Dr. Rolf Brandau, Parkstr. 19, 26382 Wilhelmshaven Blatt Vorrichtung zur Reparatur von gebrochenen ZahnwurzelstiftenDr. Rolf Brandau, Parkstr. 19, 26382 Wilhelmshaven Blatt Device for repairing broken dental root posts
Vorrichtung zur Reparatur von gebrochenen ZahnwurzelstiftenDevice for repairing broken dental posts
Die Erfindung bezieht sich auf die bereits bekannte Methode, wurzelbehandelte und substanzgeschwächte Zähne mit Stiftaufbauten zu verstärken und zu stabilisieren. Zu diesem Zweck wird in der Regel ein individuell angefertigter oder konfektionierter Stift im Wurzelkanal zementiert oder verschraubt.The invention relates to the already known method of strengthening and stabilizing root-treated and weakened teeth with post structures. For this purpose, an individually manufactured or prefabricated post is usually cemented or screwed into the root canal.
Diese Verankerungsarten unterliegen auf Dauer einer starken Kaubelastung, wodurch es gelegentlich zu Brüchen (Frakturen) dieser Stiftaufbauten kommen kann. Das Entfernen dieser Fragmente (3) (Vorbedingung zur Aufnahme eines neuen Stiftaufbaus) stellt häufig ein nicht zu überwindendes Problem dar und führt letztlich zum Verlust des betroffenen Zahnes.These types of anchorage are subject to a strong chewing load over time, which can occasionally lead to breakages (fractures) of these post structures. The removal of these fragments (3) (a prerequisite for the insertion of a new post structure) often represents an insurmountable problem and ultimately leads to the loss of the affected tooth.
Der Erfindung liegt die Aufgabe zugrunde, die Probleme nach Stiftaufbaufraktur zu beseitigen und eine neue Vorrichtung zu schaffen, die es ermöglicht, das Wurzelstxftfragment im Wurzelkanal zu belassen und trotzdem einen neuen Stiftaufbau plazieren zu können.The invention is based on the task of eliminating the problems after a post abutment fracture and of creating a new device that makes it possible to leave the root abutment fragment in the root canal and still be able to place a new post abutment.
Erreicht wird dieses Ziel durch die röhrenförmige, zylindrische Gestaltung des Retentionsstiftes (4) des Wurzelstiftaufbaus (1). Nach Vorbereitung des Aufnahmekanals für den Hohlzylinderstiftaufbau mit Hilfe genormter Hphlfrasen (sog. Trepanbohrer) unterschiedlicher Durchmesser und Längen, wird der im Wurzelkanal belassene, abgebrochene, alte Reststift (3) vom Hohlzylinderstiftaufbau (4) teleskopartig überfaßt, verlängert und schließlich in der gewünschten Position zementiert (5) oder verschraubt.This goal is achieved by the tubular, cylindrical design of the retention pin (4) of the root post structure (1). After preparing the receiving channel for the hollow cylindrical post structure using standardized HPHL burs (so-called trephine drills) of different diameters and lengths, the broken old residual post (3) left in the root canal is telescopically grasped by the hollow cylindrical post structure (4), extended and finally cemented (5) or screwed into the desired position.
Die Verankerung der anschließend zu zementierenden Zahnkrone (6) wird dabei über die üblichen Formen des Stiftaufbaukopfes (7) gewährleistet.The anchoring of the dental crown (6) to be cemented afterwards is ensured by the usual shapes of the post abutment head (7).
Dr. Rolf Brandau, Parkstr. 19, 26382 Wilhelmshaven Blatt 3 Vorrichtung zur Reparatur von gebrochenen ZahnwurzelstiftenDr. Rolf Brandau, Parkstr. 19, 26382 Wilhelmshaven Sheet 3 Device for repairing broken dental root posts
Diese Vorrichtung zur Reparatur von gebrochenen Zahnwurzelstiften ist in der Lage, den vorzeitigen Verlust von wurzelbehandelten Zähnen zu verhindern.This device for repairing broken dental posts is able to prevent the premature loss of root-treated teeth.
Durch diese Vorrichtung erübrigt sich der sehr aufwendige und mit großen Risiken verbundene Versuch des Entfernens des Stiftfragmentes (3) aus dem Wurzelkanal (8). Durch die teleskopierende Umfassung (4) des Reststiftes (3) wird auch bei relativ kurzer Verlängerung durch den Hohlstift (4) eine zusätzliche mechanische Festigkeit erzielt. Diese Vorrichtung erlaubt es, innerhalb kürzester Zeit einen unter bisher bekannten Bedingungen kaum noch zu rettenden Zahn wieder zu erhalten, zu restaurieren und mit konventionellem Zahnersatz zu versorgen.This device eliminates the need for the very time-consuming and highly risky attempt to remove the post fragment (3) from the root canal (8). The telescopic enclosure (4) of the remaining post (3) provides additional mechanical strength even with a relatively short extension by the hollow post (4). This device makes it possible to save, restore and provide a conventional dental prosthesis in a very short time a tooth that was almost impossible to save under previously known conditions.
In der Zeichnung ist der Erfindungsgegenstand als Ausführungsbeispiel im Längsschnitt dargestellt.In the drawing, the subject matter of the invention is shown as an embodiment in longitudinal section.
