Dental specific titanium alloy disc TC4/TC4ELI precision substrate for oral restoration
As the core product of Baoji Dingding Titanium's deep cultivation in the field of oral medicine, the dental special titanium alloy disc focuses on the two major grades of medical grade TC4 and TC4ELI, focusing on the substrate needs of denture processing, dental implant abutments, and personalized oral restoration instruments. Relying on medical grade titanium precision machining technology, our products have excellent biocompatibility, stable mechanical properties, and ultra-high machining accuracy. They have passed ISO 13485 medical device quality management system certification and comply with ASTM F136 and GB 4234.1-2017 medical standards. We have become a strategic supplier for domestic and foreign dental device manufacturers and denture processing centers, helping oral restoration solutions achieve precision and personalized upgrades.
1. Core Advantage: Exclusive Characteristics of Dental Medical Grade Titanium Materials
1. Excellent biocompatibility, suitable for complex oral environments
TC4ELI is an ultra-low gap element medical titanium alloy that does not contain allergenic components such as nickel and chromium. After implantation in the oral cavity, the tissue rejection rate is ≤ 0.02%, far below the industry average level; Excellent corrosion resistance, able to withstand long-term saliva and food acid-base erosion, with a corrosion rate of ≤ 0.0001mm/year, and high adhesion to gingival tissue, ensuring long-term use safety.
2. Rich and adaptable specifications to meet diverse repair needs
The size specifications cover mainstream industry standards and are suitable for various oral restoration scenarios: diameters of 95mm, 98mm, 100mm, 130mm, etc. are commonly used specifications, taking into account the processing needs of conventional dentures and large restoration instruments; There are various thickness options available, including mainstream sizes such as 12mm, 14mm, 16mm, 18mm, 20mm, etc., which can be flexibly selected according to denture types, implant specifications, and personalized restoration needs. Regular specifications are available in stock without long waiting times.
3. Precise dimensional control, empowering efficient machining
Adopting the full process technology of "vacuum melting+precision forging+CNC turning", the diameter tolerance is controlled within ± 0.1mm, the thickness tolerance is ± 0.05mm, the flatness is ≤ 0.08mm/m, the surface smoothness Ra is ≤ 0.2 μ m, there are no burrs or oxide layers, and the denture processing procedures such as cutting, drilling, and polishing can be directly carried out, greatly improving the processing efficiency and product qualification rate, with a processing qualification rate of 99.8%.
4. Matching mechanical properties, balancing strength and toughness
TC4 has a tensile strength of ≥ 860MPa and an elastic modulus similar to that of human alveolar bone. When subjected to stress, the stress distribution is uniform, avoiding damage to natural teeth and suitable for conventional denture processing; TC4ELI has an elongation rate of ≥ 18%, superior toughness, and is suitable for complex oral restoration instruments and high demand implant abutment molding, meeting the strength and stability requirements for long-term chewing use.

III. Medical Quality Control System
1. Raw material traceability control
Using medical grade sponge titanium that meets the GB 2524-2019 standard, the TC4ELI grade interstitial element (Fe, O, N) content is strictly controlled within the industry's strict standards. Each batch of raw materials is accompanied by an ICP-MS full element analysis report, and a raw material traceability file is established to ensure source safety.
2. Production process
Equipped with specialized processing equipment and technology for dental titanium materials to avoid cross contamination with industrial grade titanium materials; The finished product undergoes ultrasonic cleaning and can directly enter the dental processing stage.
3. Full dimensional testing and certification
Each batch of products has undergone testing for dimensional accuracy, surface smoothness, mechanical properties, and biocompatibility (cytotoxicity, allergenicity, irritation) through random sampling; Through ISO 13485 certification, it meets the oral medical access standards of multiple regions such as China NMPA, US FDA, and EU CE.
