Warning and Precautions

SprintRay NightGuard Firm is non-toxic in processed, cured form, and is classified as a biocompatible material. In uncured form, NightGuard Firm is classified as a sensitizer. When washing with solvent or grinding the device, do so in a well-ventilated area with proper protective equipment.

Skin Contact: May cause skin irritation. If unprocessed resin contacts the skin, wash thoroughly with soap and water. May cause an allergic skin reaction. If skin sensitization occurs, stop using. If dermatitis or other symptoms persist, seek medical assistance.
Inhalation: High vapor concentration may cause headache and irritation of the eyes and/or respiratory system. If exposed to a high concentration of vapor or mist, move to fresh air. Use oxygen or artificial respiration as required.
Eye Contact: Wash the contacted area thoroughly with soap and water.
Ingestion: Contact your regional poison control centre immediately.

Storage

Material Reuse: The remaining resin in the resin tank can be reused. You may use a filter to ensure the resin is free from any cured particles to avoid print failures. The remaining material in the tank can be poured back into the resin bottle upon filtration. This process can be repeated until the material in the bottle is fully consumed. Please note that in the case of reuse, the resin must be filtered and poured back into the same bottle.

Store NightGuard Firm at 15-25oC (60-77oF) and avoid direct sunlight.
Keep the bottle closed and/or the tank lid securely attached when not in use.
Before disposal, completely polymerize.
Do not use NightGuard Firm after the expiration date printed on the bottle.
Do not use expired resin; biocompatibility and print stability may be compromised if expired photoinitiators do not activate properly.

Fabrication of Device

Designing

The device is designed in STL file format by a dental design service or dental CAD software using digital anatomical data from the patient.
This STL file is delivered to the clinician for fabrication.

3D Printing

Sign in to RayWare Cloud and select the appliance type; the algorithm will automatically orient and add supports. Select SprintRay NightGuard Firm material and use 100-micron layer thickness. Queue the job to your printer.
Shake the resin bottle thoroughly for one minute, then pour into the resin tank up to at least the min fill line. From the printer touchscreen, navigate to the printer queue. Start the print job.

Part and Support Removal

After your device has been printed, remove it from the print platform using the provided Print
Removal Tool. Remove all supports using a flush cutter or round diamond disc. Cut as close as possible to the device to minimize the smoothening and finishing procedure.

Washing and Drying

Use ≥91% IPA to wash the device using the SprintRay Pro Wash S or SprintRay Pro Wash/Dry:
Standard cleaning cycle
Dry the part completely before post-curing.

Post Curing

Use one of the following post-curing equipment from SprintRay to cure the device and select the preprogrammed profile for NightGuard Firm:
ProCure 2 (preprogrammed material profile)
ProCure (preprogrammed material profile)

Finishing

Use A Scotch-Brite/Fuzzies Wheel with a lab handpiece to smoothen the surface.
Polishing and Disinfect
Use pumice and a muslin wheel to remove minor scratches from the surface of the appliance, then use a polishing compound and muslin wheel to polish. Wash and clean the device with a brush using soap and warm water.
