Kerr Regular Permlastic
Permlastic is a rubber base impression material available in three viscosities:
1. Light body is excellent for inlay and fixed bridge impressions
2. Regular body is recommended for partial- or full-denture impressions
3. The denser viscosity of heavy body results in optimum compression of the light body in a double-mix or copper-band impression.
Polysulfide Impression Material
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.
