DENTCA Denture Base II contains polymerizable monomers which may cause skin irritation (allergic contact dermatitis) or other allergic reactions in susceptible persons. 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.

BURN HAZARD: GLYCEROL BATH CAN REACH TEMPERATURES OF 90 oC (~200 °F) AND LEAD TO SEVERE BURNS. Only trained users should perform the glycerol curing step with caution and appropriate PPE. We also recommend placing a warning label on the window of the cure unit to alert all lab users to the potential hazard.



  1. When washing the printed denture bases with solvent or grinding the denture bases, it should be in a properly ventilated environment with proper protective masks and gloves
  2. Store DETCA Denture Base II at 15 -25°C(60 - 77°F) and avoid direct sunlight. Keep container closed when it is not in use. Product shall not be used after expiration date.
  3. Expired or unused DENTCA Denture Base II should be completely cured or polymerized prior to disposal


Adverse Reactions:

  1. Direct contact with the uncured resin may induce skin sensitization in susceptible individuals
  2. Proper ventilation and personal protective equipment should be used when grinding denture base resins as the particulate generated during grinding may cause respiratory, skin, or eye irritation



Procedure to Fabricate Denture

Printing Preparation

  1. Select the denture base shade based on prescription. (Recommended to use the
    different resin tank for the different shade.)
  2. Open the 3D printer cover and fill the resin tank of the printer with fresh DENTCA
    Denture Base II up to the required filling line by manufacturer. (When filling the resin
    into the resin tank, gloves and mask should be used.)
  3. Close the printer cover.



  1. Load the denture base model file to be printed in printer operation software which
    printer manufacturer recommended.
  2. Use auto-orientation or manual orientation to find its optimal position for printing. The
    recommended orientation by printer provider is a tilted orientation such as space
    diagonal from 20 to 90 angle. If auto-orientation is not satisfied, rotate to make optimal position.
  3. Generate support structures on the denture base using the recommended setting by
    printer provider such as support contact size and support density. (Avoid the support structures inside the tooth socket area and the ridge area. If some of supports are generated inside the teeth sockets and on the ridge area, either relocate it to the edge of denture base or remove it.
  4. Use layout tools of the software to move the denture base model within the imaginary
    build platform to prevent the overlapping between models.
  5. Start printing.


  1. Detach the printed denture base from the build platform.
  2. Use a small flush cutter to remove the support sticks from the denture base.
  3. Wash the denture base with isopropyl alcohol.
  4. Use a paper towel to dry the denture base or dry it at room temperature under
    ventilation system or open area.

Denture Fabrication using a printed denture teeth and base

Bonding the printed teeth to the printed denture base

  1. Prepare, before post-cured, the printed teeth and printed denture base with socket shapes
    to receive printed teeth (Tooth Sockets).
  2. Place the printed teeth with DENTCA Denture Teeth into the corresponding Tooth Sockets
    on the printed denture base and check teeth fitting
  3. Apply small amount of light curable adhesive into the Tooth Sockets and bond the teeth by
    exposing into UV light until the teeth is set in position. Recommend using DENTCA Denture
    Base II for bonding.
  4. If necessary, apply small amount of DENTCA Denture Base II using an applicator to
    smoothen the edges of the denture base and cure it.
  5. Add denture base material manually on the lingual ridge area to thicken and cure it. It is
    recommended to make it thicker than 4.0mm for maxillary and 4.5mm for mandibular

Post Curing

  1. Cure the final denture by sinking into the glycerin container (glycerin temperature should be
    greater than 60°C and it is recommended to be replaced every 80 hrs of running or every
    three months whichever comes first.) for the required curing time under recommended
    post-curing unit. For half of the post-curing time tissue shall side up and for another half of
    the time tissue shall side down. (For Dentalfarm PHOTOPOL A5408D, pre-heating the curing
    unit with glycerin for 2 hours before post-curing is required.)
  2. Take out the printed denture from the curing oven using coated tong (Be careful of hot glycerin!).
  3. Rinse the cured denture with a water.


  1. Smoothen the support spots on the denture base using a bur.
  2. Polish the final denture with wet polishing sand by conventional method.

Repair of denture and baseplates

Note: This process is only applied to temporary repair cases. It is recommended to remake the
whole denture using an original design file.

  1. Prepare a cast made of a putty using a broken denture.
  2. Prepare the fracture area by grinding to open more and roughing the outer side of fracture area.
  3. Prime the roughened surfaces of the repair area with DENTCA Denture Base II.
  4. Place the broken denture on the cast.
  5. Apply the DENTCA Denture Base II resin to cover the roughed and fracture areas and cure the areas by exposing light curing machine until the resin is solidified.
  6. Place the denture on the cast in the post-curing machine for the half of required time. Carefully remove the denture from the cast and cure the tissue side for the half of required time.
  7. Grind, polish and finish.
