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.

Teaching Schedule
The class is scheduled for delivery to the NON APPRENTICE group (FT1) on Monday July 18 in the Lecture theatre of Building 154 RMIT (within the Royal Dental Hospital Melbourne) Notification will be provided via student email if the date or location change. Following the delivery of the theory class, practical exercises will be undertaken in the laboratory. Class schedules are detailed in the timetables provided on Blackboard (subject to change at the discrection of RMIT, in this event notification will be provided to your student email); Practical classes will be delivered in the simulated environment at RMIT where the Teacher will provide demonstration and assistance as you construct the following appliances. Complete Mx DentureF/F Class IF/F Class IIF/F Class III The TIER 2 exercises are made available if you complete all of the previous exercises and are seeking further practice prior to the assessments. The time guides for the TIER 2 exercises are reduced and require a ’self-managed approach’ to complete the exercise.

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
You will attempt the following practical exercises under supervision of the teacher and you will be graded with either a CA (Competency Achieved) or NYC (Not Yet Competent) according to the assessment guidelines outlined in the practical exercise book; in accordance with the training package elements & essential skills. Complete Mx DentureF/F Class IF/F Class IIF/F Class III The TIER 2 exercises are made available if you complete all of the previous exercises and are seeking further practice prior to the assessments. The time guides for the TIER 2 exercises are reduced and require a ’self-managed approach’ to complete the exercise. If you attempt the following practical exercises you will be graded with either a Px (Satisfactory) or NYC (Not Satisfactory) according to the assessment guidelines outlined in the practical exercise book; in accordance with the training package elements & essential skills.
