Permlastic® is a polysulfide, condensation-cured, elastomeric impression material in three viscosities.
Regular Permlastic is recommended for partial- or
full denture impressions because it has a high degree of flow that will
register the finest detail. While usually used in single-mix, it can be
used with Light-Bodied Permlastic for crown and bridge impressions. It
will not tear when being removed from undercuts.
Light-Bodied Permlastic is the
most free-flowing of the Permlastic materials. It is excellent for
inlay and fixed bridge impressions. Light-Bodied Permlastic is a
syringe material that is usually used with Heavy-Bodied Permlastic.
Light Body bonds completely with both Regular and Heavy Bodies,
resulting in impressions with great accuracy and fine definition.
Heavy-Bodied Permlastic is formulated for use
whenever a stiffer material is indicated. The heavy body consistency
results in optimum compression of the Light-Bodied Permlastic in a
double-mix, copper-band impression. |
