  1. 16. On the tissue response to hafnium, titanium and thin calcium phosphate coatings

    Författare :Sham Mohammadi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hafnium; titanium; calcium phosphates; hydroxyapatite; implants; bone; soft tissue; histomorphometry;

    Sammanfattning : Background: Titanium (Ti) is the gold standard material for load-bearing implants. Although high success rates have been reported for Ti implants, failures do occur. Alternative materials/surface modifications might further improve the performances of Ti implants, particularly in situations with non-optimal local tissue conditions. LÄS MER

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

    Författare :Michael Pujari-Palmer; Håkan Engqvist; Marjam Karlsson Ott; Christele Combes; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 19. Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements

    Författare :Simon Jegou Saint-Jean; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materiallära; materialteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Material technology; isothermal calorimetry.; Rietveld method; X-ray diffraction; silicon; strontium; Portland cement; calcium phosphate cement; chlorellestadite; Solid solutions; apatite;

    Sammanfattning : The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. LÄS MER

  7. 20. On healing of titanium implants in biphasic calcium phosphate

    Författare :Christer Lindgren; Mats Hallman; Per Aspenberg; Lars Andersson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background: Previously, autogenous bone was considered the gold standard for grafting procedures in implant surgery. Today, the use of bone graft substitutes is an alternative for sinus lift procedures. Nevertheless, only a few bone substitutes are well documented and can be recommended as an alternative to autogenous bone grafts. LÄS MER
