HLTIN301C Comply with infection control policies and procedures
HLTWHS200A Participate in WHS processes

Course Description

This unit of competency describes the skills and knowledge required for you to design and manufacture registration rims for removable prostheses. The registration rims that you manufacture are used for full dentures and also partial dentures. You will construct a range of stabilised base plates as well as the use of wax and wire. 
All procedures are carried out in accordance with work health and safety (WHS) policies and procedures, current infection control guidelines, Australian and New Zealand Standards, state/territory legislative requirements and organisation policy.

  1. Completion of practical exercises - including detailed self reflection of each exercise
  2. Practical exam - Construction of F/F Registration Rims on stabilised baseplates within the time limit of 3.5 hours
  3. Theory exam - Pass mark 60%


Assessment Tasks

Practical exercises and practical exams - PX/CA or NYC

  1. Pink Self-cure acrylic Mx baseplate
  2. Clear Self-cure acrylic Md baseplate
  3. F/F Registration rims
