Testing of Herbert compression screws

EndoLab internal test procedure PI-82: Determination of screw compression force

EndoLab recently established an internal test procedure for compression screws, also known as Herbert Screws. The test method is applicable for all screws with different leading and trailing thread diameters. By this test, the axial compression force is measured while the screw is inserted into a bone substitute material.
