Sintern oder Verklebung mittels Fibrinkleber erfolgen. Die Überführung der Membran in einen harten und festen Zustand kann ebenfalls durch herkömmliche Methoden realisiert werden. The object is achieved in that the bone substitute material and the membrane of hard and firm nature. The core idea of the invention is to avoid elastic deformation with a concomitant change in volume and increase in density of the bone substitute material and the membrane due to incompressible formation of the bone substitute material and of the membrane. A solid and hard state of the granular bone substitute material as well as the membrane, for example of polylactide, is almost incompressible. The transfer of a granular material for the bone substitute material to a solid and hard state can be accomplished by conventional methods such as sintering or gluing with fibrin glue. The transfer of the membrane into a hard and solid state can also be realized by conventional methods.
Nach den üblichen Einheil- und Osteoregenerationszeiten wird vorteilhafterweise eine definierte Alveolarknochensituation mit einer optimalen Knochenstärke erreicht. Hierdurch entfallen präimplantative, operative Zusatzeingriffe, was Zeit und Kosten minimiert. After the usual healing and osteoregeneration times, a defined alveolar bone situation with an optimal bone strength is advantageously achieved. This eliminates pre-implantative surgical intervention, which minimizes time and costs.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass das Set als chirurgisches Instrument einen Planfräser aufweist. Planfräser haben schon Verwendung im Rahmen von medizinischen Behandlungen gefunden, wie die DE 20 2007 003 035 U l für die Knieendoprothesenversorgung zeigt. An advantageous development of the invention provides that the set has a face milling cutter as a surgical instrument. Face milling cutters have already found use in the context of medical treatments, as shown in DE 20 2007 003 035 U 1 for knee endoprosthesis care.
Für die dentale Implantologie kommt zweckmäßigerweise ein Stirnplanfräser in Betracht, der über eine unterseitige Schneidefläche verfügt, womit ein Hohlraum oberhalb der für das Implantat geschaffenen Kavität erzeugt werden kann, der einen größeren Durchmesser als die Kavität aufweist. Das eingesetzte und in die Kavität eingeschraubte Implantat ragt dabei in den Hohlraum hinein, so dass das erfindungsgemäße Knochenersatzmaterial um den oberen Bereich des Implantats anordbar ist. Das vorzugsweise ringförmig um das Implantat bündig angeordnete Knochenersatzmaterial bildet so eine kraft- und formschlüssige Verbindung mit dem Implantat, wie auch nach der Inkorporation mit dem umgebenden Knochen. Anspruch 6 sieht daher vor, dass das Knochenersatzmaterial ringförmig ausgebildet ist. Eine praktikable Variante der Erfindung sieht vor, dass das Set als chirurgisches Instrument einen Bohrfräser aufweist. Die Verwendung von Bohrfräsern in der Zahnheilkunde ist bekannt. Die DE 35 43 737 AI offenbart einen Bohrfräser für die Wurzelbehandlung . Die Verwendung eines Bohrfräsers hat den Vorteil, dass die Erzeugung der Kavität für das Implantat und die Erzeugung des Hohlraumes für das Knochenersatzmaterial in einem Arbeitsgang vollzogen werden kann. For dental implantology, an end-face milling cutter is expediently suitable, which has a lower-side cutting surface, whereby a cavity above the cavity created for the implant can be produced, which has a larger diameter than the cavity. The inserted and screwed into the cavity implant protrudes into the cavity, so that the bone substitute material according to the invention can be arranged around the upper region of the implant. The bone replacement material, which is preferably arranged in a ring around the implant, thus forms a non-positive and positive connection with the implant, as well as after incorporation with the surrounding bone. Claim 6 therefore provides that the bone substitute material is annular. A practicable variant of the invention provides that the set has a drill bit as a surgical instrument. The use of drill bits in dentistry is known. DE 35 43 737 AI discloses a drill bit for root canal treatment. The use of a drill has the advantage that the generation of the cavity for the implant and the generation of the cavity for the bone substitute material can be completed in one operation.
