Design and manufacture tooth coloured bridge restorations based on non-metallic sub-structures
Overview
"This standard describes the design and manufacture, using manual or digital techniques, of tooth coloured restorations by designing and manufacturing non-metallic bridge sub-structures. You need to design and manufacture non-metallic bridge sub-structures, apply tooth coloured materials to non-metallic bridge sub-structures, and finish them ready for fitting in the individual's mouth.
The term 'client' is used to mean the member of the oral health care team who has prescribed the restoration. 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 restoration is being made.
Users of this standard will need to ensure that practice reflects up to date information and policies."
Performance criteria
You must be able to:
"1. access and accurately interpret all relevant work instructions and information

4. communicate with relevant others at a pace, manner and level appropriate to their understanding, preferences and needs
5. identify and minimise hazards and risk in the workplace
6. collate all specification information required for the design and manufacture of the tooth coloured restorations based on non-metallic sub-structures
7. confirm accuracy of the specification with relevant others
8. select the necessary components, materials and equipment and confirm that they are fit for purpose
9. set up the manufacturing equipment in accordance with the specification
10. manufacture the tooth coloured restorations based on non-metallic sub-structures using appropriate methods and techniques
11. monitor the manufacturing process and adjust as required
12. devest or retrieve the manufactured product using an appropriate method which releases the item without causing damage
13. check that the manufactured product matches the specification and make any necessary adjustments
14. dispatch in accordance with organisational requirements
15. dispose of waste in accordance with organisational procedures
16. complete and store all relevant documentation in accordance with organisational requirements"

4. specific procedures for reporting issues which are beyond your competence, responsibilities and accountability
5. the duty to report any acts or omissions that could be unsafe/detrimental to you or others
6. how to communicate with relevant others at a pace, manner and level appropriate to their understanding, preferences and needs
7. the hazards and risks which may arise during the execution of your work role and how you can minimise these
8. the correct use of any equipment and PPE to protect the health and safety of you and others
9. the principles and use of digital design and manufacturing
10. relevant digital manufacturing equipment, methods and techniques
11. the skeletal anatomy, physiology of the head and neck and tooth morphology
12. the structure, function, and movement of the oro-facial musculature including the tongue and temporomandibular joint
13. disorders and diseases affecting the oral cavity
14. the aetiology and classifications of malocclusions
15. the physiological and pathological changes associated with the ageing process and trauma related to the oral environment
16. the importance of retention of the periodontal ligament and the changes in proprioception due to loss of periodontal ligament
17. the broader factors (sociological, behavioural, environmental and economic) that contribute to oral health and illness
18. the principles and practice of:
* articulation
* aesthetics and phonetics
19. the principles of restoration design
20. the effect of masticatory forces on dental restorations, the properties required of a material and restoration design and manufacture to resist masticatory loads and support hard tooth structures.
21. the classification and sub-classification of materials on the basis of chemical composition and internal structure
22. non-metallic materials used in restorations
23. purpose of abutments retainers and pontics
24. how to place the non-metallic sub-structure on the cast and confirm that:
* it fits the cast
* it complies with the prescription
* it will not damage surrounding tissues in the individual's mouth
25. manufacturing considerations to include:
* the individual's natural tooth form
* tooth morphology
* effects of adjacent natural teeth and of restorations
* pontic coronal form
* profile of pontic in relation to aesthetics and to avoid trauma to the residual ridge
* aesthetic requirements
* prescription requirements
26. the mechanical, physical, thermal, chemical and biological properties of materials waxes used in the manufacture of restorations
27. aesthetic restorative materials
28. the relationship between chemical bonds and the properties of solid materials
29. duplicating and cleaning materials
30. methods of developing, maintaining and improving communication and information relating to the provision of custom-made dental devices
31. methods of infection control when handling received impressions and other items which may have been in the mouth, or which are intended to be placed in the mouth
32. principles of quality assurance including effective recording and sampling; processes and procedures for quality assurance in your workplace
33. methods of setting and calibrating equipment and of testing that this is correct
34. the effects of modifying manufacturers' products to meet laboratory requirements on the physical properties of products and on quality assured products, and the legal implications of poor manufacturing
35. the range of equipment used in the design and manufacture of dental devices
36. methods of using equipment and materials safely including the use of chemicals and other hazardous substances
37. methods of storing different equipment and materials safely and securely
38. methods of cleaning and maintaining different types of equipment
39. how to dispose of waste in accordance with organisational procedures
40. how to complete and safely store all relevant documentation in accordance with organisational requirements"
