Performance Evidence

The candidate must show evidence of the ability to complete tasks outlined in elements and performance criteria of this unit, manage tasks and manage contingencies in the context of the job role. There must be evidence that the candidate has:

• followed 1 set of sequenced written instructions and the manufacturers’ instructions for preparing materials used in immediate dentures

• used standard precautions and safe work practices to construct an immediate denture from at least one denture suitable for insertion in the mouth including 1 of each of the following:

- maxillary or mandibular anterior tooth with at least one of the following:

o flanged denture with bone re-contouring

o flanged denture without bone re-contouring

o open-faced denture

- maxillary or mandibular posterior tooth with at least one of the following:

o flanged denture with bone re-contouring

o flanged denture without bone re-contouring

o open-faced denture

• critically evaluated the 1 immediate denture produced to meet technical laboratory and patient requirements.

Knowledge Evidence

The candidate must be able to demonstrate essential knowledge required to effectively complete tasks outlined in elements and performance criteria of this unit, manage tasks and manage contingencies in the context of the work role. This includes knowledge of:

• Australian/New Zealand Standards, workplace health and safety (WHS) policies, Dental Board of Australia guidelines on infection control, Commonwealth and State/Territory legislation and organisation policies relating to dental laboratory work

• advantages of immediate dentures for the patient including:

- accurate positioning of the artificial teeth

- control of post-extraction haemorrhage

- correct restoration of the vertical and horizontal relationships between maxilla and mandible

- maintenance of appearance

• fundamental oral anatomy, including:

- dentition – arrangement of the teeth, naming and coding of teeth

- structures of the oral cavity – hard and soft palate, lateral and posterior borders of the oral cavity, tongue and floor of the mouth

- teeth form and function

• clinical treatment procedures necessary to prepare the patient for immediate denture insertion, including:

- where there are posterior teeth and no existing partial denture

- where a partial denture is present

• disadvantages of immediate dentures for the patient including:

- the implications for the patient where appearance of anterior artificial teeth cannot be approved at try-in

- the implications of rapid bone resorption following extraction

• types of immediate replacement dentures and their advantages and disadvantages:

- flanged denture without bone re-contouring

- flanged denture with bone re-contouring

- open-faced denture.