Zudem sieht die Erfindung ein dentales Implantat vor, das mit einem Knochenersatzmaterial aus Granulat versehen ist, wobei das Knochenersatzmaterial von fester und harter Beschaffenheit ist. Vorgesehen ist also ein einteiliges Gebilde, das sich aus dem Implantat und dem Knochenersatzmaterial zusammensetzt. Zusätzlich kann das Implantat vorzugsweise mit einer festen und harten Membran versehen sein. Sämtliche Bestandteile, d .h. Implantat, Knochenersatzmaterial und Membran, können dabei zweckmäßigerweise lösbar miteinander verbunden sein. In addition, the invention provides a dental implant provided with a bone substitute material of granules, the bone substitute material being of firm and hard nature. So provided is a one-piece structure, which is composed of the implant and the bone substitute material. In addition, the implant may preferably be provided with a solid and hard membrane. All components, ie. Implant, bone substitute material and membrane, while expediently be releasably connected together.
Schließlich sieht die Erfindung auch die Verwendung des erfindungsgemäßen Kno- chenersatzmateriales, der erfindungsgemäßen Membran sowie die Verwendung des Planfräsers für die dentale Implantologie vor. Finally, the invention also provides for the use of the bone substitute material according to the invention, the membrane according to the invention and the use of the face milling cutter for dental implantology.

Fig . 2 in einer Schnittansicht eine für das Implantat erzeugte Kavität und ein für das Knochenersatzmaterial erzeugter Hohlraum in einem Kieferknochen, Fig. 2 shows in a sectional view a cavity produced for the implant and a cavity for the bone substitute material in a jawbone,
Fig . 3 in einer Schnittansicht einen Planfräser als weitere Komponente des erfindungsgemäßen dentalen Implantationssets, wobei der Planfräser während des Einsatzes bei einer dentalen Implantologie gezeigt ist und Fig . 4 die Schritte einer dentalen Implantologie in einer Schnittansicht, bei denen Komponenten des erfindungsgemäßen dentalen Implantatsets eingesetzt werden. Fig. 3 is a sectional view of a face milling cutter as a further component of the dental implantation set according to the invention, the face milling cutter being shown during use in a dental implantology, and Fig. 4 shows the steps of a dental implantology in a sectional view, in which components of the dental implant sets according to the invention are used.
Fig . 1 zeigt das erfindungsgemäße dentale Implantatset, das mit dem Bezugszeichen 1 versehen ist und dessen Komponenten im Zustand des in den zahnlosen Bereich des Kieferknochens 5 eingesetzten Implantats 2 und des über den Implantatbereich genähten Zahnfleisches 6 gezeigt sind . Fig. 1 shows the dental implant set according to the invention, which is provided with the reference numeral 1 and whose components are shown in the state of the implant 2 inserted in the toothless region of the jaw bone 5 and of the gum 6 sewn over the implant region.
Zu den Komponenten des Implantatsets 1 gehören neben dem Implantat 2 das Knochenersatzmaterial 3 und die Membran 4. Vor Einsetzung des Implantats 2 wurde mittels eines herkömmlichen Implantatbohrers eine Kavität 9 mit einer fest definierten und präzisen Breite und Tiefe, wie auch Fig . 2 veranschaulicht, erzeugt, in der in der in Fig . 1 dargestellten Ausführungsform der Erfindung ein hälftiger Anteil des Implantats 2 eingesetzt und eingeschraubt ist. In addition to the implant 2, the components of the implant set 1 include the bone substitute material 3 and the membrane 4. Prior to insertion of the implant 2, a cavity 9 with a well-defined and precise width and depth, as well as FIG. 2, in which, in the embodiment shown in FIG. 1 illustrated embodiment of the invention, a half portion of the implant 2 is inserted and screwed.
