Screw pullout test setup. Workflow of specimen preparation for pullout tests: (a) In case of the drillable bone substitute, screws could be manually drilled into the cement. In all other cases screws were embedded in silicon rubber molds, in which cement was poured. (b) The cylindrical probes were then analyzed via X-rays to ensure equal screw placement, (c) prior to applying a tensile load with a custom-made test device for screw pullout.
