This article demonstrates how a dental assistant can assist a dentist during triple tray crown and bridge procedures. This Is the first part of a two-part article, and explains mixing impression materials, making pre-operative dual-arch Impressions, deciding in what situations to use separate arch Impressions Instead of the triple tray, and Introduces the topic of making provisional restorations.
