Pro3dure Printodent Denture Base




The Pro3dure Denture Base resin is a light-curable polymerizable resin intended to be used with
extraoral curing light equipment. The Denture Base resin is indicated for the fabrication and
repair, by additive manufacturing, of full and partial removable dentures and baseplates.
Pro3dure Denture Base resin is offered in following shades: Original and Dark.
The material is an alternative to traditional denture base material. Pro3dure Denture Base Resin
is intended exclusively for professional dental work.
Fabrication of dental applications with Pro3dure Denture Base 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 Denture Base 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

Denture Base 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:

  1. 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.
  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. 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
  4. 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.
  5. 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.

  • OptiGlazeTM (Optional)

Design for the Denture

Once the intraoral scans of the patient/dentures are submitted to a dental-design
service/lab, the denture base is designed and provided in STL file format by the dental design service/lab.

Make sure:
Lingual Ridge ≥ 2.5 mm (Maxilla / Mandibula)
Palatal/Lingual ≥ 3.0 mm (Maxilla) / ≥ 2.5 (Mandibula)
Facial/Buccal ≥ 2.5 mm (Maxilla / Mandibula)


Bring the designed STL files to RayWare. Position the Intaglio surface of the 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
Select “Pro3dure Denture Base” resin setting for print-setting and use 100-micron


Washing and Drying

After your Denture Base has been printed successfully, it must be washed using Isopropyl Alcohol (IPA) with a concentration of 91% or higher before being post-cured. Pro3dure 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 Denture Base 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 Denture Base is completely dry before the next step; if not, use compressed air to dry your Denture Base rapidly. Remove the Denture Base from the Print Platform.

Support Removal

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 Denture Base to minimize the smoothening and polishing procedure.


Assembling the Denture and Post-Curing

Now that the Denture Base is printed, the next step is to bond the teeth to it. You may use printed denture teeth or conventional prefabricated artificial teeth. Use a syringe or pipette to place a drop of the Denture Base resin in each tooth socket on the Denture Base, place the teeth on the sockets, and press firmly to fit the teeth in the sockets. Use a curing light to tack cure the assembled denture base and teeth. Next, they need to be properly post-cured using a ProCure to maximize strength and accuracy, and to comply with FDA standards. You need to post-cure for 30 minutes at 50° C degrees. To obtain the optimal bonding of artificial teeth to the dental object, it may be necessary to roughen the surface of the denture/teeth sockets.


Finishing and Polishing


Use the Scotch-BriteTM/FuzziesTM Wheel for smoothening the denture surface, followed
by using pumice & polishing compound and muslin wheel to polish the surface. You may
use a pink compound-bar and a cotton buff for a mirror finish.

This is an optional step to give a better and more realistic look to the teeth or even
denture. Characterization helps to provide the denture a better and more natural look by
staining and glazing, which allows to change shades, shift value, characterize, create
effects and glaze to achieve a more beautiful and esthetic denture.
You may use the OptiGlaze™ kit by GC for a better cosmetic effect. Light cure the
OptiGlaze colors and stains on the denture teeth and/or base. You may combine
multiple colors to make the desired color

We can help with that!
