SOLD OUT: Tackling the Matrix: A Hands-On Workshop for Dental Assistants

Theresa Groody, DHSc, EFDA, CDA


Time: 1:30 pm - 4:30 pm Code: T27 Cost: SOLD OUT Date: Thursday, Oct. 27


CE Credits:  3 Hour Participation  |  Subject: Restorative/Dental Assisting |  Recommended for: Assistants | Notes: 24 Assistants attendees. Attendees bring safety glasses.

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 the technique of matrix application, the composite will be placed and cured, the band will be removed, and the margins examined.

Learning Objectives:

  • Recognize matrix systems used in offices and any challenges routinely faced.
  • Compare and contrast traditional and sectional matrix systems.
  • Assemble, place and evaluate matrix and wedge systems for various preparations.
