In a method for making available a selection of spacers (42-44) for implants, four production stages are used for the greater part of the spacer selection. First, powder preparations (3-6) are chosen from among a number of possible powder preparations comprising titanium or metal powder, ceramic powder, plastic powder and/or alloy powder. In a second stage, the chosen powder preparations are placed in tools (12-15) with mould cavities for units (31-33) forming semi-finished products. In a third stage, the tools, with their powder-filled mould cavities, are placed in high-pressure-generating arrangements (21-23) in which the powders are compressed so that units with solid consistencies are formed. Finally, the units are mechanically worked to give the final shapes of the spacers, if appropriate after an intermediate stage of heat treatment in an oven (ovens).
