In this paper, we report on the enhanced strength of glass ionomer cement (GIC) by using the process of pre acid-base reaction and spray drying in glass preparation. The pre acid-base reaction was induced by prior mixing of the glass powder with poly(alkenoic acid). The weight ratios of glass powder to poly(alkenoic acid) were varied to investigate the extent of the pre acid-base reaction of the glass. The effect of the spray drying process which produced spherical glass particles on cement strength was also studied and discussed. The results show that adding 2%-wt of poly(alkenoic acid) liquid in the pre-reacted step improved cement strength. GICs prepared using a mixture of pre-reacted glass with both spherical and irregular powders at 60:40 by weight exhibited the highest compressive strength at 138.64±7.73 MPa. It was concluded that glass ionomer cements containing pre-reacted glass with mixed glass morphology using both spherical and irregular forms are promising as restorative dental materials with improved mechanical properties and handling characteristics.

“…AMGCs are triphasic materials composed of fluorapatite (Ca10(PO4)6F2) and mullite (Si2Al6O13) in a residual glass matrix [5]. Fluorapatite is bioactive and promotes cellular attachment [6,7] and the presence of fluoride ions promotes bone regeneration [8].…”

“…Glass ionomer bone cement may be an alternative material in this area for reconstruction of selected fractures or defects. it has been shown in many experimental and clinical studies that glass ionomer bone cements have a high affinity and good adhesivenes to bone (7,9,14). the only question that remains is how the surrounding tissue reacts to Gic in this area.…”
