Medical-grade titanium alloy dental discs (also known as dental titanium discs) are precision-machined disc blanks made of medical-grade titanium or titanium alloy, specifically designed for digital dental restoration. They serve as the core raw material for manufacturing dental implant abutments, crowns, bridges, and denture frameworks.
I. Material Standards and Grades
Pure Titanium (GR2, ASTM F67)
Purity ≥99.6%, low impurities
Optimal biocompatibility, excellent corrosion resistance, good toughness
Suitable for: Non-load-bearing / light-load restorations (braces, thin-walled crowns and bridges)
Titanium Alloy (GR5 ELI/GR23, ASTM F136)
Ti-6Al-4V alloy, high strength, high hardness
ELI (Extremely Low-Impurity) version: purer, safer
Suitable for: high-load restorations (implants, abutments, long bridges)
II. Key Performance Advantages
Top-tier biocompatibility
Non-toxic, hypoallergenic, and classified as Class 0 for cytotoxicity
The surface spontaneously forms a protective titanium dioxide layer that does not release metal ions
Promotes osseointegration, ensuring long-term implant safety and stability
Resistance to oral corrosion
Resistant to corrosion from saliva, food, and bacteria; never rusts
Better suited for the humid and complex oral environment than cobalt-chromium or stainless steel
Mechanical Properties
Lightweight and High-Strength: Strength comparable to steel, yet only 60% of the weight
Modulus of elasticity similar to bone, reducing stress shielding
Excellent machinability, compatible with CAD/CAM CNC machining
Precision and Stability
Forging + Precision CNC, tolerances **≤0.03mm**
Bright surface polish (Ra≤0.8μm)
Individual non-destructive testing, sterile packaging, medical-grade certification
III. Standard Specifications (Common)
Shape: Round disc (most common), square disc
Round disc dimensions: φ98 mm, thickness 10/12/14/16/18/20/22/25 mm
Condition: Annealed (M), free-cutting, stress-free
Surface: Bright turned / polished
IV. Clinical Applications
Implant Superstructures: Custom abutments, healing abutments
Fixed Restorations: Titanium base crowns, fully anatomical titanium crowns, long-span dental bridges
Removable Dentures: Titanium frameworks (lightweight, thin, comfortable, odor-free)
Orthodontic/Restorative Attachments: Implant pins, Locator attachments, inner crowns for sleeve crowns
In short, medical-grade titanium alloy abutments are a cornerstone material in modern digital dental restoration. Thanks to their safety, high strength, corrosion resistance, and precision, they have become the metal substrate of choice for dental implants and high-end dentures.