Um das Implantat 2 herum ist ringförmig das Knochenersatzmaterial 3 angeordnet. Entgegen dem Stand der Technik befindet sich das granuläre Knochenersatzmaterial 3 nicht in einem losen körnigen, sondern in einem festen und harten Zustand, so dass das Knochenersatzmaterial 3 als ringförmiger harter Block einen zuvor für die Knochenaugmentation erzeugten und in Fig . 2 gezeigten Hohlraum 15 passgenau ausfüllt. Wie aus Fig. 2 zudem hervorgeht, ist der Hohlraum 15 bei durchbohrtem und geöffnetem Zahnfleisch 6 von einer Längsseite 16 und einer kürzeren Seite 8 begrenzt, die am oberen Ende der Kavität 9 ausgeformt ist, so dass die Kavität 9 im Gegensatz zu der herkömmlichen Praxis gewissermaßen durch den einen größeren Durchmesser als die Kavität 9 aufweisenden Hohlraum 15 eine räumliche Ausdehnung erfährt. Around the implant 2 around the bone replacement material 3 is arranged annularly. Contrary to the prior art, the granular bone substitute material 3 is not in a loose granular but in a solid and hard state, so that the bone substitute material 3 as a ring-shaped hard block one previously generated for bone augmentation and in FIG. 2 cavity 15 fills accurately. As is also apparent from Fig. 2, the cavity 15 is bounded with pierced and opened gums 6 from a longitudinal side 16 and a shorter side 8, which is formed at the upper end of the cavity 9, so that the cavity 9 in contrast to the conventional practice In a sense, by the one larger diameter than the cavity 9 having cavity 15 undergoes a spatial expansion.
Das erfindungsgemäße dentale Implantatset 1 weist zudem, wie Fig. 1 weiter zeigt, eine Membran 4 auf, die, wie das Knochenersatzmaterial 3, von fester und harter Beschaffenheit ist. Die einteilig ausgebildete Membran 4 umgibt sowohl das obere stirnseitige Ende des Implantats 2 und des Knochenersatzmateriales 3 als auch einen Teil der Wandung des als harten ringförmigen Blockes ausgebildeten Knochenersatzmateriales 3 und passt sich somit der oberen und seitlichen Außenkontur des Knochenersatzmateriales 3 bzw. des Implantats 2 an. Am unteren Ende des Teiles der Membran 4, der der seitlichen Außenkontur des Knochenersatzmateriales 3 zugewandt ist, weist die Membran ein plastisch verformbares Endstück 18 auf, um im Übergang der Membran 4 zum Knochen 5 eine optimale Adaptation zu erreichen. The dental implant set 1 according to the invention also has, as FIG. 1 further shows, a membrane 4 which, like the bone substitute material 3, is of solid and hard nature. The integrally formed membrane 4 surrounds both the upper The end face of the implant 2 and the bone substitute material 3 as well as a part of the wall of the bone replacement material 3 designed as a hard annular block and thus adapts to the upper and lateral outer contour of the bone substitute material 3 and the implant 2, respectively. At the lower end of the part of the membrane 4, which faces the lateral outer contour of the bone substitute material 3, the membrane has a plastically deformable end piece 18 in order to achieve optimum adaptation in the transition of the membrane 4 to the bone 5.
Das Implantat 2 ist lösbar mit der Membran 4 verbunden. Hierzu verfügen die Membran 4 über ein Loch 7a und das Implantat 2 über einen zum Loch 7a korrespondierenden Druckknopf 7, so dass die Membran 4 auf das Implantat 2 aufsetzbar bzw. aufsteckbar ist. Der Druckknopf 7 ist Teil einer Verschlussschraube, die integraler Bestandteil des Implantats 2 ist und mit der das obere Ende des Implantats 2 geschlossen wird . The implant 2 is detachably connected to the membrane 4. For this purpose, the membrane 4 has a hole 7a and the implant 2 via a corresponding to the hole 7a push button 7, so that the membrane 4 can be placed or plugged onto the implant 2. The push button 7 is part of a locking screw, which is an integral part of the implant 2 and with which the upper end of the implant 2 is closed.
