Abstract
An implant is produced with an open-celled structure at least partly covering its surface. The method uses a positive pattern having a basic pattern with particles bonded to it, the particles covering the areas of the pattern which correspond to the structured surface areas of the implant. The method uses the usual steps of conventional lost positive casting techniques. Importantly, the particles have a base with four to eight pins extending radially from its surface with at least three being connected to the basic pattern (e.g., by adhesive).
