Design and manufacture cast and wrought metallic components and cast frameworks for removable prostheses

This standard focuses on the design and manufacture of wrought and cast frameworks, and metallic components for removable prostheses using manual or digital techniques. You need to manufacture wrought components; design and manufacture burn-out patterns for cast metal frameworks; and devest, trim, finish or use rapid manufacturing techniques and evaluate metallic structures.

The term 'client' is used to mean the member of the oral health care team who has prescribed the custom-made prosthesis. Clients may be external to the organisation (such as other laboratories, dental practitioners, training schools) or internal (within a dental hospital). The individual is the one for whom the custom-made prosthesis is being made.

The design and manufacturing process may be carried out in a regulated dental laboratory within a variety of settings.

Users of this standard will need to ensure that practice reflects up to date information, policies and regulations.

---

1. communicate with relevant others at a pace, manner and level appropriate to their understanding, preferences and needs
2. collate and confirm accuracy of all specification information required for the design and manufacture of the wrought and cast frameworks, and metallic components for removable prostheses with relevant others.
3. select the necessary components, materials and equipment and confirm that they are fit for purpose
4. set up and operate the manufacturing equipment in accordance with the specification
5. manufacture the wrought and cast frameworks, and metallic components for removable prostheses using appropriate methods and techniques adjusting manufacturing processes as necessary.
6. devest or retrieve the manufactured product using an appropriate method which releases the item without causing damage
7. ensure that the manufactured product matches the specification and make any necessary adjustments
8. dispose of waste in accordance with all relevant legislation, guidelines, and workplace procedures
9. complete and store all documentation in accordance with relevant legislation, guidelines, and workplace procedures
