Demand for new medical & biomaterials with elevated longevities is accelerating through the ageing of the population. The historic implantation of foreign materials into the human body is epitomised by dentistry, the most pervasive example/test-set worldwide, with an extensive list of dental solutions being transferable to orthopedics & beyond. Regardless, the rational optimisation & design of tooth/bone replacements remains an unmet challenge. Problems stem from the as-yet unresolved conflict between strength & toughness. However, glass ionomer cements show promise of resolving this material dichotomy, although their brittleness has confined use to non-load bearing applications. Our recent results on VESUVIO & NIMROD show maximal toughness attained prior to cementation completion. We propose to wrap-up this work and ensure impacting output using refined sample & experiment conditions.
