  1. 16. Developmental disturbances of cementum induced by 1-hydroxyethylidene-1, 1-bisphosphonate (HEBP) : experimental studies on rats

    Författare :Idil Alatli Burt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :dental cementum; dentin; rat molar; bisphosphonate; mineralization; scanningelectron microscopy; immunohistochemistry; epithelial root sheath.Repro Print AB; Stockholm 1996;

    Sammanfattning : By studying the mechanism(s) behind experimentally induced developmental disturbances of a tissue, it may be possible to gain information about its normal development. Cementum seems to be the least understood of the dental tissues, and there are very few studies in which its development has been experimentally altered. LÄS MER

    Sammanfattning : In five autopsy specimen studies human temporomandibular joints were investigated by conventional tomography, macroscopy, and microscopy for degenerative changes, in particular erosive hard-tissue changes.In the microscopical evaluation special attention was paid to the calcified cartilage.

  4. 18. On osseointegration in response to controlled surface nanotopography

    Författare :Dimitrios Karazisis; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in vivo; nanotopography; osseointegration; topography;

    Sammanfattning : Knowledge about the biological responses provoked by the surface modification of titanium implants on the nanoscale is still in its infancy. Although in vitro studies claim superior effects considering higher adhesion and proliferation of osteoblasts in the short term and even differentiation towards the osteogenic cell lineage in the long term, these responses do not necessarily reflect the actual outcome in the complex in vivo environment.

  5. 19. Clinical and experimental studies of bone substitutes and dental implants in compromised bone sites

    Författare :Amela Trbakovic; Andreas Thor; Patricia Hedenqvist; Christer Dahlin; Uppsala universitet; []
    Nyckelord :clinical follow-up; calcium phosphates; rabbit model; sinus lift; radius model; in vivo; bisphosphonates; narrow diameter implants; dental implants; Oral and Maxillofacial Surgery; Käkkirurgi;

    Sammanfattning : Background: With an ageing population, an increase of more challenging implant treatments is expected. In this thesis, we evaluate the outcome of two faster implant protocols, in patients with compromised alveolar bone. LÄS MER

  7. 20. Titanium Oxide and Bone Anchorage: Role of the Complement System, and Delivery of Osteoporosis Drugs from Mesoporous TiO2

    Författare :Necati Harmankaya; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titania; complement; photocatalysis; ovariectomy; alendronate; raloxifene;

    Sammanfattning : The clinical success of bone implants of titanium (Ti) is largely ascribed to the biological performance and the physicochemical properties of the outermost titanium(IV)dioxide (TiO2) layer. Several advancements have been done on TiO2 in order to optimize its healing and anchorage to bone, and there is a need for further understanding and control of the molecular reactions preceding long-term osseointegration.
