PASTE:PASTE GLASS IONOMER CEMENT SYSTEM AND METHOD

摘要

The present invention provides a multiple part photocurable ionomeric cement system. The first part is an aqueous paste comprising a photocurable ionomer having sufficient pendent ionic groups to undergo a setting reaction in the presence of a reactive filler and water and sufficient pendent polymerizable groups to enable the resulting mixture to be cured by exposure to radiant energy. The second part is an organic paste comprising reactive filler. This system provides ionomeric cements exhibiting excellent strength and opacity properties.
