Elastomeric Impression Materials

Dental impression materials are used to record oral anatomy for the fabrication of fixed restorations, removable prosthodontics and appliances. The accuracy of these restorations depends on proper tooth preparation, the impression material, the technique used, and excellent communication with your dental laboratory. Elastomeric impression materials, addition silicone (PVS) and polyether, are popular because of their excellent physical and mechanical properties, including excellent detail reproduction, high elastic recovery and good dimensional stability. This issue of THE DENTAL ADVISOR reviews the properties and clinical characteristics of elastomeric impression materials. Clinical tips for the entire dental team are provided.
