The metal bone screw rotation torque testing machine is specialized in testing the magnitude of its in and out torque values, and can also be used for self tapping performance testing of bone screws.

The screwing in torque and the unscrewing torque are collectively referred to as the turning torque. The screwing in torque is the torque required to overcome the frictional force between the screw and the test material when screwing the screw into the test material. The unscrewing torque is the torque required to overcome the frictional force between the screw and the test material when unscrewing the screw from the test material.

ISO/TS 13498 Dental Implant Systems - Torsion Test for Joint of Implants/Connections: This standard establishes a method for determining the torsional yield strength and maximum torque of intraosseous implant transplants/connections. This test is most suitable for evaluating new types of nodes and connection points, as well as new materials.
ISO 9917 water-based dental adhesives: ISO 9917 provides a detailed description and specification of the testing methods for dental adhesives. These dental adhesives are used as adhesives, seals, bases, punctures, and for some restorative purposes. The materials used for these dental adhesives are powder/liquid acidic adhesives.
ISO 6872 Dental Ceramic Bending Strength: This standard covers testing methods for dental ceramic materials used in fixed all ceramic and metal ceramic restorations and prostheses; The ISO 6872 bending strength test specification includes but is not limited to three-point or four point bending tests for ceramic dental restorations, crowns, veneers, implants, and stents.

Using the product:

Scope of application:

Suitable for different thread types (deep thread, full thread, half thread), different nominal diameters (HA/HB1.5-8.0mm), and different applications (cortical bone screws, cancellous bone screws, hollow screws). The metal bone screw in/out torque tester for bone joint implants is a multifunctional composite testing device tailored to the performance requirements of metal bone screws. It can be used for testing screw in/out torque, self tapping force, screw in/out force, torsional performance, and other related performance tests of bone screws.

test process

After the test is started, the upper fixture moves downwards at a preloading speed and applies axial pressure to the sample. When the axial pressure reaches the set value of the test load, the rotating motor starts and rotates at a torsional speed, recording the angle and rotationAfter completing the forward rotation test at 1440 °, the rotating motor continues to rotate in the opposite direction at 1440 ° to spin the sample out.

During the process of screwing in and out, the axial motor will adjust the load by lifting and lowering according to the feedback of the force value.

Test steps

1) Fix the prepared sample on the lower fixture and apply a suitable wrench to the upper fixture;

2) Set corresponding test parameters;

3) Fine tune the "up" or "down" position to make the axial pressure value lower than the preload, and align the specimen with the wrench. The specimen should be perpendicular to the measuring block;

4) Click the 'Start Experiment' button;
