6. Bioactive Coatings and Antibacterial Approaches for Titanium Medical Implants
Sammanfattning : The aim of this thesis was to characterize and manufacture coatings and surfaces with antibacterial properties and retained or enhanced bioactivity and biocompatibility. The aim was also to study the optimal composition and parameters of mixtures for debridement of bacterial biofilms on titanium surfaces. LÄS MER
7. 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
8. Tissue reactions to biomaterials
Sammanfattning : The biological response to different implanted biomaterials vary. The relative importance of factors in the material and host for this variation are at present incompletely known. LÄS MER
9. Methods for evaluation of early bone healing at titanium implants
Sammanfattning : Titanium has for a long time been the implant material of choice when in need for abilities as strength, biocompatibility and stability. Although numbers of studies have been made, little is known about the early events in implant healing. The primary aim in this thesis was to develop methods for evaluating bone healing around implants. LÄS MER
10. Improved titanium and steel implants : Studies on bisphosphonate, strontium and surface treatments
Sammanfattning : Purpose: The general aim of this thesis was to increase the understanding of biomaterial surface modifications and local delivery of osteoporosis drugs for bone integration. We therefore (i) characterised and investigated model surface coatings for controlled drug delivery in a rat tibia screw model (ii) elucidated the effect of surface treatment for activation of complement system in vitro.
