Abstract

L’invention concerne un procédé de fabrication d’un dispositif médical sur mesure pour restaurer l’anatomie occlusale d’une dent, comprenant les étapes suivantes : acquerir l’anatomie initiale de la dent à restaurer par empreinte conventionnelle ou par empreinte numérique par scannage intra-oral,importer l’empreinte numérique ou un scan de l’empreinte conventionnelle,concevoir la zone à restaurer par biogénérie ou par modélisation numérique manuelle, de manière à obtenir un modèle numérique de ladite zone,exporter le modèle numérique obtenu pour réaliser, en image miroir, le modèle numérique du tampon,compléter le modèle numérique du tampon par adjonction d’une ou plusieurs ailettes de stabilisation configurées pour, en usage, se plaquer sur les tissus résiduels de la dent à restaurer ou pour épouser les structures dentaires adjacentes à ladite dent, et verrouiller ledit tampon en position,fabriquer, par Conception Fabrication Assistée par Ordinateur (CFAO), le dispositif dans un matériau rigide transparent par usinage ou par impression, ledit dispositif comprenant un corps correspondant au négatif de la dent à reconstituer et formant le tampon permettant l’obtention d’une anatomie occlusale adéquate par estampillage, un manche de préhension.The invention relates to a method of manufacturing a tailor-made medical device for restoring the occlusal anatomy of a tooth, comprising the following steps: acquiring the initial anatomy of the tooth to be restored by conventional impression or by digital impression by scanning intra-oral, import the digital impression or a scan of the conventional impression, design the area to be restored by bioengineering or by manual digital modeling, so as to obtain a digital model of said area, export the digital model obtained to produce, in mirror image, the digital model of the pad, completing the digital model of the pad by adding one or more stabilizing fins configured to, in use, be pressed against the residual tissues of the tooth to be restored or to match the adjacent dental structures to said tooth, and lock said pad in position, manufacture, by Computer Aided Manufacturing Design (CAD/CAM), the device in a transparent rigid material by machining or by printing, said device comprising a body corresponding to the negative of the tooth to be reconstituted and forming the stamp allowing adequate occlusal anatomy to be obtained by stamping, a gripping handle.
