Performance Evidence
The candidate must show evidence of the ability to complete tasks outlined in elements and performance criteria of this unit, manage tasks and manage contingencies in the context of the job role. There must be evidence that the candidate has:
• read and correctly interpreted 4 work orders
• used standard precautions and safe work practices to fabricate maxillary and mandibular registration rims using a range of flexible and rigid base and rim material for the following dentitions (4 rims in total):
- partial with a combination of bounded and unbounded saddle areas
- edentulous
• critically evaluated the 4 registration rims produced to meet technical laboratory and clinician requirements.
Knowledge Evidence
The candidate must be able to demonstrate essential knowledge required to effectively complete tasks outlined in elements and performance criteria of this unit, manage tasks and manage contingencies in the context of the work role. This includes knowledge of:
• Australian/New Zealand Standards, workplace health and safety (WHS) policies, Dental Board of Australia guidelines on infection control, Commonwealth and State/Territory legislation and organisation policies relating to dental laboratory work
• fundamental oral anatomy including:
- dentition – arrangement of the teeth, naming and coding of teeth
- structures of the oral cavity – hard and soft palate, lateral and posterior borders of the oral cavity, tongue and floor of the mouth
- teeth form and function
• properties of materials used to construct registration rims, including rigid and flexible bases.
Assessment Conditions
Skills must have been demonstrated in a dental laboratory workplace or in a simulated dental laboratory environment that reflects workplace laboratory conditions. The following conditions must be met for this unit:
• use of suitable facilities, equipment and resources including:
- access to work order
- Dental Board of Australia guidelines on infection control on which the candidate bases the planning process
- laboratory safety manuals and procedures in line with relevant Commonwealth and State/Territory legislation
- materials for construction of rims
- WHS policies on which the candidate bases the planning process.
Assessors must satisfy the Standards for Registered Training Organisations (RTOs) 2015/AQTF mandatory competency requirements for assessors.
