Abstract

Glass ionomer cements (GICs), widely used as restorative materials in dentistry, are principally composed of fluoroaluminosilicate glass powder combined with a water-soluble polyacid. The investigation of new glass compositions and polyacid components are very important to improve the mechanical properties of these cements. The objective of this work
was to prepare glass ionomers and polyacids for the use as GICs. The effects of spherical bodies, Al₂O₃ :SiO₂ ratios, replacing CaO by SrO, and ZrO₂ adding in glass powder in combination with the variation of acidic copolymer concentration on the compressive strength were investigated and discussed.
