  1. 1. Premixed Acidic Calcium Phosphate Cements

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Åberg; Uppsala universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monetite; brushite; bone void filler; injecatilbity; in vivo; in vitro;

    Abstract : Calcium phosphate cements are used in medicine to fill bone defects or give support to screws and plates in fracture fixation. The cements are formed via mixing a powder with water and the mixture harden through a dissolution-precipitation reaction. READ MORE

  2. 2. Influence of a dental ceramic and a calcium aluminate cement on dental biofilm formation and gingival inflammatory response

    University dissertation from Umeå : Odontologi

    Author : Katarina Konradsson; Umeå universitet.; [2007]
    Keywords : cements; ceramics; cytotoxicity; dental biofilm; gingivitis; interleukin-1; oral hygiene; resin composite;

    Abstract : Dental restorative materials interact with their surrounding oral environment. Interaction factors can be release of toxic components and/or effects on biofilm formation and gingiva. In the end of the nineties, a calcium aluminate cement (CAC) was manufactured as a “bioceramic” alternative to resin composite. READ MORE

  3. 3. Additives Increasing the Bone-Forming Potential around Calcium Phosphate Cements Statin, Strontium and Silicon

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Maryam Montazerolghaem; Uppsala universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Phosphate Cements; Osteoblast; Osteoclast; Monetite; Zebrafish; Simvastatin; Strontium; Silicon; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : More than one million people worldwide receive some kind of bone graft each year. Grafts are often needed following bone tumour removal or traumatic fractures to fill voids in the bone and to aid in the healing process. READ MORE

  4. 4. Bone-compliant cements for vertebral augmentation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Céline Robo; Uppsala universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone cement; low modulus; vertebroplasty; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Acrylic bone cement based on poly(methyl methacrylate) (PMMA) is commonly used during vertebral augmentation procedures for the treatment of osteoporosis-induced vertebral compression fractures. However, the high stiffness of the cement compared to that of the surrounding trabecular bone is presumed to facilitate the formation of new fractures shortly after surgery. READ MORE

  5. 5. Physical Properties of Acidic Calcium Phosphate Cements

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johanna Unosson; Uppsala universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The gold standard for bone replacement today, autologous bone, suffers from several disadvantages, such as the increased risk of infection due to the need for two surgeries. Degradable synthetic materials with properties similar to bone, such as calcium phosphate cements, are a promising alternative. READ MORE
