  2. 21. Calcium Phosphate Based Biomaterials for Bone Augmentation

    Author : Jun Luo; Cecilia Persson; Håkan Engqvist; Marc Bohner; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone substitute materials; calcium phosphate cements; apatite; brushite; monetite; setting mechanism; premixed; fibre reinforcement; composite; silk fibroin; mechanical properties; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Basic (apatite-based) calcium phosphate cements (CPCs), and acidic (brushite and monetite-based) CPCs are used as bone replacement materials because of their bioactivity, mouldability and ability to harden in place. However, their application is limited by their inherent brittleness and difficulties related to their handling. READ MORE

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

    Author : Maryam Montazerolghaem; Marjam Karlsson Ott; Håkan Engqvist; Pedro Granja; Uppsala universitet; []
    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

  5. 23. Powder Bed Fusion – Laser Beam of Mg alloy WE43 : Establishing the process – structure – properties relationship

    Author : Hanna Nilsson Åhman; Cecilia Persson; Francesco D'Elia; Pelle Mellin; Eduard Hryha; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powder bed fusion - laser beam; additive manufacturing; magnesium; WE43; microstructure; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Powder bed fusion - laser beam (PBF-LB) of Mg alloy WE43 (Mg-4wt%Y-3wt%RE-Zr) has great potential for the development of future biodegradable metal implants, as well as aerospace lightweight materials. However, the work published thus far has mainly focused on obtaining a fully dense material, and the understanding of the relationship among the PBF-LB process parameters, structure and the resulting material properties remains limited.

  6. 24. Silicon nitride for total hip replacements

    Author : Maria Pettersson; Cecilia Persson; Håkan Engqvist; Staffan Jacobson; Kenneth Holmberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SiNx; Si3N4; coatings; CoCr; Ti; alloy; tribology; wear; corrosion; dissolution; debris; hip; arthroplasty; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : For more than 50 years total hip replacements have been a common and successful procedure to increase patient mobility and quality of life. The 10-year implant survival rate is 97.8%. READ MORE

  7. 25. The biological and physical performance of high strength dicalcium phosphate cement in physiologically relevant models

    Author : Michael Pujari-Palmer; Håkan Engqvist; Marjam Karlsson Ott; Christele Combes; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomaterial; bioceramic; osteoinduction; calcium phosphate; cement; osteoblast; pyrophosphate; Rebamipide; drug delivery; screw augmentation; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : The chemical properties of calcium phosphate cements (CPCs) are very similar to the mineral phase of bone. CPCs are, consequently, very effective substrates (scaffolds) for tissue engineering; bone and stem cells attach readily, and can proliferate and differentiate to form new bone tissue. READ MORE
