Modelling of bone surrounding implants
 3D-model of bone and implant with boundary conditions
| For structural analysis of implants it is not only important to know the strength of the implant but also the interactions with the surrounding bone structure. | Bone is characterised by it’s inhomogenity and direction dependent elasticity and strength properties which vary with the place and the specific loading conditions.

Moreover, the bone is a living and highly sensitive material which is able to remodel itself in consequence of changing loading conditions over time. If for instance the physiological stress distribution is disturbed by an implanted intramedullary nail, the structure and density of bone can change considerably over time as a result of excessive or too low stresses in the direct environment of the implant. |

 Elastic strain on cross section of bone | The knowledge of these processes in dependence on the design of the implants is of high importance. Using the Finite Element (FE) method, ASD is able to consider the three - dimensional bone structure in the direct implant environment in a simplified manner. Thus, not only the structural properties of the implant but also their effects on the adjacent structure can be investigated to minimise possible complications. | |||
