Course Content (Themes, Concepts, Issues and Skills)

Use Computer Aided Design (CAD) system to design restorations
     Measurement (shapes of the die and adjacent teeth)
     Data Processing
     Data from a typical crown form to be applied to the imaged tooth preparation
     Determination of margin of die
     Primary adaptation of a standard crown on the die
     Adjustment of centric occlusion with the opposing tooth
     Occlusion surface modulation

Use Computer Assisted Machining (CAM) system to mill prostheses using CAD data.

Learn operational procedures for using CAM system to milling both tooth colored glass ceramic and zirconia.

Sintering or glass infiltration

Use of open and closed impression trays for implant cases

  • Position fixture replica on abutment
  • Pour models, cut and prepare dies for implant cases.
  • Select correct size, shape and manufacturer abutment for implant restoration.
  • Dental implant pontic design
  • Fabricate both screwed and cemented restorations to abutment restoration.
