The stiffness of CoCrMo-implants is higher than that of stainless steel and titanium and new production methods result in very fine-grained alloy compositions [ 15 ].
Mechanical properties of the ingrowth and stability of endosseous implants are commonly investigated through in-vitro pullout tests, where the primary output is the macroscopic load-displacement response Iijima et al.
High x-ray energy [e.
A saline steam was inserted in the loading chamber before each test to keep the samples hydrated. Data Sheet S3.
However, the high energy needs to be combined with a long exposure time to ensure enough contrast, e. This could suggest that bone started to fail at a distance away from the screw while the interface was still intact, and that the cracks then propagated toward the screw-bone interface until failure, delaying the rupture of the interface.
Stainless steel L has proven to be a good material for metal implants and was often used in trauma surgery [ 16 ]. Each screw type was introduced into the 9 positions of each pelvis.
Biomaterial strategies for engineering implants for enhanced osseointegration and bone repair. Then surfaces were then treated as follows.
Therefore, different alloys are on the market, which improve the properties of pure titanium [ 25 ]. An extensive range of image processing steps including mean, median, Gaussian, band pass, edge detection techniques, screw removal in sinograms were applied to the images to reduce the artifacts, unfortunately with limited success.
