Confidentially plan implant-supported prosthetics with accurate soft tissue replicas
Gingiva Mask is a flexible yet firm material intended to be used in combination with SprintRay model materials to mimic the look and feel of natural gum tissue. Gingiva Mask has a high tear resistance and is easy to trim for optimal restorative planning
- Excellent Tear Resistance
- Flexible material that allows for easy trimming
- Biocompatible, FDA-compliant material
Instructions For Use
The SprintRay Gingiva Mask resin is a light-curable polymerizable resin intended to be used with extraoral curing light equipment. The Gingiva Mask resin is indicated for the fabrication, by additive manufacturing, of gingival replica for a better and more accurate dental model representation.
SprintRay Gingiva Mask Resin is intended exclusively for professional dental work.
Fabrication of dental applications with SprintRay Gingiva Mask Resin requires a 3D design of the custom device designed by a qualified provider. It also requires a 3D Printer and Cure System to produce the devices.
The Gingiva Mask 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
Gingiva Mask Resin is non-toxic in both liquid and solid form, and it is classified as Biocompatible material, approved by FDA. 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:
- Always wear gloves
Always wear gloves when handling uncured resin. Whether you are pouring, removing models from the platform, or even after models have been washed, must wear gloves to limit exposure to resin.
- 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.
- Filter resin
When pouring resin from your tank or other vessels back into the bottle, always pour through a fine mesh filter. This will trap partially cured debris and prevent contamination of the rest of your bottle, prolonging the life of your materials.
- 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.
- Dispose of properly
Liquid resin should be cured before being disposed. 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 the regular trash.
Fabrication of Gingiva Mask
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/DryTM
- RayWare software
- SprintRay Gingiva Mask Resin
- (IPA) Isopropyl Alcohol 91% or higher
- Scott Shop towels
- Protective eyewear
- Flush cutter
- Scotch-BriteTM/FuzziesTM Wheel
Design of the gingiva mask
Once the intraoral scans of the patient are submitted to a dental-design service/lab, the gingiva mask is designed and provided in STL file format by the dental-design service/lab.
Make sure to meet the minimum of 0.4 mm wall thickness.
Bring the designed STL files to RayWare. Position the gingiva mask parallel to print platform, make sure the tissue side is towards print platform (facing down).
Add full supports. Avoid having any support at the edges and any critical anatomy.
Select “SprintRay Gingiva Mask” resin setting for print-setting and use 100-micron thickness.
Make sure 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 gingiva mask 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 a dish for soaking along with a Soft/Medium bristle brush to manually clean your prints in IPA. Make sure NOT to immerse the Gingiva Mask 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 gingiva mask is completely dry before the next step; if not, use compressed air to dry your gingiva mask rapidly.
Remove the gingiva mask from the Print Platform.
Next, the printed gingiva mask needs to be properly post-cured using a ProCure to maximize strength and accuracy and comply with FDA standards.
All the post-curing settings are present in ProCure 1 and ProCure 2 units.
Once the post-curing is completed, we need to remove all the supports by using a flush cutter. Try to cut as close as possible to the gingiva mask to minimize the smoothening and finishing procedure.
Finishing and Polishing
Use the Scotch-BriteTM/FuzziesTM Wheel for smoothening the gingiva mask surface.
