Abstract
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.
