1. Osteocytes as indicators of bone quality - multiscale structure-composition characterisation of the bone-implant interface
Sammanfattning : By virtue of certain design features, bone anchored metal implants can be made to elicit a strong initial osteogenic response, i.e., the amount of bone formed. LÄS MER
2. Silicon nitride for total hip replacements
Sammanfattning : For more than 50 years total hip replacements have been a common and successful procedure to increase patient mobility and quality of life. The 10-year implant survival rate is 97.8%. LÄS MER
3. Tribological behaviour of HVAF-sprayed WC-based coatings: : Role of process variables and binder chemistry
Sammanfattning : Tungsten carbide (WC) based metallic matrix coatings sprayed using high velocity air fuel (HVAF) technique have attracted increasing attention as they show excellent tribological performance in various wear conditions. In the HVAF method, particles’ in-flight temperature and velocity can be influenced by the process variables including nozzle configuration as well as feedstock particle size range. LÄS MER
4. On cobalt-chrome frameworks in implant dentistry
Sammanfattning : Background: Cobalt-chrome (CoCr) alloys have been used in dentistry in decades but very little is known about their behavior and biological impact as framework materials in implant dentistry. Furthermore, few studies have evaluated and compared the clinical and radiological results of abutment and abutment-free implant treatment concepts. LÄS MER
5. Towards more sustainable approaches for protecting surfaces against wear
Sammanfattning : WC-Co coatings, with and without chromium additives, are widely used in the industry for severe tribological applications. However, concerns about cobalt supply and its environmental and health impacts have led industries to explore sustainable binder alternatives. LÄS MER
