In the last 20 years, dental materials scientists have worked diligently to produce glass-ionomer cement systems that overcome the three chief disadvantages of this class of materials: difficult handling properties, poor resistance to surface wear, and poor resistance to fracture.
They have produced products that are so improved that these major disadvantages have been significantly reduced. Such improvements are bound to continue and glass-ionomer cement formulations will gain even more importance in restorative dentistry, preventive dentistry, and orthodontics. (DentalAegis)
