Course Learning Outcomes
  1. Demonstrate the ability to mix pigment to arrive at a desired color through the manipulation of hue, chroma, and value.
  2. Demonstrate the ability to perform all laboratory steps involved in dealing with underprepared teeth, nonparallel abutments, and the placement of semi-precision attachments.

Performance Objectives:
  1. Describe and define terminology related to color theory.
  2. Demonstrate how to mix pigments to create a value scale, secondary hues, and manipulate chroma.
  3. Identify the basic principles of the physics of light as it related to pigments and dental porcelains.
  4. Perform the fabrication of post crowns and post and cores for endodontically treated teeth.
  5. Develop strategies to deal with under prepared teeth.
  6. Demonstrate how to fabricate reduction copings.
  7. Discuss intracoronal and extracoronal attachments.
  8. Describe the use of a semi-precision attachment on bridges with nonparallel abutments.
  9. Identify a stress breaker.
  10. Describe the use of attachments as abutments for removable partial dentures.
  11. Discuss swing lock retention for removable partial dentures.
  12. Demonstrate how to survey and place a semi-precision attachment
