If not absolutely necessary, implants should remain in the human body for a defined period of time and degenerate depending on time and/or load. Within the application phase, the implant should take over the entire support function and then successively transfer this to the surrounding tissue and bone. Therefore the implant should lose strength and stiffness and thus absorb less load compared to the reconnected bone structure. This has the advantage that a targeted growth-promoting load stimulation of the bone can take place and, in addition to stress shielding, explantation can be avoided. In previous approaches, it has been shown that a suitable structure and geometry selection can influencing the specific properties as well as the lifetime of additively manufactured structures by fracture mechanics phenomena.
Thus different lifetime influencing measures are investigated, both eperimentally and numerically, by using the example of angle-stable plate osteosynthesis made of Ti-6Al-4V.
