| Outline of Final Research Achievements |
The purpose of this study is to investigate the mechanical requirements of tissue- implant interface. The interface of spark anodized titanium- bone ingrowth likely enables a functionally graded Young’s modulus, thereby allowing reduction of stress shielding. The understanding of complex mechanical bone behavior and size-dependent properties ranging from nano- to a mesoscopic level are essential in the biomechanical optimization of implants. The requirements of regenerated tissue at the interface include high strength, fracture toughness related to ductility, and time-dependent energy dissipation and/or elastic-plastic stress distribution. Moreover, a strong relationship between strain signals and peri-implant tissue turnover could be expected, so that ideal implant biomechanics allows longevity via adaptive bone remodeling.
