Instructions For Use

Indication


The SprintRay Try-In 2 resin is a light-curable polymerizable biocompatible resin intended to be
used to fabricate teeth models, which can be used for fabricating Try-in Dentures for cosmetic
and not masticatory purposes.

 

Contraindication

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).

 

Handling and Processing

SprintRay Try-In 2 resin is non-toxic in both liquid and solid form, and it is classified as 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. May cause severe eye irritation. May cause respiratory irritation. Here is how to handle resin safely:

 

  1. Always wear gloves
    • Always wear gloves when handling uncured resin. Whether you are pouring, removing
      printed parts from the platform, or even after they have been washed, must wear gloves
      to limit exposure to resin.
  2. Mix thoroughly
    • 3D printing resins contain chemicals of different weights; therefore, it is essential to mix
      resin before every print thoroughly. For resin already in the tank, use provided resin wiper
      to stir the material gently. If pouring from a bottle, shake the bottle vigorously for several
      minutes before dispensing
  3. Check expiration dates
    • Resin has a shelf life; it is essential to keep an eye on the expiration date. The use of
      expired resin will likely result in failed prints, as the compounds required for curing break
      down and will not activate properly. The expiration date for resins is printed on the back
      of the bottle.
  4. Dispose of properly
    • Liquid resin should be cured before being disposed of. Pour liquid resin into a clear
      container and set it in direct sunlight. Once cured, it can be treated as waste and
      disposed of in regular trash.

 

Fabrication of Try-in Denture

 

Preparation Before Printing

 

Being prepared is key for success! As you plan to implement this new workflow, check
all the supplies and inventory you may need or desire for a seamless workflow.

    • Pro Printer
    • Pro Wash/Dry
    • ProCure
    • RayWare software
    • SprintRay Try-In 2 Resin
    • Gloves
    • (IPA) Isopropyl Alcohol 91% or higher
    • Scott Shop towels
    • Protective eyewear

Design of the Try-in Denture

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

  • Lingual Ridge ≥ 1.5 mm (Maxilla / Mandibula)
  • Palatal/Lingual ≥ 2.0 mm (Maxilla) / ≥ 1.5 (Mandibula)
  • Facial/Buccal ≥ 1.5 mm (Maxilla / Mandibula)

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°. Add supports. Remove all supports from the palatal intaglio surface but leave them on the flange perimeter.
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

 

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.

 

Post curing

Next, the printed Try-in Denture needs to be properly post-cured using a Pro Cure to maximize strength and accuracy and comply with FDA standards.


All the post-curing settings are preset in Pro Cure 1 and Pro Cure 2 units.
