Abstract

The method involves importing planning data for an implant and a dataset of a three dimensional (3D)-model. An implant axis is constructed with depth limit on the 3D model. The imported dataset is exported. A physical jaw model is manufactured, and the jaw model is drilled with a drilling device. A drill core is inserted into the jaw model. A malleable, resilient and hardening drilling template material e.g. hardening plastic material and light-hardening plastic material, is applied on the jaw model with the drill core. A drilling collet is cast, and the drill core is removed.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Anfertigung einer Bohrschablone nach dem Oberbegriff des Hauptanspruches. Ein derartiges Verfahren ist bekannt.The invention relates to a method for producing a drilling template according to the preamble of the main claim. Such a method is known.

Durch die EP0756735A1 ist es bekannt, von einem Körperteil ein medizinisches Modell auf der Basis von digitalen Bildinformationen mittels der RP-Technik herzustellen. Dabei werden digitale Bildinformationen in ein Basismodell umgesetzt, das ein künstliches, funktionales Element, z. B. eine Führung für einen Bohrmeisel aufweist. Dabei kann die digitale Bildinformation für die Erstellung des künstlich, funktionalen Elementes so bearbeitet werden, dass es digital konstruierbar ist.By the EP0756735A1 It is known to produce from a body part a medical model based on digital image information by means of the RP technique. This digital image information is converted into a basic model that an artificial, functional element, eg. B. has a guide for a drill bit. In this case, the digital image information for the creation of the artificial, functional element can be edited so that it can be digitally constructed.

Auch ist es bekannt, digitale Bilddaten während der Vorbereitung einer chirurgischen Operation zu verändern. So ist es beispielsweise möglich, die Position und Richtung eines Implantats auf den Bildern zu bestimmen oder chirurgische Eingriffe zu simulieren.It is also known to alter digital image data during the preparation for a surgical operation. For example, it is possible to determine the position and direction of an implant on the images or to simulate surgical procedures.

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Methode weiter zu entwickeln und ein Verfahren zur Anfertigung einer Bohrschablone zu schaffen, das mit wenigen Verfahrensschritten zu einer präzisen Bohrschablone führt. Diese Aufgabe wird gemäß der Erfindung gelöst durch die kennzeichnenden Merkmale des Hauptanspruches. Eine vorteilhafte Weiterbildung des Gegenstandes des Anspruches 1 ergibt sich aus den Merkmalen der Unteransprüche 1 sowie aus der Beschreibung und der Zeichnung.The invention has for its object to further develop the known method and to provide a method for making a surgical template, which leads to a precise surgical template with a few steps. This object is achieved according to the invention by the characterizing features of the main claim. An advantageous development of the subject matter of claim 1 results from the features of the subclaims 1 and from the description and the drawing.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der beifolgenden Beschreibung näher erläutert. Es zeigen:An embodiment of the invention is illustrated in the drawing and explained in more detail in the appended description. Show it:

1 einen PC 1 für den Import von Planungsdaten anhand von entsprechenden Koordinaten, ferner für den Import eines Datensatzes von einem 3D-Modell und für die Zusammenführung der Implantat-Planungsdaten mit dem Datensatz des 3D-Modells, dem sogenannten „matchen”. Auf dem PC 1 wird dann auf dem 3D-Modell die Implantatachse 2 konstruiert und mit einer Tiefenbegrenzung in Form eines Tiefenanschlages 3 (vgl. 46) versehen. Schließlich wird der ermittelte Datensatz exportiert. 1 a PC 1 for the import of planning data on the basis of corresponding coordinates, furthermore for the import of a data set from a 3D model and for the combination of the implant planning data with the data record of the 3D model, the so-called "matchen". On the PC 1 then becomes the implant axis on the 3D model 2 constructed and with a depth limit in the form of a depth stop 3 (see. 4 - 6 ) Mistake. Finally, the determined record is exported.

Ferner das Bohren in das Kiefermodell mit einer nicht gezeigten Bohrmaschine) 2 shows, as a sixth method step, a physical jaw model (lower jaw) produced by means of an RP method. Further, drilling into the jaw model with a drilling machine, not shown)

4 Das Platzieren des Tiefenanschlages 3 in das Kiefermodell 4. 4 Placing the depth stop 3 in the jaw model 4 ,

5 Das Einbringen einer Bohrhülse 5. 5 The introduction of a drill sleeve 5 ,

6 Stellt Bohrhülse 5 und Tiefenanschlag 3 in endgültiger Lage dar. 6 Represents drill sleeve 5 and depth stop 3 in a definitive position.

7 Zeigt das Aufbringen von formbarem, elastischem und aushärtendem Bohrschablonen-Material (Kunststoff) auf das Kiefermodell 4. samt Bohrkern 6. Die Bohrhülse 5 wird eingegossen. 7 Shows the application of malleable, elastic and hardening drilling template material (plastic) on the jaw model 4 , complete with drill core 6 , The drill sleeve 5 is poured.

8 Schließlich wird der Bohrkern 6 (Hilfsteil) entfernt und die Bohrschablone mit eingegossener Bohrhülse 5 ist fertig. Sie ist vom Kiefermodell separiert. 8th Finally, the core is 6 (Auxiliary part) removed and the drilling template with cast-in sleeve 5 is finished. It is separated from the jaw model.

Es ist noch zu bemerken, dass der verwendete Kunststoff ein aushärtender Kunststoff ist und lichthärtend ist.It should also be noted that the plastic used is a thermosetting plastic and is light-curing.

Der Tiefenanschlag 3 ist für einen Bohrer bestimmt, der mit einem Kragen versehen ist und der mit Hilfe des Kragens in seinem Arbeitshub begrenzt ist, um den Kiefer des Patienten mit Sicherheit nicht zu durchbohren.The depth stop 3 is intended for a drill, which is provided with a collar and which is limited by means of the collar in his working stroke, so as not to pierce the jaw of the patient with certainty.
