WallaBC Acrtal Splint FLEX blanks are made of a thermoplastic copolymer based on a medical-grade PETG. The material is characterized by high flexibility and simultaneously high impact strength. Free of toxic and allergenic substances, it is ideal for patients with intolerances. Using CAD/CAM technology, you will achieve a perfect fit with no re-machining.
Benefits:
Biocompatible – medical thermoplastic
High level of flexibility
Good polishing properties
Possible to bond to conventional polymers (with a bonder)
Bisphenol A and monomer-free

| Fracture toughness | [MPa m1/2] | ≥ 3 |
| Water sorption | [µg/mm³] | 6 |
| Solubility | [µg/mm³] | < 0,25 |
| Available Thickness |
12 14 16 18 20 22 25 30mm |
| Available Colors | Vita 16 Colors | Bleach Shades | Clear | Pink |
| Available Types |
98mm for Open System | 95mm | 71mm D Shape |
| Indications | Flexible splints, therapeutic splints, bite regulators, drilling templates (Indicated for short-term use in the oral cavity) |
The shoulder shall not be prepared in the area of corner and sharp edge. The shoulder shall be prepared in the shape of a round inner edge or inclined surface.
The space of 1mm is required to be reserved for the preparation of the cutting edge, so as to ensure that the PMMA block can achieve the ideal grinding effect in the process of CAD / CAM. The preparation of the cutting edge should be at the enamel layer, and avoid the preparation at the point or area of stress concentration.

Clinical Guide
Walla™ C14 — Indicated restoration types and recommended suitability ratings
The top aesthetic choice. Ultra-thin machinability combined with fluorescence and chameleon optics perfectly reproduce natural tooth light dynamics for anterior smile enhancements.
Ideal for preserving healthy tooth structure. The 420 MPa flexural strength ensures inlays withstand occlusal loading without fracture, while natural aesthetics blend seamlessly.
Combining aesthetics and strength, C14 is the premier choice for anterior all-ceramic crowns. Natural shade transitions ensure seamless integration with adjacent dentition.
Suitable for premolar and molar single crowns. The 420 MPa strength handles normal masticatory loads — patient occlusal assessment recommended before placement.
Limited to 3-unit bridges up to and including the premolar region. Connector cross-section must meet design specifications — consult your laboratory to confirm design feasibility.
Brand Promise
We don't just sell a product — we stand behind every restoration and every patient's trust.
Every batch of Walla C14 undergoes accelerated aging tests and strength sampling inspections to ensure consistent batch-to-batch performance. We reject "good enough" — because a restoration must perform reliably for ten years or more.
Whatever milling system your practice uses, Walla C14 has been validated through real-world testing. Excellent milling efficiency right out of the box — no special parameter adjustments required for major CAD/CAM platforms.
As the core brand of WallaBC, we go beyond the product — offering professional technical guidance and after-sales support. From milling parameters to firing curves, our technical team is always ready to assist.
