  1. 1. Novel Insights into Inflammatory Disturbed Bone Remodelling

    Författare :Elin Kindstedt; Pernilla Lundberg; Östen Ljunggren; Umeå universitet; []

    Sammanfattning : Bone is a dynamic tissue that is continuously remodelled, a process that requires equal amounts of osteoclastic bone resorption and osteoblastic bone formation. Inflammation may disturb the equilibrium and result in local and/or systemic bone loss. Negative bone mass balance occurs in several chronic inflammatory diseases, e.g. LÄS MER

  3. 2. On tissue reactions to and resorption of bone substitutes

    Författare :Arne Mordenfeld; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone graft; bone substitutes; sinus floor augmentation; lateral ridge augmentation;

    Sammanfattning : Background: The increasing need for bone grafting procedures inimplant dentistry and the introduction of a variety of bone substitutesrequire a deeper understanding of the biological response and shortandlong-term behaviour of these materials to choose the adequategraft and surgical procedure for the intended clinical application.Aims: The overall aim was to clinically and histologically studythe short- and long-term tissue reactions to and resorption of bonesubstitutes after bone augmentation.

  4. 3. The effect of tobacco exposure on bone healing and the osseointegrationof dental implants

    Författare :Shariel Sayardoust; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; crevicular fluid; dental implants; gene expression; human; implant surfaces; implant survival; marginal bone loss; osseointegration; pain; periodontitis; resonance frequently analysis; smoking; titanium;

    Sammanfattning : Background: The mechanisms behind the impact of smoking on osseointegration are not fully understood. Aim: To correlate the clinical and molecular aspects of osseointegration in smokers compared with non-smokers. LÄS MER

  5. 4. 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

  7. 5. On minimally invasive approaches to sinus lift procedures

    Författare :Lars-Åke Johansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autogenous bone graft; bone formation; clinical study; cone beam computed tomography; dental implants; ; flapless surgery; hydroxyapatite; osteotome technique; partially dentate maxillae; sinus lift surgery;

    Sammanfattning : Abstract Aims: The overall aim of the present thesis was to evaluate implant survival and bone regeneration after minimally invasive sinus lift procedures. Material and methods: In study I, 61 patients were prospectively evaluated 12 to 60 months after two different methods of locally bone harvesting methods adjacent to the maxillary sinus lift procedure.
