Dental TC4/TA2 Titanium Rod | Core Technical Requirements

- Meet the standards for mass production of dental instruments and establish a solid foundation for clinical safety in oral restoration
 

Dental titanium rods, as the core material of dental restorations such as dental abutments, crowns, orthodontic brackets, etc., need to face the humid and corrosive environment of the oral cavity and the chewing and biting loads. Their quality directly determines the repair effect and patient comfort. We are based on the advantages of the entire industry chain of "China Titanium Valley", closely following the core procurement demands of dental instrument manufacturers. In response to the characteristics of dental titanium rods such as "biological affinity, fine size, and strong corrosion resistance", the company has clarified the key technical requirements for TC4 (high-strength demand) and TA2 (pure titanium basic demand) titanium rods, making procurement decisions more accurate, production more efficient, and products more compliant.

1. Compliance requirements: Oral level safety measures to eliminate registration barriers

Oral instruments come into direct contact with mucous membranes and blood, and registration review focuses on biosafety. Material compliance is the "first line of defense" for dental instrument manufacturers in procurement, which directly determines whether the product can enter dental clinical practice.

1. Full coverage of authoritative standards: Strictly follow GB/T 13810-2017 "Titanium and Titanium Alloy Processing Materials for Surgical Implants", ISO 5832-2/3 "Metal Materials for Surgical Implants", and ASTM F67 (Pure Titanium)/F136 (TC4) international standards to ensure that the materials can be directly used for implant abutments, orthodontic accessory production, and domestic and foreign registration applications such as NMPA, FDA, CE, etc., to avoid delays in the market cycle due to non-compliance with material standards.

2. Oral grade biosafety: TA2 pure titanium purity ≥ 99.6%, TC4 titanium alloy uses ≥ 99.7% high-purity sponge titanium as raw material, implements oral grade impurity control process - interstitial element oxygen ≤ 0.12% (TA2)/0.13% (TC4), nitrogen ≤ 0.01%, hydrogen ≤ 0.001%, to prevent oral reactions such as gum swelling and metal allergies caused by impurity precipitation from the root; Through ISO 10993 series biocompatibility testing (cytotoxicity, allergenicity, oral mucosal irritation test), third-party authoritative institutions issue qualified reports to meet the long-term implantation needs in the oral cavity.

3. Full process traceability: Each batch of products comes with a complete file of "raw material testing report+melting record+forging and rolling process parameters+finished product testing report", establishing a full chain traceability system from raw material batch to melting furnace number to finished product number, fully meeting the quality system audit requirements of dental instrument manufacturers and the full life cycle supervision requirements of oral implants.

2. Mechanical adaptability requirements: Match oral characteristics to ensure repair safety

Dental titanium rods need to withstand daily chewing (bite force of 200-800N) and complex oral environment erosion. TA2 and TC4 models are respectively adapted to different strength requirements, balancing functionality and comfort.

Additional guarantee: Strength and hardness fluctuations within the entire length range are ≤ 4%, and the grain size reaches ASTM grade 5 or above (TA2)/grade 6 or above (TC4), ensuring uniform performance of key parts such as implant abutment threads and crown edges, and avoiding intraoperative fracture or damage during use.

III. Requirements for Processing Adaptability: Meets dental precision technology and improves production efficiency

Dental repair instruments with precise dimensions (such as a base diameter of 2-5mm) require CAD/CAM digital processing, precision polishing, and other processes. The processing stability of titanium rods directly affects production losses and yield.

1. Micron level dimensional accuracy

The diameter tolerance is strictly controlled within ± 0.003mm, the straightness error is ≤ 0.02mm/m, and the diameter tolerance after centerless grinding reaches level h6. It is perfectly compatible with precision processes such as dental CAD/CAM system machining (dimensional accuracy ± 0.005mm) and implant abutment thread machining (pitch 0.5mm ± 0.005mm); The length and diameter can be customized according to the specifications of the restoration (such as commonly used diameters of 1-10mm), reducing material cutting waste and lowering production costs.

2. Double excellence in surface quality and corrosion resistance

-Surface requirements: No defects such as cracks, folds, scratches, etc. After mechanical polishing, the surface roughness Ra should be ≤ 0.4 μ m, meeting the oral hygiene standard. This not only reduces the wear of turning and milling tools, but also avoids periodontal problems caused by food residue adhesion;

-Corrosion resistance: A dense oxide film is formed on the surface, with a corrosion rate of ≤ 0.0005mm/year in saliva (pH 5.5-7.5) and disinfectant environments. TA2 pure titanium has better corrosion resistance and is suitable for long-term oral implantation. TC4 alloy has strong wear resistance and is suitable for areas with frequent biting.

3. Digital processing adaptation

The titanium rod has a uniform structure without segregation, and there are no chips or sticking during the cutting process. It is suitable for high-speed milling (speed above 15000rpm) and laser sintering processes in dentistry. After processing, the surface accuracy can reach Ra0.1 μ m, which can meet the appearance requirements of restorations without secondary polishing and improve the efficiency of digital production lines for dental equipment manufacturers.

Fourth, quality stability requirements: batch consistency, long-term reliability

Dental restorative instruments require extremely high consistency in appearance and performance, and the quality stability of titanium rods directly determines the reputation and repurchase rate of dental clinics.

1. Strict control of batch consistency: The composition, mechanical properties, and dimensional accuracy of titanium rods in the same batch fluctuate by ≤ 2%, and the difference between different batches is ≤ 3%, ensuring that dental instrument manufacturers do not need to frequently adjust CAD/CAM processing parameters to ensure the consistency of size and appearance in the mass production of restorations.

2. Long term performance stability: TA2 pure titanium is annealed at 300-400 ℃, and TC4 alloy is treated with "950 ℃/1h solid solution+600 ℃/2h aging", resulting in stable structure and long-term service (≥ 10 years) in the oral environment without deformation, corrosion, or performance degradation, meeting the long-term repair needs of dental implants and other treatments.

3. Zero release for full testing: Each batch of products undergoes spectral composition analysis, ultrasonic non-destructive testing (internal defects ≤ Φ 0.3mm equivalent flat bottom holes), tensile testing, and surface roughness testing. Critical batches are additionally subjected to saliva immersion corrosion testing, and no defective products enter the market.
