Abstract

The device has an opaque pattern (1) corresponding to replica of interior of an implant transfer, where the pattern has the taper between 0 to 35 degrees. A false implant stump (5) is positioned on the pattern, and a space is provided between a base of the pattern and a false stump (5). The space is filled by a paste to be modeled or a preform (2) permitting to give adapted shape to an occlusal surface of the false implant stump.

Description

-1- La présente invention concerne un dispositif destiné à scanner les -1- The present invention relates to a device for scanning

faux moignons implantaires dans le domaine de la prothèse dentaire, afin de les usiner sur des systèmes de type cfao(conception/fabrication assistée par ordinateur). implant abutments in the area of ​​the dental prosthesis to be machined on the cam-like systems (design / computer aided manufacturing).

Traditionnellement les faux moignons implantaires ne sont pas réalisables sur ce type de système cfao, système composé en général d'un scanner numérique permettant de numériser les empreintes soit de façon optique par laser et/ou caméra haute définition, soit de façon mécanique avec un palpeur ; Traditionally implant abutments are not feasible for this type of cam system, system composed generally of a digital scanner for scanning the fingerprint is optically by laser and / or high-definition camera, or mechanically with a feeler ; ainsi q'un ordinateur permettant la conception virtuelle des pièces et d'une station d'usinage permettant de réaliser les pièces virtuelles dans n'importe quel type de matériaux. thus q computer for the virtual design of parts and a processing station for performing virtual rooms in any type of material. Ce qui oblige les utilisateurs à acheter leurs pièces prothétiques à des entreprises extérieures qui n'offrent pas forcement une bonne adaptation morphologique, car les pièces ainsi fournies sont le plus souvent de forme standard et il est nécessaire de les retravailler. This forces users to buy their prosthetic components to outside companies that do not necessarily provide good morphological adaptation, as well furnished rooms are mostly standard form and it is necessary to rework. De plus ces entreprises d'usinages ne proposent que certains types d'implants. Moreover these machining companies only offer certain types of implants. Une autre façon de réaliser ces faux moignons est de les couler avec tous les inconvénients que cela comporte : - Un matériau qui n'est pas forcement biocompatible. Another way to achieve these abutments is to sink with all the disadvantages that entails: - a material that is not necessarily biocompatible. -Des défauts d'état de surface liés à la coulée avec une précision et une reproductibilité moindre que celle obtenue à l'usinage par système cfao. -the surface condition defects related to the casting with a precision and less reproducibility than that obtained by machining system cam.

Le dispositif selon l'invention permet de remédier à ces inconvénients. The device of the invention overcomes these drawbacks. Il comporte en effet selon une première caractéristique, une maquette opaque, de préférence de couleur claire, moulée ou tournée dans différents matériaux de préférence non réfléchissants tel que zircone, métal sablé, époxy, résine, plastique ou autre et pouvant intégrer une certaine conicité (0 à 35 degrés). It comprises in effect according to a first feature, an opaque model, preferably light-colored, molded or turned in different materials of non-reflective preferably as zirconia, sandblasted metal, epoxy, resin, plastic or the like and may incorporate some conicity ( 0 to 35 degrees). La maquette étant la réplique de l'intérieur du transfert d'implant il est donc possible de par ce fait de travailler sur un grand nombre de types d'implants. The model is a replica of the interior of the transfer implant it is possible by this fact to work on many types of implants. 2906129 -2- Le faux moignon implantaire sera mis en forme suivant le travail habituel du prothésiste dentaire puis positionné sur la maquette de balayage. 2906129 -2- abutment implant will be shaped according to the usual working of the dental technician and then positioned on the scanning model. L'espace constitué entre la base de la maquette et du faux 5 moignon sera comblé par de la pâte à modeler ou une préforme ce qui permettra au final de donner la forme de la face occlusale du faux moignon implantaire. The space formed between the base of the model and the false stump 5 will be filled by the dough or preform which will ultimately give the shape of the occlusal surface of the implant abutment. La maquette ainsi obtenue peut être centrée et montée par des tiges métalliques dites broches sur un socle mat non 10 réfléchissant fixé dans le scanner et permettant ainsi sa manipulation entre les opérations de balayage. The model thus obtained can be centered and mounted by metal rods said pins on a non-reflective base mat 10 set in the scanner and allowing its handling between scanning operations. Une fois cette pièce parfaitement réalisée il devient possible d'usiner des faux moignons implantaires d'une grande précision, dans les matériaux les plus pointus tel que, Zircone, Titane, 15 Zirconia, alumina, alliages, vitrocéramique ou autre et sur un grand nombre de types d'implants permettant la réalisation de faux moignons aux morphologies adaptées et non de formes standards à retravailler. Once this piece perfectly realized it becomes possible to machine abutments implant of a high accuracy, in the most advanced materials such as, zirconia, titania, 15 Zirconia, alumina, alloys, ceramic or the like and a large number types of implants to achieve abutments adapted to the morphology and non-standard forms of rework. Selon les modes particuliers de réalisation : 20 la maquette de balayage peut avoir une conicité entre 0 et 35 degrés pour faciliter l'usinage. According to particular embodiments: the scanning model 20 may have a taper between 0 and 35 degrees to facilitate machining. une patte à modeler ou une préforme peuvent constituer une base adaptée pour déterminer la face occlusale du faux moignon implantaire. a tab shape or a preform can be a base adapted to determine the occlusal surface of the implant abutment. 25 la maquette peut être centrée et montée avec broches sur un socle amovible de façon à pouvoir la manipuler. The model 25 may be centered and mounted with pins on a removable base so as to be able to handle. Le dessin annexé illustre l'invention : La figure 1 représente en coupe, le dispositif de l'invention. The accompanying drawing illustrates the invention: Figure 1 shows in section, the device of the invention.

30 En référence à ces dessins, le dispositif comporte une maquette(1) incluant une certaine conicité dont la base en contact avec le socle mat (4) est munie de tiges métalliques (3) dites broches. 30 Referring to these drawings, the device comprises a model (1) including a certain conicity, the base in contact with the mat base (4) is provided with metal rods (3) said pins. Elle est aussi munie d'une préforme ou pâte à modeler (2) venant terminer la forme du faux moignon implantaire (5). It is also provided with a preform or dough (2) from the finish shape of the implant abutment (5).
