Tooth torsion yield tester

Applicable standards:

YY/T 0315-2016: This standard may specifically address certain performance requirements for titanium and titanium alloy dental implants, including test requirements for torsional yield strength.

ISO TS 13498-2011: This standard deals with torsion testing of joint component implants/joint joint joints for dental intraosseous implant systems, which may include testing requirements for the torsional yield strength of dental implants.

Main parameters:

Torque measurement range: This parameter determines the maximum torque value that the tester can measure. Common torque measurements may range from a few Newton ·m （N·m） to a dozen Newton ·m, depending on the tester model and manufacturer.

Torque measurement accuracy: This parameter indicates the accuracy of the tester when measuring torque. High precision is the key to ensure the reliability of test results. Common torque measurement accuracy may reach ±1% or higher, the actual accuracy may be higher, such as ±0.5% or more.

Torsion Angle measurement range: This parameter determines the maximum torsion Angle that the tester can measure. Common torsion Angle measurements can range from 0° to hundreds of thousands of °, depending on the tester model and manufacturer. Some testers may also offer the option of infinite torsion angles.

Resolution: This parameter indicates the minimum resolvable value of the tester when measuring torque and torsion Angle. The high resolution allows for a more precise understanding of how the material's properties change during torsion. Common resolutions can reach extremely small values, such as 0.000002Nm （torque） and extremely small angular values （torsion Angle）。

Test speed: This parameter determines the rotation speed of the tester during the test. Common test speeds can range from a few degrees per minute to thousands of degrees per minute, depending on the tester model and manufacturer. The choice of test speed should be determined according to the specific test requirements and material characteristics.

Fixture: The fixture is one of the key components of the tester and is used to fix and clamp the sample. High-quality fixtures should have good durability and stability to ensure accuracy and reliability during testing. Common fixture materials may include high-strength materials such as stainless steel.

Control system: This parameter determines the degree of automation and test efficiency of the tester. Modern testers usually use advanced control systems, such as PLC （programmable logic controller） or microcomputer control, to achieve automatic control and data acquisition. These control systems help improve the accuracy and efficiency of the test.

Display and recording: The tester is usually equipped with a color touch screen display and recording system, supporting functions such as Chinese and English menu operation and data export. These features make it easy for users to set test parameters, view test results, and export test reports.
