DRAFT FOR REVIEW |
Start: Case received in Medit Lab with scan QC
End: Guide bagged and logged in SEAZONA for outbound delivery
1. Purpose
This procedure standardizes in-house manufacturing of SprintRay surgical guides — Surgical Guide 3 as the primary resin path, with a documented Precision Guide fork for Pro 2-only cases — so every guide 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 print → ProWash S → NanoCure → finish → lab clean → bag & SEAZONA. Sleeve insertion and autoclave sterilization may be completed in-lab per IFU when practice policy requires (VERIFY who autoclaves — lab vs clinical).
Out of scope: Chairside scanning / CBCT planning technique; surgical placement; patient delivery; non-SprintRay printers.

5. Safety
- Treat uncured Surgical Guide 3 / Precision Guide as sensitizers/hazardous. Ventilate; PPE (nitrile, eyewear, gown, face protection).
- Do not place incompletely cured resin in the mouth. Do not bag under-cured guides.
- Do not substitute non-validated printers/washers/cure units.
- Cure waste resin fully before disposal. Do not use expired resin.
- Yellowish color after cure (Surgical Guide 3) may clear during sterilization — do not scrap solely for post-cure yellowing.

8. Procedure
A. Intake & scan QC
- Open case in Medit Lab.
- Verify ID, arch, implant sites, resin (Surgical Guide 3 vs Precision Guide), sleeve system, due date.
- Scan QC: required scans/models usable; no critical holes or wrong-patient files.
- QC-SCAN: Pass → continue. Fail → return to office.
B. Design (VERIFY path)
- Import into practice design path (VERIFY: outside CAD or SprintRay Cloud Design).
- Design/receive surgical guide STL per approved plan.
- Export STL; Lab Technician approves.
QC-A: Holes/sleeve positions match plan; seating OK; correct resin noted; STL labeled. Fail → redesign.
C. Nest (RayWare / Print Setup)
- Import approved STL.
- Select appliance type Surgical Guide; printer Pro 2.
- Select Surgical Guide 3 or Precision Guide per Rx.
- Orientation: intaglio facing away; layer thickness typically 100 µm; default / auto supports (Precision Guide: Dashboard Print Setup auto-orient).
- Queue to Pro 2 only.
D. Print
- Shake resin 1 minute; pour to min fill; record lot; assign material; clean platform; start print.
- QC-B: Fully formed; sleeve holes open/usable; no delamination. Fail → remake.
E. Wash & dry
- Surgical Guide 3: ProWash S standard preprogrammed cycle, IPA ≥ 91%.
Precision Guide: ProWash S Standard Multi-Cycle 3/3/3.
- Fully dry.
QC-C: Clean + dry.
F. Post-cure
- NanoCure: select Surgical Guide 3 or Precision Guide exact profile. Do not invent times.
- Remove supports (flush cutter / diamond disc); smooth with Scotch-Brite / Fuzzies. Optional pumice/compound polish.
QC-D: Fully cured; geometry intact.
G. Finish, sleeves, sterilize (VERIFY ownership), bag
- Lab clean with soap + brush + warm water; dry.
- Insert surgical guide sleeves into drill holes when assigned to lab.
- If lab autoclaves: 5 min at 134 °C (Surgical Guide 3); Precision Guide: 5 min at 134 °C then dry 15 min at 134 °C. Note expected color change after autoclave.
- If clinical autoclaves: bag as clean finished guide with sleeves status noted in SEAZONA; do not claim sterile unless autoclaved.
- Label, bag, SEAZONA bagged / outbound.
QC-E: Finish OK; cleaned; bagged; logged; sterilization status documented.
End of SOP-LAB-070. Surgery and clinical delivery are outside this procedure.