Fig . 3 zeigt als weitere Komponente des in Fig. 1 gezeigten erfindungsgemäßen dentalen Implantationssets 1, und zwar während eines dentalen Implantationsschrittes einen Planfräser 17 in Gestalt eines Stirnplanfräsers. Der Planfräser 17 weist ein Stirnfräserelement 10 auf, das unterseitig über eine Schneide 12 verfügt. Unterhalb und mittig des Stirnfräserelementes 10 ist ein Zentrierstift 13 angeordnet, dessen Länge und Tiefe der Länge und Tiefe der in Fig. 2 gezeigten Kavität 9 entspricht. Wie aus Fig. 3 weiter hervorgeht, befindet sich oberhalb des Stirnfräserelementes 10 ein Befestigungselement 14, das die Verbindung zu einem in Fig . 3 nicht gezeigten Antrieb herstellt. Fig. FIG. 3 shows, as a further component of the dental implantation set 1 according to the invention shown in FIG. 1, specifically during a dental implantation step, a face milling cutter 17 in the form of a face milling cutter. The face milling cutter 17 has an end mill element 10 which has a cutting edge 12 on the underside. Below and in the middle of the end mill element 10, a centering pin 13 is arranged whose length and depth corresponds to the length and depth of the cavity 9 shown in FIG. As is further apparent from FIG. 3, above the face milling element 10 there is a fastening element 14, which connects to a coupling element shown in FIG. 3 produces drive not shown.
Alternativ kann statt des Planfräsers 17 auch ein Bohrfräser vorgesehen sein, der statt des Zentrierstiftes 13 über einen Bohranteil verfügt, so dass die Funktion eines Versenkbohrers und eines Planfräsers in einem Werkzeug vereint ist. Hierdurch wird vorteilhafterweise erreicht, dass die Erzeugung des in Fig . 2 gezeigten Hohlraumes 15 und die Erzeugung der in Fig. 2 gezeigten Kavität 9 in einem Arbeitsgang realisiert werden kann. Die Schritte einer dentalen Implantation, bei der das in Fig. 1 gezeigte Implantatset 1 sowie der in Fig . 3 dargestellte Planfräser 17 eingesetzt werden, veranschaulicht Fig . 4. Nachdem das Zahnfleisch 6 geöffnet und die Kavität 9 - wie in der dentalen Implantologie üblich - mittels eines herkömmlichen Implantatbohrers erzeugt worden ist, wie Fig. 4a veranschaulicht, kommt in einem nächsten und in Fig. 4b gezeigten Schritt der Planfräser 17 zum Einsatz. Der Durchmesser des Zentrierstiftes 13 des Planfräsers 17 entspricht dabei dem Durchmesser der Kavität 9. Der in Gestalt eines Stirnplanfräsers vorliegende Planfräser 17 fräst mittels der Schneide 12 den in Fig . 2 zeigten genormten Hohlraum 15. Danach wird, wie Fig . 4c verdeutlicht, das Knochenersatzmaterial 3, und zwar in Form eines ringförmigen Blockes, in den Hohlraum 15 eingesetzt. Vor Einsetzung des Implantats 2 ist das Knochenersatzmaterial 3 unverschieblich und einteilig mit dem Implantat 2 verbunden. Alternativ kann das Knochenersatzmaterial 3 auch nach dem Eindrehen des Implantats 2 in den in Fig . 2 dargestellten Hohlraum 15 eingesetzt und von dem Implantat 2 und dem Knochen 5 aufgenommen werden. Hierbei kann auch durch eine abweichende Formgebung des Knochenersatzmateriales 3 eine grundsätzliche Veränderung der finalen Knochensituation herbeigeführt werden, und zwar im Sinne einer horizontalen und/oder vertikalen Knochenaugmentation. Alternatively, instead of the face milling cutter 17, a drill bit may also be provided which has a drilling portion instead of the centering pin 13, so that the function of a countersink bit and a face milling cutter is combined in one tool. This advantageously achieves that the generation of the in Fig. 2 shown cavity 2 and the generation of the cavity 9 shown in FIG. 2 can be realized in one operation. The steps of a dental implantation, in which the implant set 1 shown in FIG. 1 as well as in FIG. 3 shown plan cutters 17 are used, FIG. 4. After the gum 6 has been opened and