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

    University dissertation from Lund University, Faculty of Medicine

    Author : Deepak Raina; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018]

    Abstract : 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. READ MORE

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

    University dissertation from Umeå universitet

    Author : Sven Öberg; Umeå universitet.; [2003]
    Keywords : 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; MEDICINE Surgery; MEDICIN Kirurgi; kirurgi; Surgery;

    Abstract : 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. 3. Human embryonic stem cells for bone engineering applications

    University dissertation from Umeå universitet

    Author : Giuseppe Maria de Peppo; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human skeleton; bone; bone defects; bone regeneration; regenerative medicine; tissue engineering; biomaterials; scaffold; biocoral; titanium; osseointegration bioreactor; human stem cells; embryonic stem cells; mesenchymal stem cells; embryonic-derived progenitors; osteogenic differentiation; mineralization; immune response; in vitro; in vivo;

    Abstract : The human skeleton represents the supporting structure of the organism and accounts for about 20 percent of the total body mass. Despite its intrinsic capacity to regenerate and self-repair, this ability is limited and repair therapies are needed in a large number of clinical cases. READ MORE

  4. 4. On tissue reactions to and resorption of bone substitutes

    University dissertation from Faculty of Odontology, Malmö University

    Author : Arne Mordenfeld; Malmö University.; [2013]
    Keywords : ODONTOLOGY; ODONTOLOGI; Medicine; bone graft; bone substitutes; sinus floor augmentation; lateral ridge augmentation;

    Abstract : Background: The increasing need for bone grafting procedures in implant dentistry and the introduction of a variety of bone substitutes require a deeper understanding of the biological response and shortand long-term behaviour of these materials to choose the adequate graft and surgical procedure for the intended clinical application. Aims: The overall aim was to clinically and histologically study the short- and long-term tissue reactions to and resorption of bone substitutes after bone augmentation. READ MORE

  5. 5. Bone tissue regeneration indento-alveolar surgery clinical and experimental studies on biomaterials and bone graft substitutes

    University dissertation from Umeå : Umeå universitet

    Author : Annika Sahlin-Platt; Umeå universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomaterials; bone graft substitutes; compomer; root end filling; Bio-Oss; Bioactive glass 45S5; Algipore; SEM EDAX; ICP-OES; Cryo-XPS;

    Abstract : Pathological processes in the alveolar and facial bones can lead to bone loss that may not heal with complete regeneration. Biomaterials can be used to facilitate the healing process and/or as a bone substitute, but the mechanisms are not fully understood. READ MORE
