Advanced Implant Solutions

The development and application of new materials and process technologies enables targeted improvement of material properties and the design and production of innovative implants. In this context, the AIS team collaborates closely with leading national and international research institutions and companies. Our research and development activities include both permanent and biodegradable metal-based implants.

Permanent implants require new materials with excellent biocompatibility and tailored properties in terms of strength, hardness, workability, longer service life and high patient comfort.
Novel biodegradable metallic materials for implants must combine highest biocompatibility, good mechanical properties and controllable degradation rates in the body. These biomaterials are designed for use in osteosynthesis systems and in vascular environments and offer the great advantage that they are absorbed by the body once they have fulfilled their function and thus do not need to be removed surgically.

These biodegradable metallic materials feature excellent biocompatibility in vivo, but specific in vitro cytocompatibility tests according to ISO standards are lacking. The existing ISO standard tests for metal implants are primarily designed for permanent metals. The new application-oriented 3D test setups provide a clearer picture of the processes within the organism and thus enable better prediction and planning of in vivo tests.
