DRAFT FOR REVIEW |
Start: Case received in Medit Lab
End: Denture bagged and logged in SEAZONA for outbound delivery
1. Purpose
This procedure standardizes in-house manufacturing of SprintRay rigid printed removable dentures (base + teeth) using Apex Base or High Impact Denture Base with matching teeth resins, so every case meets the same quality, safety, and traceability standard before leaving the lab.
2. Scope
In scope: Medit Lab intake → scan QC → design (VERIFY path) → RayWare / Pro 2 (± Duo Kit) → ProWash S → assemble & NanoCure → finish & polish → lab clean → bag & SEAZONA.
Out of scope:
- Apex Flex RPD flexible partials → SOP-LAB-030 (different resin, NanoCure Apex Flex Denture, clasp workflow)
- OnX Tough 2 fixed hybrids / monolithic tooth-shade prosthetics → SOP-LAB-040 (not a separate pink base + teeth assemble path)
- Chairside try-in delivery; Try-In 2 interim → SOP-LAB-120; clinical disinfection; non-SprintRay printers

5. Safety
- Treat uncured base and teeth resins as sensitizers. PPE + ventilation.
- Do not bag under-cured dentures. Do not substitute non-validated stack.
- Cure waste resin fully. Do not use expired resin.

8. Procedure
A. Intake & scan QC
- Open Medit Lab; verify ID, arch, base resin family, shades, due date. Confirm not Flex RPD or OnX hybrid unless misrouted.
- Scan QC; QC-SCAN.
B. Design (VERIFY)
- Design/receive separate base + teeth STLs meeting thickness minima.
- Lab Technician approves. QC-A: minima met; shades correct; STLs labeled.
C. Nest (RayWare + Duo preferred)
- Duo Mode on Pro 2 when available:
- Base: intaglio toward platform; ~60°; posterior closer; 100 µm.
- Teeth: occlusal toward/parallel platform; intaglio away; 100 µm.
- Fallback: sequential base then teeth jobs — document in SEAZONA.
D. Print
- Shake each resin 1 minute; pour; assign tanks; print; log lots.
QC-B: Complete geometry for base and teeth.
E. Wash & dry
- ProWash S with Duo adapter if used; IPA ≥ 91%; standard/multi-cycle per IFU.
- Dry fully — especially sockets.
QC-C: Clean + dry.
F. Assemble & post-cure
- Roughen sockets/tooth bases if needed.
- Place drop of base resin in each socket; seat teeth; press firmly; tack-cure until stable.
- Place assembled denture (dry) in NanoCure; select Conventional Denture; follow on-screen prompts. If mixing resin lines, MWG directs Conventional Denture path. Do not invent times.
QC-D: Bonded + fully cured.
G. Finish, clean, bag
- Remove supports; smooth; polish per kit; soap/steamer clean; dry.
- Bag + SEAZONA.
QC-E: Required for release.
End of SOP-LAB-090. Clinical try-in/delivery outside this SOP (see also SOP-LAB-120 for Try-In 2).
