Description
Employability Skills
Learning Outcomes and Application This unit of competency describes the skills and knowledge required to take a tooth shade and construct ceramic and fixed restorations.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:

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 order for the following 4 fixed restorations

• fabricated the following 4 ceramic restorations using standard precautions and safe work practices to a standard that is suitable for insertion in the mouth:

- 1 maxillary or mandibular anterior crown

- 1 maxillary or mandibular posterior crown

- 1 anterior veneer

- 1 posterior inlay

• critically evaluated the work produced to meet technical laboratory and patient requirements including:

- shade of the ceramic matches the work order requirements

- fit of the restoration is accurate

- restoration is of an appropriate anatomical form, shape and surface finish

- restoration is free of faults

- restoration provides the correct occlusion and articulation

- proximal contact areas are in contact with the contact areas of the adjacent teeth.

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:
