Description
Die Erfindung betrifft einen Verankerungsstift für Zahnrestaura tionen.The invention relates to an anchoring pin for dental restorations ions.
Der Halt von Restaurationen an der Zahnsubstanz wird normalerweise durch mechanische Verankerung vermittelt. Reicht die noch vorhandene Zahnsubstanz nicht zur Präparation hierfür geeigneter Retentions formen aus, so wird die Retention häufig durch Verankerungsstifte vermittelt: Sie werden zahnseitig in passend geschaffene intra kanaläre oder parapulpäre Bohrungen eingelassen und mit der heraus ragenden Seite an der Restauration befestigt.The retention of restorations on the tooth structure is normal mediated by mechanical anchoring. If the still existing one Tooth substance not suitable for the preparation of suitable retention shape, so retention is often through anchoring pins conveyed: They are placed on the tooth side in suitably created intra canal or parapulpary holes inserted and with the out projecting side attached to the restoration.
Die Stiftverankerung von Zahnrestaurationen erfolgt heute üblicherweise mit Metallstiften. US 44 49 937 schlägt zwar auch die Verwendung von Stiften aus Kunststoff im Sinne von Plastik ("plastic material") vor, doch wurde nie über deren wirklichen Einsatz berichtet. Sämtlichen bekannten Kunststoffen im Sinne von "plastic material", d. h. mit Formgebung im plastischen Zustand, fehlt es an der hierfür erforderlichen mechanischen Festigkeit.Dental restorations are anchored in the pin today usually with metal pins. US 44 49 937 also suggests that Use of plastic pens in the sense of plastic ("plastic material "), but their actual use has never been reported. All known plastics in the sense of "plastic material", d. H. With Shaping in the plastic state, the necessary is missing mechanical strength.
Die Befestigung der Verankerungsstifte an der verbliebenen Zahnsubstanz - auch an Implantaten - geschieht durch Einschrauben oder -zementieren der Verankerungsstifte.The attachment of the anchoring pins to the remaining tooth structure - also on Implants - done by screwing or cementing the Anchor pins.
Im Falle der intrakanalären Verankerung kommt diesen - dann auch Wurzel- oder Stabilisierungsstifte genannten - Stiften außerdem die Funktion der mechanischen Stabilisierung der geschwächten devitalen Wurzel zu. (1, 2).In the case of intracanal anchoring, these pins, which are also called root or stabilization pins, also have the function of mechanically stabilizing the weakened devital root. ( 1 , 2 ).
Außerhalb des Gebiets der Zahnrestauration verdrängen seit Jahr zehnten faserverstärkte Kunststoffe Metalle aus dem Bereich mechanisch beanspruchter Formteile (3).Outside the field of tooth restoration, fiber-reinforced plastics have been displacing metals from the area of mechanically stressed molded parts ( 3 ) for decades.
Verschiedene Systeme faserverstärkter Kunststoffe wurden bereits ohne nennenswerte Verträglichkeitsprobleme auch in der Mundhöhle längere Zeit getragen (4, 5).Various systems of fiber-reinforced plastics have been worn in the oral cavity for a long time without any notable compatibility problems ( 4 , 5 ).
Metall ist vollkommen lichtundurchlässig.Metal is completely opaque.
Deshalb stören metallische Anteile einer Zahnrestauration die natürliche Transluzenz und beeinträchtigen daher das natürliche Aussehen des Zahns, auch wenn sie zahnfarben abgedeckt werden. Therefore, metallic parts of a tooth restoration disrupt the natural translucency and therefore impair the natural Appearance of the tooth, even if it is covered in tooth color.
Der Erfindung liegt die Aufgabe zugrunde, einen Verankerungsstift für Zahnrestaurationen aus einem Material von nicht nur ausreichender Festigkeit und Körperverträglichkeit, sondern darüberhinaus zahn ähnlicher Farbe und Transluzenz herzustellen, der eine wirtschaft liche und dauerhafte Zahnrestauration ermöglicht.The invention has for its object an anchoring pin for tooth restorations made of a material of not only sufficient Firmness and body tolerance, but also tooth to produce similar color and translucency that is economical Liche and permanent tooth restoration possible.
Die Aufgabe wird durch antragsgemäße Verankerungsstifte gelöst. In ihren mechanischen Eigenschaften jenen aus Metall ebenbürtig sind sie preiswert in zahnähnlicher Transluzenz und Farbe herstellbar. Ihre Befestigung im nach erhärteter apikaler Wurzelkanalfüllung passend aufbereiteten Kanal bzw. in passend präparierten parapul pären Bohrungen erfolgt vorzugweise nach deren Konditionierung mit Dentin-Haftvermittler mit Kunststoff, mit dem nach dem Einführen der Verankerungsstifte auch gleich die Restauration erfolgen kann.The task is solved by anchoring pins according to the application. In terms of mechanical properties, it is on a par with metal they are inexpensive to produce in tooth-like translucency and color. Your attachment in after hardened apical root canal filling suitably prepared canal or in suitably prepared parapul Pairs of holes are preferably made after their conditioning Dentin bonding agent with plastic, with which after insertion the anchoring pins can also be used for the restoration.
Durch die zahnähnliche Farbe und Transluzenz der Verankerungsstifte wird eine Voraussetzung geschaffen, auch der ganze Restauration zahnähnliches Aussehen zu verleihen.Due to the tooth-like color and translucency of the anchor pins a prerequisite is created, including the entire restoration to give a tooth-like appearance.
Außerdem lassen sich stiftverankerte Restaurationen schnell, preis wert und dauerhaft erstellen.In addition, restorations anchored in the pen can be quickly and cheaply priced worth and create permanently.
Die Zeichnung zeigt einen intrakanalär und einen parapulpär zu verwendenden antragsgemäßen Verankerungsstift.The drawing shows an intracanal and a parapulpär to anchoring pin according to the application.
