Introduction
The document introduces Prettau® Skin®, a minimally invasive restoration technique using ultra-thin zirconia veneers. This method is designed to provide aesthetic dental corrections with minimal impact on tooth substance.

Specifications
- The restoration involves monolithic veneers, partial crowns, and a three-unit bridge made from Prettau® 2 Dispersive® zirconia.
- Tooth shade is determined using the Zirkonzahn Shade Guide Prettau® 2 Dispersive®.
- Virtual model articulation is performed using MDT Udo Plaster’s PlaneSystem®.
- The process includes the use of AIDA from the virtual library Heroes Collection.

Procedures
- Determination of optimal insertion direction for block-out model creation for mock-ups.
- Nesting and milling of mock-ups in a Temp Premium Flexible resin blank, followed by patient try-in.
- Communication tools guide dental technicians in suggesting tooth areas for preparation.
- Minimally invasive tooth preparation is conducted.
- Design and milling of ultra-thin veneers (0.2 mm), partial crowns, and a three-unit bridge using Prettau® 2 Dispersive® zirconia.
- Sintering and characterisation are done with ICE Stains 3D by Enrico Steger.

Features and Benefits
- The technique allows for aesthetic correction of discolourations, gaps, crooked, cone, and abraded teeth.
- Prettau® 2 Dispersive® zirconia offers a natural colour gradient, optimal flexural strength, and high translucency.
- The monolithic design prevents ceramic chipping and antagonist abrasion.
- Custom characterisation is possible with Colour Liquids Prettau® Aquarell Intensive, ICE Ceramics, Fresco Ceramics, and ICE Stains 3D.

Technology and Equipment
- The M2 Milling Unit Comfort Line features a larger milling area with diameters of 125, 106, 98, and 95 mm.
- The unit is fully automatic, flexible, and vibration-free, suitable for various dental restorations.

Conclusion
The Prettau® Skin® technique represents an advancement in dental restoration, offering a minimally invasive solution with high aesthetic value and durability.
