1. 16. Factors affecting peri-implant tissue reactions

   Författare :Margareta Hultin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Dental implants long-term maintenance; microbiota; inflammation; periodontitis; periimplantitis smoking crevicular fluid.;

   Sammanfattning : Screw- shaped titanium implants are today routinely used m the substitution of lost teeth. In this thesis some of the biological factors related to the long-term survival and maintenance of dental implants were studied. The first arm of these studies was to evaluate the neutrophil activation around teeth and dental implants (Papers I & II). LÄS MER

3. 17. On loading protocols and abutment use in implant dentistry. Clinical studies

   Författare :Catharina Göthberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; abutment design; clinical studies; dental implants; dental prosthesis; implant-supported; gene expression; health; immediate implant loading; marginal bone loss; osseointegration; prosthodontics; risk factors; smoking; treatment outcome;

   Sammanfattning : ABSTRACT Research questions: The influence of immediate or delayed loading and the use of abutments in implant dentistry with regard to peri-implant tissues and the effect of risk parameters. Methodology: Fifty partially edentulous patients each received three Brånemark TiUnite™ implants. LÄS MER

4. 18. Development of titanium-copper alloys for dental applications

   Författare :Lee Fowler; Caroline Öhman-Mägi; Håkan Engqvist; Susanne Norgren; Eduard Hryha; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium; copper; antibacterial; Ti2Cu; biomaterials; Staphylococcus epidermidis; MC3T3 cells;

   Sammanfattning : Titanium alloys find wide application in the medical implants industry, which includes areas of orthopaedic and dental implants. The reason for the popularity of the material is high mechanical strength, low density, and reported growth of bone onto the material, as well as corrosion resistance. LÄS MER

5. 19. Toll-like receptors (TLRs) and inflammatory bone modeling

   Författare :Ali Kassem; Ulf Lerner; Pernilla Lundberg; Pedro Souza; Timothy Arnett; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toll-like receptor; osteoclast; osteoblast; bone resorption; bone formation; P. gingivalis; S. aureus; flagellin.;

   Sammanfattning : Patients with inflammatory or infectious conditions such as periodontitis, peri-implantitis, osteomyelitis, rheumatoid arthritis, septic arthritis and loosened joint prosthesis display varying severity of destruction in the adjacent bone tissue. Bone loss in inflammatory diseases is considered a consequence of cytokine induced RANKL and subsequent enhanced osteoclast formation. LÄS MER

7. 20. Studies on the relationship between periodontitis and rheumatoid arthritis

   Författare :Kaja Eriksson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Periodontitis and rheumatoid arthritis (RA) are both widespread multifactorial diseases, characterized by chronic inflammation leading to tissue and bone destruction around teeth or joints, respectively. An association between periodontitis and RA has been proposed, suggesting that the periodontal pathogen Porphyromonas gingivalis (P. LÄS MER
