Enhanced bioactivity of glass ionomer cement by incorporating calcium silicates [PDF]

open access: yesBiomatter, 2016
Glass ionomer cements (GIC) are known as a non-bioactive dental cement. During setting the GIC have an acidic pH, driven by the acrylic acid component. It is a challenge to make GIC alkaline without disturbing its mechanical properties. One strategy was to add slowly reacting systems with an alkaline pH.

Apatite bone cement reinforced with calcium silicate fibers

open access: yesJournal of Materials Science: Materials in Medicine, 2014
Several research efforts have been made in the attempt to reinforce calcium phosphate cements (CPCs) with polymeric and carbon fibers. Due to their low compatibility with the cement matrix, results were not satisfactory. In this context, calcium silicate fibers (CaSiO3) may be an alternative material to overcome the main drawback of reinforced CPCs ...
