ChemFil® Superior is a fast-setting glass-ionomer restorative material consisting of a blend of alumino silicate glass and polyacrylic acid. The powder is mixed with distilled water to produce a filling material which adheres to dentine and enamel producing tight- ly sealed, strong and aesthetic restorations.
ChemFil Superior is available in 7 shades: L, LY, LYG, LG, DG, DY, GB.
ChemFil Superior complies with the requirements of ISO 9917-1:2003 for glass-iono- mer restorative materials.
In all classes of cavity this may be kept to the minimum required for caries removal. Preparation of mechanical retention is not needed except when restoration is liable to be subjected to high displacement forces.
Surface cleanliness is paramount for the development of adhesion. Clean freshly cut enamel and dentine with water spray and air-dry. Where no cavity preparation is neces- sary, clean the tooth surface with rubber cup and pumice or a prophy paste (Zircate® or Nupro®). Wash thoroughly with water spray and air-dry.
In deep cavities cover the dentine closest to the pulp with a calcium hydroxide liner (Dycal®) leaving the rest of the cavity floor and walls free for chemical bonding with ChemFil Superior.
For surface conditioning, ChemFil Tooth Cleanser or ChemFlex™ Liquid may be used. Apply ChemFil Tooth Cleanser or ChemFlex Liquid to the cavity surface and allow it to remain for 15 seconds. Wash off and remove rinsing water, leaving a moist surface.
ChemFil Superior is available in 7 shades. Shade selection is made with the shade guide supplied. As the translucency and colour of glass-ionomer cements change dur- ing the first hours after placement, the shade guide represents the final shade of the restoration.
