One of the supreme advantages of the glass-ionomer cement is its ability to establish a true, permanent bond to hydroxyapatite even under the moist conditions of cavities close to the gingival margin. ChemFil Superior is at the forefront of glass-ionomer technology and links outstanding adhesion to superior handling characteristics and pleasing aesthetics. It combines a smooth and non-sticky consistency for easy application with a high powder loading for extra mechanical strength.

ChemFil Superior offers both sufficient working time and most rapid set possible. It is the ideal restorative material for: 

- Cavities with margins mainly in dentine 
- Cavities close to the gingival margin, where moisture control is not possible
- Cases where cavity preparation and/or the acid etch technique are not accepted

ChemFil Superior is available in a hand-mixed format and combines fast setting characteristics with a smooth, non-sticky consistency that is quite unique for a glass-ionomer.
