VITA VIONIC^® BASE RESIN FLEX

VITA recommends the following procedure for vacuum-based, validated devices (such as the Asiga Cure or RapidShape Cure):

Step 1: ​

Secure the printed teeth in the denture base using a light-curing UV hand lamp, provided that you are using the printing material as an adhesive. It is sufficient to irradiate the areas between the tooth and the base for a few seconds.

Step 2:​

Complete curing in the device using the VITA template.

Yes, printed clasp dentures made from VITA VIONIC BASE RESIN FLEX can be repaired and extended.

VITA recommends the following materials and procedures for this purpose:

• For the shade pink translucent: Astron Labtec Pro
• For the shade clear: Astron Clearsplint

1. Sandblasting with Al₂O₃ (50 µm, 2 bar)
2. Application of VITA VM LC Primer II to condition the denture base.
3. Apply a thin, even layer using a disposable brush. Then cure with an approved light-curing device in accordance with the polymerization instructions for VITA VM LC Primer II.
4. Application and processing of Astron Clearsplint or Astron Labtec Pro according to the manufacturer's instructions.

Repairs using classic cold polymer are also possible in principle. However, the rigid material can impair the flexibility of the partial denture, thereby reducing the expected service life of the denture.

The Otoflash G171 N2 has been validated for VITA AKZENT LC with a UV filter type 280 N2. This filter transmits wavelengths from 280 to 700 nm.

VITA VIONIC BASE RESIN FLEX is compatible with a wide range of commonly used printers and post-curing units. A current list of successfully validated devices can be found on the product page under the "System compatibility" tab or at the following link: VITA VIONIC RESIN | Validated devices

The material thickness determines the flexibility of the partial denture. The finer the clamp design, the more flexible it reacts, while a stronger design provides more stability.

• Clamps: Ideally 1-1.5 mm
• Minimum wall thickness of tooth pockets: 0.8-1 mm
• Bonding gap for teeth: 150µm
• Palatal: 2-3 mm
• Sublingual: 3-5 mm

The cleaning process is carried out by dental laboratories/dental practices in an ultrasonic bath (room temperature water bath). Do not use heat-based disinfection or sterilization methods. This could cause the denture to lose its shape.

Brief immersion disinfection is possible without any problems, provided that ethanol-based disinfectants are not used.

For daily cleaning of the dentures, the patient should use lukewarm water, a soft toothbrush, liquid soap or dishwashing liquid. Rinse well afterwards. Denture cleaning tablets can be used according to the manufacturer's instructions.

Notes: Do not use toothpaste, as the abrasive particles are coarse and will scratch the dentures. Do not use acids or solvents, as these will deteriorate the material properties when applied.

Aus 1 kg VITA VIONIC BASE RESIN FLEX können ca. 606 flexible Klammerprothesen gedruckt werden, welche eine Größe von 1-2 zu ersetzenden Zähnen haben und in eine kleine Schaltlücke passen.

Die tatsächliche Anzahl gedruckter Objekte, die mittels 1kg Harz hergestellt werden können, ist von mehreren Faktoren abhängig wie z.B. der Größe der Klammerprothese, der Anzahl an Stützstrukturen und ob das Harz in der Druckwanne gelagert wird bzw. Materialverluste beim Abtropfen entstehen.
