Prepare environments, custom-made trays, casts and dies for the design and manufacture of restorations LEGACY

"This standard focuses on preparations for the design and manufacture of restorations -single metallic restorations, single metallic restorations and copings for the application of tooth coloured materials, single tooth coloured restorations, metallic substructures and metallic bridge components, single tooth coloured restorations based on metallic substructures and tooth coloured bridge restorations based on non-metallic substructures. You need to prepare and maintain environments, materials and equipment for the design and manufacture of the restoration, produce custom made trays, working casts and dies. 
In this standard, the term 'client' is used to mean the member of the oral health care team who has prescribed the custom-made 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 restoration is being made.
Users of this standard will need to ensure that practice reflects up to date information and policies."

"1.     access and accurately interpret all relevant work instructions and information
2.     work safely at all times and in accordance with all relevant legislation, guidelines, policies, procedures and protocols
3.     deal promptly and effectively with any problems within your control and report those which cannot be solved
4.     identify and minimise hazards and risk in the workplace
5.     communicate with relevant others at a pace, manner and level appropriate to their understanding, preferences and needs
6.     review the prescription and contract and correctly identify the materials and equipment which will be required
7.     confirm that the environment in which the work is to be undertaken is in a fit state ready for use and if it is not, take any necessary remedial action
8.     select the correct type and quantity of materials that will be required
9.     confirm that the required equipment is clean, in working order and set correctly
10.  move and handle equipment and materials in an appropriate, safe manner which is consistent with current legal and organisational requirements
11.  evaluate the casts or the digital representation and the prescription to determine what needs to be incorporated into the design of custom-made trays for:

• the individual's dentition
• the intended impression material or technique for use of the appliance
  12.  apply appropriate spacer materials to the cast or create digital representations to:
• eliminate undercuts
• provide the correct amount of space for the impression material selected by the client
  13.  apply a separating medium to the cast that is appropriate to the cast material and the processing method to be used
  14.  select materials that are appropriate to the nature and construction requirements of the custom-made tray and prepare them in the correct manner and quantity
  15.  form the selected material over the cast to the predetermined peripheral outline, and where required, fix appropriate handles and finger rests
  16.  process materials using the correct method for the material concerned
  17.  separate the appliance from the cast in a manner that prevents damage and remove any spacing materials that remain
  18.  smooth the periphery, handle and other surfaces of the appliance and perforate the tray surface as required
  19.  confirm that the finished tray is clean, is free of defects and conforms to the prescription
  20.  effectively clean the custom-made device, correctly identify it with the individual's unique reference and date of production and return it to the client at the correct time
  21.  make complete, accurate and up-to-date records relating to the identification, components and manufacture of the manufactured device
  22.  on receipt of the custom tray impression or appropriate digital information, correctly determine the prescription requirements from the information available
  23.  effectively clean the received impression, confirm that it is free of voids or defects which render it unacceptable and prepare it appropriately to receive the cast material
  24.  inform the client in an appropriate manner if the impression is not of sufficient quality and obtain a replacement impression
  25.  prepare cast and die material which is appropriate for:
• the process which will be used to manufacture the final restoration
• the nature of the impression material
  26.  pour the cast and die material into the impression to produce casts and dies that:
• provide an accurate positive image of the impression
• include the detail and area that is required to make the restoration
• are dense
• are free from voids or other visible defects
  27.  construct soft gingival areas appropriately to the required amount for the dies that need them
  28.  produce margin edges on dies by sectioning and trimming them accurately to the clinical edges reproduced on the impression
  29.  finish casts and dies so that they meet auditing and recording requirements
  30.  evaluate casts and dies against restoration requirements and eliminate any unnecessary undercuts
  31.  correctly identify casts and dies with the individual's unique reference
  32.  mount casts on an appropriate articulator, articulate them correctly and consistently with the individual's occlusal registration and record the necessary information correctly
  33.  apply die surface hardener and spacing materials if these are required
  34.  store casts and dies which are not in use in an appropriate safe manner and place
  35.  dispose of waste in accordance with organisational procedures
  36.  complete and store all relevant documentation in accordance with organisational requirements"
