Material Trends in Medical Technology
Medical technology is constantly evolving, with innovative materials playing a central role. The requirements for these materials are particularly high, as they must not only be functional but also biocompatible. In this article, we examine current material trends and their significance for modern medical technology.
High-Performance Plastics in Medical Technology
Modern plastics have gained significant importance in recent years. In particular, PEEK (polyether ether ketone) has established itself as a material for various medical applications. This high-performance plastic is characterized by its excellent biocompatibility, high mechanical strength, and temperature resistance. PEEK is primarily used in implant technology, where it serves as an alternative to metallic materials.
Innovative Metal Alloys
Despite the rise of plastics, metal alloys remain an indispensable part of medical technology. Particularly in demand are:
- Titanium and titanium alloys for implants
- Cobalt-chromium alloys for orthopedic applications
- Nitinol for flexible instruments and stents
Titanium Alloys as the Gold Standard
Titanium alloys have established themselves as the standard in many medical applications due to their excellent properties. They combine high strength with low weight and offer outstanding biocompatibility. Recent developments are focused on further optimizing the surface properties to improve the integration behavior of implants.
Ceramic Materials on the Rise
Ceramic materials are gaining increasing importance in medical technology. Modern high-performance ceramics such as zirconia or alumina are characterized by their high wear resistance and chemical stability. They are mainly used in dentistry and joint prostheses. A major advantage is their natural aesthetic, which is especially appreciated in visible implants.
Coating Technologies and Surface Modifications
Surface treatment of medical products is becoming increasingly important. Modern coating technologies allow targeted improvement of the properties of implants and instruments:
- Antibacterial coatings for infection prevention
- Bioactive surfaces for improved integration
- Wear-reducing coatings for increased durability
- DLC coatings (Diamond-Like Carbon) for improved gliding properties
Biodegradable Materials
A particularly innovative trend involves biodegradable materials that dissolve in the body after fulfilling their purpose. These materials, often based on polylactic acid or magnesium alloys, are used for temporary implants or vascular stents, for example. They eliminate the need for a second surgery to remove them, thereby reducing the risk for patients.
