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 lesThe 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 c. f. a. o.(conception/fabrication assistée par ordinateur).  false implant stumps in the field of dental prosthesis, in order to machine them on type c systems. f. at. o. (Computer Aided Design / Manufacturing).

Traditionnellement les faux moignons implantaires ne sont pas réalisables sur ce type de système c.f.a.o., système composé en général d'un scanner numérique permettant de numériser les empreintes soit de façon optique par l.a.s.e.r. et/ou caméra haute définition, soit de façon mécanique avec un palpeur ; 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. 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. De plus ces entreprises d'usinages ne proposent que certains types d'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. -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 c.f.a.o..  Traditionally false implant stumps are not feasible on this type of system c.f.a.o., system generally composed of a digital scanner for digitizing fingerprints either optically by l.a.s.e.r. and / or high-definition camera, either mechanically with a probe; as well as a computer allowing the virtual design of the parts and a machining station allowing to realize the virtual parts in any type of materials. This forces users to buy their prosthetic parts from outside companies that do not necessarily offer a good morphological adaptation, because the parts thus provided are usually standard shape and it is necessary to rework them. In addition, these machining companies offer only certain types of implants. Another way to make these false stumps is to sink them with all the disadvantages that this entails: - A material that is not necessarily biocompatible. Surface-related defects related to casting with a precision and a reproducibility less than that obtained with the machining by system c.f.a.o ..

Le dispositif selon l'invention permet de remédier à ces inconvénients. 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). 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. 2906129 -2- Le faux moignon implantaire sera mis en forme suivant le travail habituel du prothésiste dentaire puis positionné sur la maquette de balayage. 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. 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. 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. Selon les modes particuliers de réalisation : 20 la maquette de balayage peut avoir une conicité entre 0 et 35 degrés pour faciliter l'usinage. une patte à modeler ou une préforme peuvent constituer une base adaptée pour déterminer la face occlusale du faux moignon implantaire. 25 la maquette peut être centrée et montée avec broches sur un socle amovible de façon à pouvoir la manipuler. Le dessin annexé illustre l'invention : La figure 1 représente en coupe, le dispositif de l'invention.  The device according to the invention overcomes these disadvantages. It comprises in fact according to a first feature, an opaque model, preferably light in color, molded or turned in different materials preferably non-reflective such as zirconia, sandblasted metal, epoxy, resin, plastic or other and can incorporate a certain taper ( 0 to 35 degrees). Since the model is the replica of the inside of the implant transfer, it is therefore possible to work on a large number of implant types. The false implant abutment will be shaped according to the usual work of the dental technician and positioned on the scan model. The space formed between the base of the model and the false abutment will be filled with modeling clay or a preform which will ultimately give the shape of the occlusal surface of the false implant stump. The model thus obtained can be centered and mounted by metal rods called pins on a non-reflecting matte base fixed in the scanner and thus allowing its handling between scanning operations. Once this piece is perfectly made it becomes possible to machine false implant abutments of great precision, in the most pointed materials such as, Zirconia, Titanium, Zirconia, alumina, alloys, glass-ceramic or other and on a large number types of implants allowing the realization of false stumps with adapted morphologies and not standard forms to rework. According to particular embodiments: the scanning model may have a taper between 0 and 35 degrees to facilitate machining. a modeling lug or a preform may constitute a suitable base for determining the occlusal surface of the false implant stump. 25 the model can be centered and mounted with pins on a removable base so that it can be manipulated. The attached drawing illustrates the invention: FIG. 1 represents 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. Elle est aussi munie d'une préforme ou pâte à modeler (2) venant terminer la forme du faux moignon implantaire (5).With reference to these drawings, the device comprises a model (1) including a certain taper whose base in contact with the mat base (4) is provided with metal rods (3) said pins. It is also provided with a preform or modeling clay (2) to complete the shape of the false implant stump (5).
