Description
Employability Skills
Learning Outcomes and Application This unit of competency describes the skills and knowledge required to construct thermoformed bases and appliances such as mouthguards, bleaching trays and orthodontic retainers.This unit applies to work in dental technology.The skills in this unit must be applied in accordance with Commonwealth and State/Territory legislation, Australian/New Zealand Standards and industry codes of practice.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 orders

- 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

- 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.

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 work orders and constructed the following 3 appliances:

- mouthguard

- bleaching tray

- splint

• used standard precautions and safe work practices to trim, polish and finish 2 thermo-formed appliances suitable for insertion in the mouth

• critically evaluated the 2 different types of thermo-formed appliances produced to meet technical laboratory and clinician requirements.

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:

- articulation and occlusion

- 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

• polymer science

• relevant material science for carrying out procedures

• thermoforming technology.
