Description
Pro3dure GR-14 denture materials are 3D printing resins for the generative production of denture bases. The printodent GR-14.2 denture HI meets all dental requirements with e.g. a water absorption (< 25 μg/mm3) and water solubility (< 1.5 μg/mm3) according to ISO 20795-1:2013. Furthermore, the low shrinkage (approx. < 1 %) compared to traditionally used PMMA-based materials guarantees a high accuracy of fit. printodent GR-14.2 denture HI is a 3D printing resin with “high-impact” properties characterized by low viscosity. This allows construction processes to be carried out efficiently and components to be cleaned easily.
All materials of the printodent GR-14 denture series can of course be combined with printodent GR-17.1 temporary lt to produce cost-effective and highly esthetic full dentures. In addition, validated procedures are available for the material in combination with denture teeth from the VITA VIONIC VIGO, CANDULOR TCR* / NFC+* and Ruthinium ACRYSMART systems. Complete integration in exocad‘s CAD software rounds off the digital workflow.
Advantages:
- high accuracy of fit
- ”high impact” material
- validated procedures

How to use
Preparation:
-
GR-14.2 denture HI bottles should be well shaken before use (Fig.1).
-
Make sure that GR-14.2 denture HI temperature is within 23 °C to 30 °C. If possible, always store a bottle GR-14.2 denture HI in your production unit in order to avoid temperature differences during refilling.
-
Impurities due to operational mistakes cannot be excluded. With respect to the low viscosity of the resin it is possible to filtrate GR-14.2 denture HI and stir it on a regular base (Fig.3). To avoid bubbles let GR-14.2 denture HI rest for 1 hour before usage.
Manufacturing process:
- Prepare data (CAD & build preparation).
- Choose process parameters (build style, etc.).
- Transfer prepared data to 3D printing device.
- Prepare 3D printing – shake bottle.
- Fill resin tank of 3D printing device (Fig.2). Bubbles can be removed with a clean spatula or by a recoater routine.
- Build the parts.
- Clean parts (with IPA ≥ 97 % or equivalent cleaning agent)
approx. 10 min. in an ultrasonic bath or equivalent
device – precleaning recommended. - Dry parts, until there are no residues of IPA or equivalent
cleaning agent. - Post curing (2 x 5 min. / wall thickness > 2.5 mm: 2 x 10 min.):
inert atmosphere recommended (use adequate light
curing device). - Finish parts. The dental objects created with GR-14.2 denture HI can be coated and repaired as usual.
Important
-
To avoid detrimental effects on material quality do not expose the liquid material to irradiation under any circumstances.
-
Deviations from the described manufacturing process may lead to different mechanical and optical properties of the GR-14.2 denture HI material.
-
Ensure personal protective gear during processing.
-
Caution: Polymerized resins are chemically resistant – avoid stains on clothing!
-
Avoid any contact with skin and eyes. In case of accidental contact, rinse with adequate running water, consulting a doctor if necessary.
-
The lot number and the best before date are indicated on each GR-14.2 denture HI packaging. In case of claims please always indicate the lot number of the product.
-
Do not use the product after expiry of the best before date.