the cavity 9 has been produced by means of a conventional implant drill, as is customary in dental implantology, as illustrated in FIG. 4a, in a next step shown in FIG. 4b, the face milling cutter 17 is used. The diameter of the centering pin 13 of the face milling cutter 17 corresponds to the diameter of the cavity 9. The present in the form of a face milling cutter face milling 17 mills by means of the cutting edge 12 in FIG. 2 showed standardized cavity 15. Thereafter, as shown in FIG. 4c illustrates that the bone substitute material 3, in the form of an annular block, is inserted into the cavity 15. Before inserting the implant 2, the bone substitute material 3 is immovable and integrally connected to the implant 2. Alternatively, the bone substitute material 3 can also be used after the implant 2 has been screwed into the implant as shown in FIG. 2 shown cavity 15 are used and absorbed by the implant 2 and the bone 5. In this case, a fundamental change in the final bone situation can also be brought about by a different shaping of the bone substitute material 3, namely in the sense of a horizontal and / or vertical bone augmentation.
Nachdem das Implantat 2, das mit dem Knochenersatzmaterial 3 versehen ist, eingedreht worden ist, wird das Implantat 2 mit einer Verschlussschraube geschlossen, die oberseitig mit dem Druckknopf 7 abschließt (Fig . 4d). After the implant 2, which is provided with the bone substitute material 3, has been screwed in, the implant 2 is closed with a closure screw which terminates on the top side with the push button 7 (FIG. 4 d).
Wie weiter aus Fig . 4d hervorgeht, wird zur Abdeckung des Implantationsbereiches die feste und harte Membran 4 eingebracht, die mit dem Loch 7a versehen ist und auf dem leicht überkonturierten Rand nach dem "Druckknopfprinzip" aufgeknöpft wird . Im Übergang zwischen durch die Membran 4 abgedecktem Knochenersatzmaterial 3 und Knochen 5 befindet sich das plastisch verformbare Endstück 18 der Membran 4, um eine optimale Adaption, auch zum Knochen 5, zu erreichen. As further from Fig. 4d, the solid and hard membrane 4 is introduced to cover the implantation area, which is provided with the hole 7a and is unbuttoned on the slightly over-contoured edge according to the "push-button principle". In the transition between covered by the membrane 4 bone substitute material 3 and bone 5 is the plastically deformable end portion 18 of the membrane 4 in order to achieve optimal adaptation, even to the bone 5.
Schließlich wird, wie Fig . 4e zeigt, die Wunde durch Schließung und Vernähung des Zahnfleisches 6 geschlossen. Die vorliegende Erfindung beschränkt sich in ihrer Ausführung nicht auf das vorstehend angegebene bevorzugte Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten möglich, welche von der dargestellten Lösung auch bei grundsätzlich anders gearteten Ausführungen Gebrauch machen. Beispielsweise kann das Knochenersatzmaterial 3 und die Membran 4 auch aus anderen als in der Beschreibung angeführten Materialien bestehen, oder in Verbindung mit einer Direktimplantation nach Extraktion eines Zahnes, bei der der Durchmesser des leeren Zahnfachs größer als der Implantatdurchmesser ist. Finally, as shown in FIG. 4e shows the wound closed by closing and suturing the gum 6. The present invention is not limited in its execution to the above-mentioned preferred embodiment. Rather, a number of variants are possible, which make use of the illustrated solution even with fundamentally different types. For example, the bone substitute material 3 and the membrane 4 may also consist of materials other than those mentioned in the description, or in connection with a direct implantation after extraction of a tooth, in which the diameter of the empty tooth compartment is greater than the implant diameter.
