A study in radiopaque polymeric materials
… strength. Toxicologically the zinc-containing materials are satisfactory and though zinc is extracted at a measurable rate in an aqueous system, this is very small and should be acceptable over the life of a denture. In other respects the composite is quite satisfactory and though a marketable …
