Considering both the demands of sufficient mechanical strength for loaded bone implants as well as prevention of the stress shielding phenomena, open-cell metal foams are reinforced with strong but resorbable mineral bone cement. Titanium- and iron-based composites with highly prolonged stress resilence and favorable cytoxicity are achieved. Resorption of mineral phase gradually decreases the implant stability while concurrently raising the bone regeneration through mechanical stimulation. Furthermore, iron-based composites are intended to be resorbed and corrode consecutively. Thus, a temporary bone implant can be obtained.en620journal article
