Titanium Alloy Disc (140×150mm Large Format) for Full-Arch Restorations

The Bokang Dental Titanium Alloy Discs (140×150mm) are manufactured in GR5 and GR23, in a large-format design specifically developed for full-arch implant bridges, complex multi-unit frameworks, and large-scale restorations.

With high tensile strength and a significantly larger diameter than standard 98mm discs, these discs enable one-piece fabrication of extensive frameworks without splicing or welding. Available in 8 thickness options (10–25mm), they provide flexibility for a wide range of full-arch and complex prosthetic applications.

Key Features

• Large Format 140×150mm Diameter
  Significantly larger than standard 98mm discs, allowing one-piece full-arch frameworks without splicing.
• GR5 (Ti-6Al-4V) / GR23 (Ti-6Al-4V ELI) Titanium Alloy 
  Medical-grade materials with high strength, excellent biocompatibility, and long-term stability.
• Optimized for Full-Arch Restorations
  Suitable for All-on-4/6/8 implant bridges and large multi-unit frameworks.
• Improved Material Utilization
  Larger format reduces waste and supports efficient nesting of multiple components, with material utilization typically 70–85%.
• One-Piece Framework Capability
  Eliminates welding and joining steps, improving accuracy and reducing production time.
• CAM System Compatibility
  Compatible with professional systems such as Roland DWX-52D/52DC, Wieland Zenotec, VHF K5/K6, and Amann Girrbach Ceramill Motion 2.
• Multiple Thickness Options (10–25mm)
  Suitable for applications from thin frameworks to full-arch structures.
• Dual-Phase Microstructure (α+β)
  Ensures stable mechanical properties and good machinability for complex geometries.

Recommended Applications

• Full-arch implant bridges (All-on-4 / 6 / 8)
• Large multi-unit bridges (5+ units)
• Implant frameworks, overdenture bars, and hybrid prosthetics
• Screw-retained full-arch restorations
• Large partial denture frameworks
• Batch production of multiple crowns or abutments
• Custom implant superstructures

Advantages Over Standard 98mm Discs

• Size Advantage: ~21,000 mm² vs ~7,500 mm² — nearly 3× larger working area
• One-Piece Full-Arch Milling: Mill complete frameworks without splicing
• No Welding Required: Reduces fabrication steps and potential weak points
• Higher Material Efficiency: Better nesting reduces waste and improves yield
• Improved Accuracy: Avoids alignment errors from segmented frameworks
• Flexible Production: Supports both large frameworks and multiple smaller restorations
