1. 1. Bone Healing after implantation of bone substitute materials. Experimental studies in estrogen deficiency

   Författare :Sven Öberg; Jan Rosenquist; Ulf Lekholm; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Bone grafts; hydroxyapatite; estrogen deficiency; demineralised bone; bone formation; AAA bone; bone defect; titanium implants; resonance frequency analysis.; Kirurgi; Surgery; Kirurgi; kirurgi; Surgery;

   Sammanfattning : Bone formation and bone healing were studied in the mandible, tibia and skull bones in adult, healthy and estrogen deficient rabbits implanted with different bone substitutes.In the first study an evaluation of the differences in bone regeneration in and around solid (Alveograf *) and porous hydroxyapatite (Interpore 200*) was undertaken.

3. 2. Molecular and structural patterns of guided bone regeneration (GBR). Experimental studies on the role of GBR membrane and bone substitute materials

   Författare :Ibrahim Elgali; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regenerative medicine; biomaterials; bone substitute; calcium phosphate; guided bone regeneration; membrane; strontium; bone defect; bone remodeling; inflammation; cytokines; chemokines; growth factors; gene expression; histomorphometry; in vivo;

   Sammanfattning : The mechanisms of guided bone regeneration (GBR) and bone healing with calcium phosphate (CaP) bone substitutes are not fully understood. The major aim of this thesis was to determine the relationship between the bone formation in bone defects and the cellular distribution and activities in association with CaP materials and/or with GBR membrane.

4. 3. An injectable biphasic bone substitute in sinus augmentation

   Författare :Anna Truedsson; Malmö högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dentala implantat; Dental Implants; Bone transplantation; Bone substitutes;

   Sammanfattning : This thesis concerns a new synthetic, injectable bone substitute, Cerament™, primarily developed for treatment of vertebral fractures. The purpose of the thesis was to investigate the properties of the newbone substitute, that is, whether it can contribute to the generation of new bone formation needed for placement of future dental implants.

5. 4. Injectable Calcium Phosphate Bone Substitute In Distal Radial Fractures

   Författare :Philippe Kopylov; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Norian SRS; Bone substitute; radius fracture; injectable; calcium phosphate; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : Fractures of the distal end of the radius are common and occur in many different forms. The long-term results after conservative treatment of fracture of the distal end of the radius in younger adults with special reference to degenerative changes and function are investigated in 76 patients (Paper I).

7. 5. Biological interface of bone graft substitute materials : experimental studies on interactions between biomaterials and bone cells

   Författare :Zivko Mladenovic; Maria Ransjö; Joost D de Brujin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Bone graft substitute materials are becoming more common as alternative therapy strategies when bone defects in patients need to be treated. The interaction between bone cells and biomaterials occur at the surface of the materials. A great deal is known about the importance of surface topography and physic-chemical properties of biomaterials. LÄS MER
