Course Description:

Though all levels of assistants are welcome to attend, this interactive workshop is designed mainly with newer dental assistants in mind. Does your anxiety build when you are asked to assemble the matrix retainer? We will review matrix systems to gain competence and confidence with this critical step for consistent interproximal restorations. Assembly and placement of retainers, retainer-less and sectional systems will be practiced, followed by wedge selection/placement. Strictly as an exercise to evaluate technique of matrix application, composite will be placed and cured, band will be removed, and margins examined.

Learning Objectives:

  • Compare traditional and sectional matrix systems.
  • Assemble, place, and evaluate matrix and wedge systems for various preparations.
  • Evaluate matrix technique by examining gingival margin after placing restoration on a model.
