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
HLTDT301C Construct models
HLTDT302C Construct custom impression trays
HLTDT304C Articulate models and transfer records
HLTIN301C Comply with infection control policies and procedures
Course Description
This unit of competency describes the skills and knowledge you will require to construct a single crown, or a combination of two or more crowns known as a bridge. - used to replace a natural tooth. The crown and bridges that you construct are designed to restore function in harmony with the patients natural dentition. All procedures must be carried out in accordance with occupational health and safety policies and procedures, current infection control guidelines, Australian and New Zealand Standards, State/Territory legislative requirements and organisation policy.

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 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.
- Accutrac models
- Inlays in artificial teeth
- Full gold crown (1)
- Full gold crown (2)
