ionomer

   Also found in: Wikipedia 0.03 sec.
ionomer (īon´mr),
n a polymer containing ion. In dentistry, ionomers are a mixture of glass and an organic acid. They are clear but vary in the amount of translucency. For this reason, their aesthetic potential does not match that of composite resins. However, ionomers are not likely to shrink or be subject to the microleakage seen in composite resins because the bonding mechanism of ionomers is an acid-base reaction rather than a polymerization reaction.
