All-on-X ZR are full-arch zirconia restorations designed for completely edentulous patients or cases with advanced tooth loss. These restorations are supported by four, six, or more implants. Developed for patients with high aesthetic expectations, this system combines the biocompatibility of zirconia with modern digital manufacturing technologies and does not include a metal framework.

All-on-X ZR restorations produced in our laboratory are designed to achieve highly natural aesthetics while prioritizing functional stability and long-term clinical reliability.

What Is the All-on-X ZR (Zirconia) System?

In All-on-X ZR systems, the main body of the restoration is fabricated from zirconium dioxide, a material known for its high strength and excellent light transmission. The term “X” refers to the number of implants supporting the restoration, such as All-on-4 or All-on-6, while “ZR” indicates that the framework is made entirely of zirconia.

Because the system does not contain a metal framework, there is no risk of discoloration or gray shine-through at the gingival margin. This characteristic makes All-on-X ZR restorations especially suitable for patients with thin gingival biotypes and high smile lines.

Clinical and Aesthetic Advantages of All-on-X ZR Restorations

• Superior aesthetics and a natural appearance: The light-transmitting properties of zirconia provide an optical result that closely resembles natural enamel. The absence of dark reflections at the gingival margin helps maintain long-term aesthetic continuity.

• Maximum biocompatibility: Zirconia exhibits excellent compatibility with oral tissues. It is a safe option for patients with metal allergies and supports healthy gingival tissues.

• High mechanical strength: Next-generation high-translucency zirconia materials offer superior resistance to the masticatory forces encountered in full-arch restorations.

• Lightweight structure and patient comfort:
  Compared to metal-supported systems, zirconia restorations are lighter, which helps patients adapt to the prosthesis more quickly.

• Precise digital fit: Restorations manufactured using CAD/CAM technology provide high accuracy and reliable compatibility with implants and multi-unit abutment systems.

Our Digital Production Process for All-on-X ZR Restorations

Successful full-arch zirconia restorations begin with accurate planning. For this reason, our production workflow is based on controlled and fully digital protocols.

1. Digital analysis and design: Implant positions, vertical dimension, and aesthetic parameters are digitally analyzed using impressions and scans provided by the clinician.

2. Monolithic or layered zirconia selection: Monolithic zirconia is preferred for cases with high functional demands, while layered zirconia is used in cases with elevated aesthetic expectations.

3. Five-axis precision milling: Multilayer zirconia blocks are milled using high-precision five-axis milling machines to produce accurate and consistent frameworks.

4. Pink aesthetics and characterization: When required, specialized porcelains are applied over zirconia to create natural gingival contours and smooth color transitions.

Which Cases Are Best Suited for All-on-X ZR?

All-on-X ZR restorations are an ideal solution for patients with high aesthetic expectations, those seeking a metal-free treatment option, and cases in which long-term biocompatible materials are preferred.

When combined with proper case selection and appropriate occlusal planning, All-on-X ZR systems deliver predictable and highly satisfying results for both clinicians and patients.
