  1. 1. 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.

  3. 2. On healing of titanium implants in iliac crest bone grafts

    Författare :Mats Sjöström; Stefan Lundgren; Lars Sennerby; Christian Lindqvist; Umeå universitet; []
    Nyckelord :Surgery; Edentulous atrophic maxilla; Autogenous bone graft; Endosteal implants; Microimplants; Resonance frequency analysis; Implant survival; Graft volume changes; Kirurgi; odontologi; Odontology;

    Sammanfattning : Bone grafts and titanium implants are commonly used for surgical/prosthetic rehabilitation of the atrophic edentulous maxilla. The factors which influence bone graft healing and implant integration are not sufficiently understood. LÄS MER

  4. 3. 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.

  5. 4. 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

  7. 5. 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.
