  • 1.2 Read and interpret work order
  • 1.3 Articulate on an industry specific articulator in accordance with clinician requirements
2. Prepare case for setting of teeth
  • 2.1 Select artificial teeth in accordance with work order
  • 2.2 Modify bases and rims as required for positioning teeth
3. Arrange artificial teeth
  • 3.1 Follow work order to position and attach the prescribed artificial teeth
  • 3.2 Shape and contour the supportive wax and contour to gingival outline
4. Wax up denture for try-in
  • 4.1 Contour facial and lingual aspects
  • 4.2 Locate and relieve muscle attachments
  • 4.3 Smooth and round peripheral extensions
  • 4.4 Confirm distal extensions
  • 4.5 Decontaminate the trial prosthesis according to infection control guidelines
  • 4.6 Dry the trial prosthesis and place in a sealed container for dispatch
5. Check and modify the returned trial prosthesis
  • 5.1 Decontaminate the returned prosthesis and identify any modifications that are required
  • 5.2 Check the returned trial prosthesis for loosening or movement of teeth and make necessary adjustments
  • 5.3 Fit the returned trial prosthesis to the model if it needs to be modified, articulate and make necessary modifications
6. Wax case for finish consistent with work order
  • 6.1 Evaluate the work order, models and denture design and decide whether or not to use a duplicate model for processing the final prosthesis
  • 6.2 Apply wax as required by work order
  • 6.3 Contour facial and lingual aspects
7. Select and prepare materials and processing technique
  • 7.1 Identify the appropriate polymer system for case

8. Process denture
  • 8.1 Apply appropriate investment techniques
  • 8.2 Apply material to mould
  • 8.3 Process the polymeric material for the correct length of time at the correct temperature
  • 8.4 Devest model and remove the processed prosthesis without causing damage to it
  • 8.5 Trim excess material and remount on articulator
9. Finish denture
  • 9.1 Select methods, materials and equipment for trimming, finishing and polishing the prosthesis appropriate to the appliance and the materials used in its construction
  • 9.2 Reposition models on the articulator where possible
  • 9.3 Assess the articulated prosthesis and confirm that articulation is appropriate to the work order
  • 9.4 Make any necessary adjustments to maintain original vertical dimension
  • 9.5 Remove any processing irregularities and sharp edges
