English abstract:
Bioresorbable materials for implants have become increasingly researched over the last
years. The bone-implant-interfaces of three different implant materials, namely a new
bioresorbable magnesium alloy, a new self-reinforced polymer implant and a conventional
titanium alloy, were tested using various methods: push-out tests, SEM and EDX analyses
as well as surface analyses based on stereoscopic 3D pictures were conducted. The fracture
energy is proposed as a very significant reference value for characterizing the mechanical
performance of a bone-implant system. By using a video-extensometer system instead of,
as is commonly done, tracking the movement of the crosshead in the push-out tests, the
accuracy of measurement could be increased.
