AMALGOMER - an introduction

AMALGOMER

AMALGOMER Technology is the latest innovation in restorative dentistry. For the first time the strength of a classic amalgam restorative has been combined with the aesthetics and the many other advantages of Glass Ionomers. 

In short AMALGOMER is the world's first GIC to pass the ISO strength test requirements for amalgam (ISO1559:2001) as well as that of the GIC standard (ISO9917:1991).

Some of the features of AMALGOMER are as follows:

  • Designed to match the strength and durability of amalgam
  • Superb aesthetics, Industry standard shading
  • Minimal cavity preparation
  • Natural adhesion to tooth structure, Good biocompatibility
  • Hard, snappy chemical set with good working time
  • Water mix and Powder/Liquid versions available
  • No shrinkage, corrosion, expansion or thermal conductivity problems associated with other filling material
