Clinical Evaluations: Impression and Bite Registration Materials
Accurate impressions depend on proper technique as well as desirable material characteristics. Elastomeric impression materials (polyethers, polyvinyl siloxanes, and hybrids) are popular impression materials 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 clinical properties of elastomeric impression materials, compares polyethers and polyvinyl siloxanes, and answers some common questions about impression taking. In addition, bite registration techniques and materials are addressed.
