Title
(EN) ARRANGEMENT AND METHOD FOR SUPPLYING IMPLANT FIXTURES MADE PRINCIPALLY OF TITANIUM
(FR) ARRANGEMENT ET PROCEDE DE FOURNITURE D'ACCESSOIRES DE PROTHESE ESSENTIELLEMENT FAITS EN TITANE
Abstract
(EN) In an arrangement and method for supplying implant fixtures (2) made of titanium with surface structures and added bone-growth-stimulating agents or substances, the fixtures are prepared for selective use in different implantation situations. One or more first devices (9) are intended, by means of surface treatments, for example in the form of etching, shot-peening, plasma spraying and/or electrochemical treatment (so-called anodic oxidation), to supply fixtures (13-20) with different surface structures. One or more second devices (21) are intended to apply calcium phosphate layers in different dose qpplications onto implant fixtures divided into different ranges (partial ranges) (11, 12), which dose applications create layer thicknesses of the order of 1 nanometer to 3000 nanometers. In addition, as an alternative or as a complement to this, one or more third devices (22) can be provided to treat implant fixtures belonging to said range, or another range (partial range) which lacks CaP layers, by applying bone-growth-stimulating substance, for example rhBMP-2 or rhBMP-7, in different dose applications with different quantity and strength. A very high degree of selectivity is achieved in this way.
(FR) L'invention concerne un arrangement et un procédé de fourniture d'accessoires de prothèse (2) essentiellement faits en titane, présentant des structures superficielles et des agents ou substances additionnelles de stimulation de la croissance osseuse. Les accessoires sont préparés pour une utilisation sélective dans différentes situations d'implantation. Un ou plusieurs premiers dispositifs (9) sont utilisés pour fournir des accessoires (13-20) présentant différentes structures superficielles, au moyen de traitements de surface, par exemple sous forme de gravure, de grenaillage de précontrainte, de projection par plasma et/ou de traitement électrochimique (autrement appelé oxydation anodique). Un ou plusieurs seconds dispositifs (21) sont utilisés pour appliquer des couches de phosphate de calcium en différentes doses d'application sur les accessoires de prothèse divisés en différentes catégories (catégories partielles) (11, 12), lesquelles doses d'application créent des épaisseurs de couche de l'ordre de 1 à 3000 nanomètres. De plus, comme solution substitutive ou complémentaire, un ou plusieurs troisièmes dispositifs (22) peuvent être utilisés pour traiter les accessoires de prothèse appartenant à cette catégorie, ou à une autre catégorie (catégorie partielle) dépourvues de couches CaP, par application d'une substance de stimulation de la croissance osseuse, telle que rhBMP-2 ou rhBMP-7, en différentes doses d'application selon une quantité et une force différentes. On obtient ainsi un degré de sélectivité très élevé.
