Elements and Performance Criteria

Materials used may be:
Cast alloys
Acrylic resins (heat activated, chemically activated, thermoformed)
Visible light-cured composite resins

Splints to be fabricated include:
Cast metal alloy cap splints
Acrylic cap splints
Gunning splints
Wrought wire retained splints
Occlusal splints (bruxing, neutral, anterior, repositioning, TMJ, orthodontic)

Critical aspects of assessment:
The unit should be assessed over a range of dental laboratory materials, splint materials, jaw relations and malocclusions of a severe skeletal orthodontic type.
The unit should be assessed using a range of articulators
All work complies with relevant legislative requirements

Underpinning knowledge:
Articulation and occlusion
Relevant dental anatomy
Dental metallurgy
Relevant material science for carrying out procedures
Use of surveying equipment
OHS and material safety data sheets
Current NHMRC infection control guidelines
Processing of wax patterns in acrylic resin
Using vacuum forming procedures

Underpinning skills:
Manual dexterity
Surveying and blocking out undercuts
Selection of articulators
Use of face-bow and centric records
Planning of work

Interdependent assessment of units:
This unit may be assessed with other units making up a job role. The following units are pre-requisites for this unit:
HLTIN1A Comply with infection control policy and procedures
HLTDT1AConstruct models
HLTDT4A Articulate models and transfer records
HLTDT5A Arrange artificial teeth for complete dentures
HLTDT6A Wax, process and finish acrylic dentures and appliances

Resource implications:
This unit should be assessed by direct observation at work or through simulation. A simulated environment must contain all necessary equipment.
