• 2.2Construct sprue former as necessary
• 2.3Prepare the refractory model appropriately and apply an appropriate hardener or sealant
• 2.4Wax and invest removable partial denture framework

3 Wax and invest removable partial denture framework

• 3.1Transfer design outline correctly to the refractory model
• 3.2Select appropriate wax and pre-formed components
• 3.3Wax up patterns to the refractory cast consistent with the design
• 3.4Sprue the pattern using material of the correct size and in the correct shape and position for the material being cast, and attach it to the investment former
• 3.5Select appropriate investment and technique according to the alloy
• 3.6Prepare investment materials in accordance with manufacturers’ instructions
• 3.7Treat the surface of the wax, patterns and sprues
• 3.8Allow for investment setting time in accordance with manufacturer’s instructions

4 Burnout and cast removable partial denture framework

• 4.1Select appropriate alloy according to work order
• 4.2Select burnout and preheat cycles for appropriate investment and alloy combination
• 4.3Burnout wax from investment mould and hold at recommended temperature for casting
• 4.4Melt alloy and cast using appropriate materials, equipment and techniques

5 Devest, trim, finish and evaluate alloy structures for removable partial denture

• 5.1Select and apply cooling cycle
• 5.2Remove the cast alloy structure from the investment without damaging the integrity of the structure
• 5.3Remove oxides using an appropriate abrasive or chemical treatment
• 5.4Visually examine the cast alloy structure and correctly identify any casting faults and assess the viability of the casting
• 5.5Remove sprues and trim and shape the alloy structure
• 5.6Treat the surface of the alloy using appropriate materials and equipment, and finish using appropriate abrasives and polishes
• 5.7Position the cast on the master model and check accuracy of major connection and clasps, and adjust any metal occlusal contacts with antagonist
• 5.8Decontaminate the denture framework according to infection control guidelines
• 5.9Dry the denture framework, replace on model and place in a sealed container for dispatch

What does an assessment tool for HLTDET008 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for HLTDET008 needs to address all 44 unit components: 5 elements with 33 performance criteria, 3 performance evidence requirements, 8 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for HLTDET008?

Auditori pulls the current release of HLTDET008 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for HLTDET008 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing HLTDET008 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of HLTDET008, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
