Definitions

  • the invention relates to a model carrier for articulators for emulating the position and the movement sequence of the rows of teeth of the upper and lower jaw for the manufacture of dental prostheses
  • the plate-shaped model carrier having a recess, preferably in the central region has a fastening screw for receiving the base plate or the counter plate of the articulator and screwing it from below or from above through the base plate or the counter plate, and positioning means are arranged on the top and / or bottom of the model carrier which clearly reproducible Ensure the position of the model carrier on the one hand with respect to the base plate or the counter plate of the articulator and on the other hand of the model with respect to the model carrier.
  • articulators A wide variety of articulators are known. For example, such are described in AT-PS 371 333, in CH-PS 249 969 and in DE-OS 30 05 524. Common to these articulators is that they are used in conjunction with model plates and so-called Spli cast metal supports be used.
  • the model plates have a threaded hole in the middle, are usually designed as circular disks and have several continuous recesses which expand towards the bottom.
  • Another embodiment of these model plates instead of the continuous recesses widening downwards carries upwardly projecting threaded pins.
  • Both the mentioned recesses and the multiply arranged threaded pins on the top serve to firmly and securely anchor the connection aces with which the tooth replacement part is attached to the model plate, because this connection must be made during the entire machining ⁇ the time of the dental prosthesis must be maintained Once the dental prosthetic item has been completed, the binding compound separated and this is usually thrown away together with the model plate anchored to it.
  • Splitcast metal carriers are those model carriers on which the tooth replacement part is repeatedly detachably fastened. This releasable fastening has the advantage that it can be solved by the model carrier in the case of complex and complex work on the tooth replacement part.
  • These splitcast metal supports have a ferromagnetic plate on their surface, as well as groove-like or groove-like depressions.
  • a small, disc-like, permanent magnet, which is received by a sleeve, is attached to the denture part via the connecting compound and applies the necessary holding force when the denture part is placed on the splitcast metal carrier.
  • the groove-like and groove-like depressions serve for clearly repeatable positioning between the model carrier and the tooth replacement part.
  • This splitcast metal carrier can be used repeatedly and repeatedly because the separation between the dental prosthetic item and the spli cast metal carrier is simple, as already explained above. As a rule, with this type of connection, only the metallic sleeve, which holds the disk-like magnet, is thrown away together with the connecting compound.
  • the invention now aims to design the model carrier so that it can be used repeatedly, regardless of whether it is used in the sense of a splitcast metal carrier or in the sense of a model plate, as explained in more detail above.
  • the invention proposes that the recess in the model carrier for receiving the fastening screw be designed as a push-through hole which completely penetrates the model carrier and whose diameter is equal to or is slightly larger than the outer diameter of the fastening screw and a threaded sleeve can be screwed onto the fastening screw, which at its outer end has either a flat flange or an upwardly diverging conical or pyramid-shaped attachment and, when the threaded sleeve is screwed on, the Flange or the approach rests positively on the top of the model carrier.
  • Figure 1 shows a model carrier in plan view.

  • This recess 6 starts from the top 5 of the model carrier 1. On the bottom
  • two blind bores 7 and ⁇ are provided which, with respect to the central through bore 4, show different distances.

  • the fastening screw 11 with which the model carrier 1 and the base plate or the counter plate 9 of the articulator are connected to one another, is shown as the bottom component in the exploded view according to FIG. 4.
  • This fastening screw 11 has a knurled head 12 and a threaded shaft 13 which is no longer than the sum of the thickness of the model carrier 1 and the base or counter plate 9 of the articulator.
  • the outer diameter d of the threaded shaft 13 is somewhat smaller than the diameter D of the through bore 4 of the model carrier 1.

Abstract

Pour pouvoir utiliser une seule et même plaquette porte-modèle (1) pour articulateurs permettant de reproduire la position et le déroulement du mouvement des dentures des maxillaires supérieur et inférieur pour la fabrication de prothèses dentaires et cela aussi bien comme plaque d'empreinte que comme support métallique Splitcast, la plaquette porte-modèle (1) possède un perçage central (4) dans lequel, se dresse, lors de l'emploi conformément aux prescriptions une vis de fixation (11), qui, de son côté, traverse la plaque de base ou la contre-plaque (9) de l'articulateur. Le diamètre (D) du perçage (4) est supérieur au diamètre extérieur (d) de la vis de fixation (11). Des douilles filetées (15 ou 15') sont prévues pour raccorder la plaquette porte-modèle (1) avec la plaque de base ou la contre-plaque (9) de l'articulateur. L'une des douilles filetées (15) porte à son extrémité une bride plate (16), l'autre porte un épaulement (17) en forme de cône s'évasant vers le haut. Ce dernier sert d'élément contre-dépouillé pour l'ancrage de la masse de liaison avec laquelle la prothèse est fixée sur la plaquette porte-modèle (1). La bride (16) de la douille filetée (15) en revanche sert de pièce d'arrêt à un aimant discoïde noyé dans la masse de liaison. Après achèvement de la prothèse, la plaquette porte-modèle (1) peut être réutilisée, que la prothèse ait été fixée à la plaquette porte-modèle par l'intermédiaire de la masse de liaison de manière permanente ou au contraire de manière amovible par l'intermédiaire de l'élément d'arrêt magnétique.
