Методика дублирования протезов. См. Step 4.

Step 1. Clinic
• Correct under-extension with greenstick tracing compound.
• Record impressions with silicone putty of polished surface and teeth,
using large disposable tray. Complete mould with second mix of putty
to record fit surface (use a separating medium—white soft paraffin or,
better, emulsion hand cream).
• Open mould, clean dentures, and return to patient.
• Send putty moulds to laboratory.
Step 2. Laboratory
• Fabricate self-cure acrylic baseplates on the silicone model of the fit
surface.
• Pour wax into remaining space.
• After cooling remove completed copy, cut off sprues, and polish.
Step 3. Clinic
• Employ the copies (‘replica record blocks’) to record required changes
in denture shapes (% Treatment planning, p. 322), by adding or
removing wax. Record working impressions in low-viscosity silicone with
adhesive to aid retention on base.
• Record jaw relationship with ‘bite recording paste’.
• Select shade/moulds for new teeth.

Step 4. Laboratory
• Cast impressions and articulate.
• Set-up, cutting away modified replica rims to substitute new teeth
(rather like setting up an immediate denture).
• Wax-up, including borders defined by working impressions.
Step 5. Clinic
• Try-in stage.
Step 6. Laboratory
• Finishing stages as normal.
Step 7. Clinic
• Normal insertion stage (and subsequent review)
