Course Objectives

1.5 CE Credits

This course demonstrates a predictable step-by-step technique for crown preparation that is essentially sequenced backwards from what nearly all dentists were taught in dental school. With a focus on precise margination and adequate reduction in critical areas through the use of depth cuts, the Reverse Preparation technique gives dentists a way to prepare teeth that will have their laboratory technician complimenting their preparations.

Learning Objectives

  • Understand the need for optimal tooth reduction to maximize the strength and esthetics of restorative materials.
  • List the types of margins and the indications for each.
  • List the burs needed to perform the Reverse preparation technique.
  • Explain the benefits of depth cuts to ensure proper tooth reduction of preparations.
  • Explain the benefits of electric handpicks.
  • Learn a preparation technique for when depth cuts cannot be used, such as replacing an existing crown.
