Influence of composition on fingerprint dynamics in cement-forming bioactive glasses.

Abstract: Glass Ionomer Cements (GICs) - 2nd biggest earner of the British Technology Group - have found numerous applications in dentistry/medicine. The EU Commission in its advocating Hg-free dental/medical materials specifically highlight GICs as an excellent option; albeit currently too brittle for use as permanent implants. Lack of understanding of the influence of composition of the glass on its properties hinders materials optimisation. We look now to fill this void - our ab intio molecular dynamics determinations identify Al-centres as being candidate controllers of flexibility/rigidity; in agreement with historic predictions. We propose to quantitatively characterise fingerprint dynamics of GIC glasses - helping resolve the bases of the composition-dependent dynamics, and their potential for promoting rigidity/flexibility at Al-centre, in the bulk and eventually the cements they form.
