  1. 21. On platelet-rich plasma in reconstructive dental implant surgery

    Författare :Andreas Thor; Göteborgs universitet; []
    Nyckelord :autogenous bone graft; bone formation; coagulation; clinical study; complement; dental implant; experimental study; growth factors; platelet activation; platelet-rich plasma; sinus lift surgery; thrombogenicity;

    Sammanfattning : Abstract Background Severe athrophy of the edentulous maxilla may require augmentation before implants can be placed. Autogenous bone has been used for reconstruction in block or in particulated form. LÄS MER

  3. 22. On costochondral grafts replacing mandibular condyles in juvenile chronic arthritis. A clinical, histological and experimental study

    Författare :Börje Svensson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; juvenile chronic arthritis; temporomandibular joints; temporomandibular disorders; costochondral grafts; growth; revascularisation; microangiography; fluorochrome labelling.;

    Sammanfattning : In children with juvenile chronic arthritis (JCA), disturbances of mandibular growth and function may result in involvement of the temporomandibular joints (TMJs). The aim of this thesis was to study the stomatognathic system in JCA children and long-term effects on facial growth of treatment comprising replacement of arthritic mandibular condyles with autogenous costochondral grafts (CCGs) during growth.

  4. 23. On guided bone reformation in the maxillary sinus to enable placement and integration of endosseous implants. Clinical and experimental studies

    Författare :Giovanni Cricchio; Stefan Lundgren; Lars Sennerby; Gerry Raghoebar; Umeå universitet; []
    Nyckelord :bone grafting; donor morbidity; iliac crest; dental implants; membrane elevation; maxillary sinus floor elevation;

    Sammanfattning : Dental caries and periodontal disease are the major causes for tooth loss. While dental caries commonly involve the posterior teeth in both jaws, the teeth most commonly lost due to periodontal problems are the first and second molars in the maxilla. As a consequence, the upper posterior jaw is frequently edentulous. LÄS MER

  5. 24. On guided bone regeneration using ceramic membranes

    Författare :Jonas Anderud; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Regeneration of bone in the oral and maxillofacial region can beachieved with different techniques such as autologous bone grafts,bone substitutes and guided bone regeneration. Guided boneregeneration is defined as creating a space between the bone and itssurrounding tissues, using a barrier that allows new bone to migrateinto the space while preventing other cell types from interfering.

  7. 25. On magnesium-containing implants for bone applications

    Författare :Silvia Galli; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The biomedical technologies for bone application are employed in millions of patients every year to restore function and aesthetics following trauma, diseases and congenital deformities. They achieved significant advancements in the last decades and have resulted in the development of implants that function for long periods of time. LÄS MER
