Glass Ionomer Fillings

Glass ionomer fillings are a finely ground glass mixture, embedded in a plastic matrix, which are exceptionally difficult to manufacture. Professionally, this material is known as “white gold”, because one gram of it is more expensive that one gram of high-quality dental gold alloy. The filling material is also known as composite and it is especially suited to the treatment of small defects or certain types of esthetic tooth reshaping. The excellent color stability is also an advantage. The use of special, complex dentine adhesive binding techniques ensures long-term join stability and durability. Previously, composite materials have found only limited use in the area of the molars and premolars due to the grinding and chewing pressure that they would be exposed to.
