1. Process and manufacturing capabilities

o Precision machining: High-precision cutting of the tooth plate (such as CNC five-axis machining) to ensure the tooth shape, hole diameter and surface finish (Ra≤1.6μm).

o Heat treatment: Annealing or solid solution aging treatment is performed when necessary to eliminate stress and avoid deformation.

o Surface treatment: Anodizing, sandblasting or coating (such as titanium nitride) is selected according to needs to improve wear resistance.

2. MediTi Quality Control and Testing

Dimensional tolerance:
o Strictly check the key dimensions of the tooth plate (such as tooth pitch, center hole diameter), refer to the drawing tolerance (usually within ±0.05mm).
Non-destructive testing:
o Require ultrasonic flaw detection (UT) or X-ray testing to ensure that there are no internal defects (such as pores, inclusions).
o Surface penetrant testing (PT) to check for cracks.
Performance testing:
o Spot check hardness (usually HRC 30-36), fatigue strength (if used in dynamic load scenarios).

3.Our focus:

1. Biocompatibility (primary condition)

Non-toxicity: must comply with medical titanium alloy standards (such as ISO 5832-3 or ASTM F136) to ensure that no heavy metal ions are dissolved after implantation into the human body.

Corrosion resistance: long-term stability in body fluid environment to avoid inflammation or failure due to corrosion.

2. Mechanical properties (core function)

High strength and toughness: the typical tensile strength of TC4 (Ti-6Al-4V) must reach ≥860 MPa, while maintaining sufficient toughness (elongation ≥10%) to withstand the dynamic load of the spine.

Fatigue resistance: the implant must not fail under millions of cyclic loads, and stress concentration must be avoided in the threaded part of the toothed disc.

3. Processing accuracy (directly affects assembly and life)

Thread accuracy: the processing tolerance of the toothed disc thread must be controlled within ±0.02mm to ensure seamless fit with the titanium rod shrinkage or screws.

Surface finish: Ra (roughness) is usually required to be ≤0.8μm to reduce friction and wear.

4. Adaptability to clinical needsDesign compatibility

The geometry of the tooth plate (such as thread angle and pitch) must be fully compatible with the spinal screw system.

5. Intraoperative operability

The surgeon needs to be able to perform precise operations during implantation, so the edge processing of the tooth plate (such as chamfering) must avoid damaging surrounding tissues.
