3. Arrange artificial teeth
- 3.1 Follow prescription 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 prescription
- 6.1 Evaluate the prescription, the casts and the denture design and decide whether to use a duplicate cast 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
- 7.2 Identify the appropriate investment technique
- 7.3 Identify the appropriate processing cycle
- 7.4 Select polymeric material to construct the prosthesis
- 7.5 Prepare system components in accordance with manufacturer's instructions
- 7.6 Allow materials to reach application stage
8. Process denture or appliance
- 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 or appliance
- 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 prescription
- 9.4 Make any necessary adjustments to maintain original vertical dimension
- 9.5 Remove any processing irregularities and sharp edges
- 9.6 Polish the non-fitting surfaces of the prosthesis to create smooth, polished surfaces
- 9.7 Evaluatethe finished prosthesis
- 9.8 Decontaminate the dentures according to infection control guidelines
- 9.9 Place in a sealed container for dispatch
RANGE STATEMENT
The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Artificial teethmay include:
Acrylic
Porcelain
Positioning and attaching the prescribed artificial teeth may include:
Working in a manner that produces:
occlusion and articulation that is appropriate to the client's recorded jaw relationship
the desired aesthetic appearance
a prosthesis that maximises stability, support and retention
maximum masticatory efficiency
Factors to be considered when selecting polymeric materialmay include:
The preference of the clinical operator
The other materials in the prosthesis
The aesthetic requirements of the finished prosthesis
Confirmation of articulation may include:
Restoring centric occlusion
Restoring balanced occlusion
Restoring function
Evaluation ofthe finished prosthesis may include:
The quality of the finished prosthesis and freedom from defects including:
porosities
impurities through the acrylic
inadequate adaptation of acrylic to teeth
movement of teeth
The functional effectiveness of the design
Fit to the model
Compliance with the original prescription

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.
Critical aspects for assessment and evidence required to demonstrate this competency unit:
The individual being assessed must provide evidence of specified essential knowledge as well as skills
Assessment should replicate workplace conditions as far as possible
Consistency of performance should be demonstrated over the required range of workplace situations
Context of and specific resources for assessment:
Simulations may be used to represent workplace conditions as closely as possible
Where, for reasons of safety, access to equipment and resources and space, assessment takes place away from the workplace, simulations should be used to represent workplace conditions as closely as possible
Method of assessment
Evidence of essential knowledge and understanding may be provided by:
traditional or online (computer-based) assessment
written assignments/projects
Case study and scenario as a basis for discussion of issues and strategies to contribute to best practice
Questioning
Staff and/or client feedback
Supporting statement of supervisor
Authenticated evidence of relevant work experience and/or formal/informal learning
Role play/simulation
Access and equity considerations:
All workers in the health industry should be aware of access and equity issues in relation to their own area of work
All workers should develop their ability to work in a culturally diverse environment
In recognition of particular health issues facing Aboriginal and Torres Strait Islander communities, workers should be aware of cultural, historical and current issues impacting on health of Aboriginal and Torres Strait Islander people
Assessors and trainers must take into account relevant access and equity issues, in particular relating to factors impacting on health of Aboriginal and/or Torres Strait Islander clients and communities
