DRAFT FOR REVIEW |
Start: Case received in Medit Lab
End: Try-in bagged and logged in SEAZONA for outbound delivery
1. Purpose
This procedure standardizes in-house manufacturing of SprintRay Try-In 2 devices used to evaluate bite registration and occlusion for fully and partially edentulous patients before definitive denture fabrication.
2. Scope
In scope: Medit Lab intake → scan QC → design (VERIFY) → RayWare / Pro 2 → ProWash S → NanoCure → finish clean → bag & SEAZONA.
Out of scope: Definitive printed dentures (SOP-LAB-090); Apex Flex RPD (SOP-LAB-030); OnX Tough 2 (SOP-LAB-040); clinical bite evaluation appointment itself; non-SprintRay printers.

8. Procedure
A. Intake & scan QC
- Medit Lab: verify ID, arch, edentulous status, due date.
- QC-SCAN.
B. Design (VERIFY)
- Design/receive try-in STL meeting thickness minima.
- Lab Technician approves. QC-A.
C–D. Nest & print
- Try-In appliance; Try-In 2 material; intaglio away; ~100 µm; Pro 2.
- Shake 1 minute; print; log lot. QC-B.
E–F. Wash & cure
- ProWash S standard cycle; dry. QC-C.
- NanoCure Try-In 2 profile; remove supports. QC-D.
G. Finish, clean, bag
- Soap + brush + warm water; dry; bag; SEAZONA. QC-E.
End of SOP-LAB-120. Clinical bite evaluation is Doctor-led outside this SOP.
