* Selection of raw materials
Choose the best raw material–titanium sponge (grade 0 or grade 1)
* Advanced detection equipment
The turbine detector probes surface flaws above 3mm;
Ultrasonic flaw detection checks inner defects below 3mm;
Infrared detection apparatus measures the whole bar diameter from top to bottom.
* Test report with 3rd party

ASTM F67 is the standard specification for unalloyed Titanium, for Surgical Implant Applications(UNS R50250, UNS R50400, UNS R50550, UNS R50700), and the unalloyed titanium, namely pure titanium also applicable for ISO 5832-2 standard, Implants for surgery-Metallic materials-Part 2: unalloyed titanium.
Most implants titanium material use titanium alloy, but for dental implants use the unalloyed titanium most, especially for Grad 4.
