11. On a novel technique for preparation and analysis of the implant surface and its interface to bone
Abstract : The ultrastructural and biomechanical properties of the bone-implant interface are important factors for implant performance. For further understanding of the osseointegration process novel tools enabling analysis of the intact interface in high resolution is needed, preferably combined with histology and biomechanical tests.

12. On titanium release from dental implants and the inflammatory response
Abstract : In dentistry, dental implants have become a standard treatment for single tooth loss and partial and total edentulism since their introduction by P-I Brånemark in the 1960s. Long-term follow-up studies have shown that dental implantation is a predictable treatment, with an overall implant survival over ninety-five percent. READ MORE

13. Towards a Chemisorption Model for Transition-Metal Nitrides and Carbides from Density-Functional Theory: A TiN and TiC Case Study
Abstract : Since the 1960's, a number of models for chemisorption on metals has beenpresented, most notably the Anderson-Grimley-Newns model for metals and thed-band model of Hammer and Nørskov for transition metals. The intention of this thesis is to explore the adsorption on transition-metal nitrides andcarbides, technologically interesting materials (in, e. READ MORE

14. Infections associated with percutaneous osseointegrated titanium implants for limb prostheses
Abstract : Femoral amputation is a devastating event. Percutaneous, bone anchored prosthetic systems reduce problems associated with socket suspended prostheses, but the design is inherently vulnerable to infection. READ MORE

15. Insulin-coated titanium implants - a potential therapy for local bone regeneration
Abstract : Background: Insulin is a hormone that regulates glucose metabolism, however, it is also important for bone formation. The anabolic effect of insulin on bone could open up alternative therapies when it comes to local bone regeneration. However, this requires a method for local administration of insulin. READ MORE
