Introduction
The document outlines the technical specifications and procedures for creating a full arch bridge for the mandible using Prettau® 3 Dispersive® zirconia on an anodised titanium bar. This process involves advanced digital and milling technologies provided by Zirkonzahn.

Specifications
The Prettau® 3 Dispersive® zirconia is designed with a Gradual-Triplex-Technology that incorporates a natural color gradient, increasing translucency incisally, and high flexural strength cervically. The zirconia is suitable for monolithic designs, reducing the risk of ceramic chipping.

Procedures
The process begins with a digital mounting of the oral situation using a 3D facial scanner and the PlaneSystem®. The titanium bar is designed using Zirkonzahn.Modellier software, followed by milling and digitization. The zirconia structure is positioned using Zirkonzahn.Nesting to optimize the color gradient alignment. The Prettau® Bridge is milled in the M2 Dual Teleskoper milling unit and sintered at 1500°C. The final steps include glazing and minimal veneering of the gingiva.

Technological Features
The M2 Milling Unit Comfort Line offers a larger milling area with diameters of 125, 106, 98, and 95 mm, providing flexibility and vibration-free operation. The Prettau® 3 Dispersive® material is characterized by its high flexural strength (~1100 MPa cervically, ~670 MPa incisally) and translucency gradient.

Applications and Recommendations
This zirconia is indicated for reduced or monolithic single crowns, inlays, onlays, veneers, and bar-supported multi-unit bridges. It is particularly suitable for monolithic designs and can be individually characterized for each patient using various ceramic and stain options.
