.

Assemble and assemble the implant abutment according to the manufacturer's instructions, tighten the central screw or implant abutment with a wrench, until the torque tester reaches 120% of the value specified in the manufacturer's technical documents, keep the load for 5 s, and observe the dental implant with the naked eye.
and supporting parts, shall not be deformed or broken
.

Loosen the central screw or implant abutment with a wrench in the opposite direction, and read the maximum torque during the loosening process on the torque meter
.

Measure 3 dental implants of the same model, and the 3 measurement results shall comply with the provisions of 5.
6.
2: After applying the maximum tightening torque, observe the dental implants and supporting parts with the naked eye, and no deformation or fracture occurs
.

The maximum loosening torque should be more than 75% of the maximum tightening torque
.

Product introduction: YY0315 dental implant anti-tightening torque tester bone screw performance tester Torque Tester Bone Screw Performance Tester Screw mechanical performance tester can perform related tests on bone screw rotation torque, self-tapping performance, pull-out force, and torsion performance
.
Bone screw performance tester can be widely used in medical device testing institutions, scientific research institutions and medical device manufacturers
.

Product features: ● Open structure, friendly man-machine interface operation, multiple sets of curve drawing modes, the test process is clearer ● Driven by precision differential motor, the transmission is more stable, the noise is lower, the positioning is more accurate, and the test results are more repeatable ● Imported customized high-sensitivity load cell, imported (TBI) lead screw to ensure accurate displacement ● Professional high-performance imported control system controls the coordinated action of dual servo motors ● Fully automatic measurement ● Simple and easy to operate, highly simplified control system puts all tedious settings in the background Complete, one-button start ● Professional fixtures are suitable for different test modes ● Built-in special calibration program, which is convenient for measurement and calibration departments (third parties) to calibrate the instrument ● 18-inch high-definition touch screen control, support data export and Office software, combined with optimized integration Data processing system ● Diversified functions, one machine to achieve: pull-out performance, self-power performance, rotational torque, torsion performance Technical parameters: force value measurement range 20kg pull-out force measurement range ≤ 200kg torque measurement range 0-3Nm measurement accuracy 0.
