Description
Employability Skills
Learning Outcomes and Application This unit of competency describes the skills and knowledge required to construct and place an aesthetic, and functional implant retained overdenture.This unit applies to work in dental prosthetics where the dental prosthetist must enter into a structured professional relationship with a dentist as defined by the Dental Board of Australia before providing such treatment.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 the dental workplace or in a simulated environment that reflects workplace conditions. The following conditions must be met for this unit:

• use of suitable facilities, equipment and resources including:

- dental clinic/laboratory

- de-identified dental and medical records and charts for scenarios

- personal protective equipment

- Dental Board of Australia guidelines on infection control on which the candidate bases the planning process

• modelling of industry operating conditions including access to real people for simulations and scenarios of prosthetic procedures.

Assessors must satisfy the Standards for Registered Training Organisations (RTOs) 2015/AQTF mandatory competency requirements for assessors.
