Instructions For Use

Indications for Use

The SprintRay Try-In 2 resin is a light-curable polymerizable resin intended to evaluate bite registration and occlusion for fully and partially edentulous patients. This material is an alternative to traditional Try-in denture material.

Device Description

Fabrication of dental appliances with this device requires computer-aided design and CAD/CAM manufacturing system that includes the following components not part of the device:  digital file created in an optical impression system, 3D printer, and curing light equipment. The material is intended exclusively for professional dental work.

Notification:

The device specifications have been validated using the software, printers, and process parameters specified in this document. Any other printers, operation software and post-printing processes will be outside of the device specifications and the FDA clearance. Users shall follow this document to use the device.

Contra-indication

The SprintRay Try-In 2 resin is contraindicated in case of the following:

  • If a patient is known to be allergic to any of the ingredients.
  • Direct intraoral contact of uncured or partially uncured material.
  • For every application that is not part of the indication (see above)

Warning

  • The SprintRay Try-In 2 resin is non-toxic in solid form, and it is classified as a biocompatible material. It is also classified as a sensitizer, which means that exposure over time can cause your body to have a mild allergic reaction. May cause skin irritation. May cause an allergic skin reaction. If contact with skin, wash thoroughly with soap and water. If skin sensitization occurs, discontinue use. If dermatitis or other symptoms persist, seek medical assistance.
  • Avoid inhalation or ingestion. High vapor concentration can cause headache, irritation of eyes or respiratory system. Direct contact with eyes may cause possible corneal damage. Long-term excessive exposure to the material may cause more serious health effects. Monitor air quality per OSHA standards.
  • Eye Contact: Immediately flush eyes with plenty of clean water for at least 20 minutes and consult a physician. Wash the contacted area thoroughly with soap and water.
  • Inhalation: In case of exposure to a high concentration of vapor or mist, remove person to fresh air. Give oxygen or artificial respiration as required
  • Ingestion: Contact your regional poison control center immediately.

Precautions

  • When washing the printed Try-In 2 with solvent or grinding the Try-in denture, it should be in a properly ventilated environment with proper protective masks and gloves.
  • 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.
  • Recommended storage conditions for unprocessed SprintRay Try-In 2 are at 15 – 25 C (60 -77 F) and avoid direct sunlight.
  • Keep the container closed when it is not in use.
  • Expired or unused SprintRay Study Try-In 2 should be completely cured or polymerized prior to disposal.
  • Product shall not be used after expiration date.
  • For activation and complete polymerization of the SprintRay Try-In 2 please follow the steps involved in “Fabrication of Try-in Denture” and “Post-curing”.

Fabrication of Try-in Denture

1. Design of the Try-in Denture

  • Once the intraoral scans of the patient are submitted to a dental-design service/lab, the dental model is designed and provided in STL file format by the dental-design service/lab.
  • Ensure the minimum thickness of the Try-in base meets the following:
Area Maxillary Mandibular

Lingual Ridge area

≥ 2.0 mm

≥ 2.0 mm

Palatal/Lingual

≥ 2.5 mm

≥ 1.5 mm

Facial/Buccal

≥ 1.5 mm

≥ 1.5 mm

Implant Over Denture area

≥ 2.0 mm

≥ 2.0 mm

2. Printing

  • Bring the designed STL files to RayWare. Position the Intaglio surface of the Try-in Denture toward the print platform (teeth facing up), with the posterior portion of the design angled toward the platform at 60°. (Fig. 1)
  • Add supports. Remove all supports from the palatal intaglio surface but leave them on the flange perimeter. (Fig. 2)
  • Select “SprintRay Try-In 2” resin setting for print-setting and use 100-micron thickness.
  • Ensure Resin Tank is fully secured and filled to the recommended resin level.
  • Ensure the Print Platform is clean, dry, securely placed, and locked on the platform-arm

3. Washing and Drying

  • After your Try-in Denture has been printed successfully, it must be washed using Isopropyl Alcohol (IPA) with a concentration of 91% or higher before being post-cured.
  • SprintRay highly recommends Pro Wash/Dry for your cleaning process; however, if you don’t have access to a Pro Wash/Dry yet, you may allocate a separate Ultrasonic bath dedicated to post-print washing with IPA, or alternatively, a dish for soaking along with a Soft/Medium bristle brush to manually clean your prints in IPA.
  • Ensure NOT to immerse the Try-in Denture for more than 10 min in the IPA bath.
  • Remember: IPA is highly flammable! Please keep it away from heat sources, sparks, and flames.
  • Ensure that your Try-in Denture is completely dry before the next step; if not, use compressed air to dry your Try-in Denture rapidly.
  • Remove the Try-in Denture from the Print Platform.

4. Support Removal

Once removed from the Print Platform, we need to remove all the supports by using a flush cutter. Try to cut as close as possible to the Try-in Denture to minimize the smoothening and finishing procedure.

 

5. Post Curing

  • Next, the printed Try-in Denture needs to be properly post-cured using a ProCure to maximize strength and accuracy and comply with required standards.
  • All the post-curing settings are preset in ProCure 1 and ProCure 2 units
  • Wash and clean the device with a brush using soap and warm water.
