  1. 11. On tissue reactions to dentin as a bone substitute material

    Författare :Payam Farzad; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grafted dentin; tissue reaction; bone blocks; dental implants; experimental study;

    Sammanfattning : Background Reconstruction of the jaws due to resorption of the alveolar crest may require bone augmentation prior to installation of endosseous implants. Active research on new bone graft materials with bone regeneration ability equivalent to autogenous bone but without the limitations of allogenic, xenogenic and synthetic bone are constantly ongoing.

  3. 12. Effects of silicon on bone. Clinical observations and experimental cell studies

    Författare :Catarina Magnusson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; silicon; osteoclast; pregnancy; lactation; bone metabolism; bone regeneration;

    Sammanfattning : Bone health has a major impact on life quality. In Sweden, osteoporosis is a highly prevalent skeletal disease that primarily affects the elderly, causing fragility fractures and pain. LÄS MER

    Sammanfattning : Basic (apatite-based) calcium phosphate cements (CPCs), and acidic (brushite and monetite-based) CPCs are used as bone replacement materials because of their bioactivity, mouldability and ability to harden in place. However, their application is limited by their inherent brittleness and difficulties related to their handling. LÄS MER

  5. 14. Biomaterials as carriers for bone active molecules-An approach to create off-the-shelf bone substitutes

    Författare :Deepak Raina; Lund Ortopedi; []

    Sammanfattning : Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. LÄS MER

  7. 15. Mechanical analyses of trabecular bone and its interaction with implants
