Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

HLTIN301C Comply with infection control policies and procedures
HLTWHS300A Contribute to WHS processes

Course Description

This unit of competency describes the skills and knowledge you will require to construct a trial prothesis suitable for insertion in the mouth; convert it to clinically acceptable materials and finish. The prosthesis you construct will cover a range of different types of "average" patient jaw relationships as well as "abnormal jaw relationships". The prosthesis (denture) constructed will need to be constructed in a way that it is suitable for insertion into a patients mouth.

Learning Outcomes

On completion of this course you will be able to demonstrate, on a consistent basis, the arrangement of artificial teeth for complete prosthesis (dentures) as well as techniques for converting the wax trial dentures into a final hard acrylic suitable for wear by a patient. You will set teeth in various arrangements in accordance with a prescription and be exposed to different techniques of curing the dentures.

Details of Learning Activities

Participation in group activities based on a simulated workplace exercises.
Practical exercises
Individual exercises carrying out requirements of competency.

Overview of Assessment

You will be assessed in a simulated workplace and under the normal range of work conditions.

You will be assessed on both the essential knowledge and the demonstration of essential skills through;

Completion of practical exercises - including detailed self reflection of each exercise
Practical exam
Theory exam


Assessment Tasks

Practical exercises:

  1. Maxillary Denture
  2. Class I Denture
  3. Class II Denture
  4. Class III Denture

Assessment guidelines for the practical exercises, as outlined in the practical exercise book.

Practical competency examination

  1. Class I Full/Full denture set-up for try-in
  2. Class I Full/Full denture process and finish

Theoretical examination

Construct simple complete removable acrylic dentures and appliances

One element of the 3 hour exam (divided into competencies) PASS MARK 60%, If ’NYC’ (Not Yet Competent) result is achieved the student will be provided with detailed feedback of the shortcomings and given a further opportunity to sit a secondary exam.

If a grade of 40% or less is achieved the student will NOT be granted an opportunity to sit a secondary exam and the student will be required to re-enroll in the unit which will be incurr fees.

Please note: A subsequent NYC result for any of above mentioned assessments may require the student to attend further class work within their enrolment period or may result in the student re-enrolling in the unit which will be incurring fees.
