Introduction
The document discusses the advantages of Ref-line teeth, a product by Polident d.o.o., designed to mimic natural teeth using advanced technology and materials.

Development and Design
Ref-line teeth were developed by an in-house dental technician in collaboration with tool-makers. The design focuses on natural tooth shapes, surface texture, and internal layering, ensuring a realistic appearance. The teeth incorporate high anatomical shapes derived from natural teeth, with detailed modeling for optimal aesthetics.

Material and Production
The teeth are made from a new composite acrylic material, featuring pre-cross-linked polymer and inorganic nano- and micro-fillers. This composition enhances mechanical wear resistance by 50%, increases hardness by 15%, and maintains elasticity. The material also offers good resistance to plaque adhesion, color stability, and excellent polishing properties.

Innovative Features
Ref-line teeth include a new layering and shading system, allowing for high customization and color effects. The design minimizes the need for grinding, saving time during setup. The bottom opening of posterior teeth aids in modeling retentions for implant-supported dentures.

Achievements
The main achievements of Ref-line teeth include a natural look, high color stability, and no cracking due to the use of silanized composite particles. The advanced tooth molds prevent air bubbles and material shrinkage, ensuring consistent quality and repeatability.

Conclusion
Ref-line teeth offer a combination of natural aesthetics, advanced materials, and innovative production techniques, making them a superior choice in the range of anatomic multi-layer composite teeth.
