  1. 6. Development of polymer based composite filaments for 3D printing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Elin Åkerlund; [2019]
    Nyckelord :3D-printing; fused deposition modeling FDM ; composite filaments; biocompatible materials; biodegradability; medical applications; scaffold materials; poly lactic acid PLA ; polycaprolactone PCL ; hydroxyapatite HA ; mechanical properties; thermal stability; chemical composition; morphological characterization; accelerated degradation study; polymer degradation behavior;

    Sammanfattning : The relatively new and still growing field of 3D-printing has opened up the possibilities to manufacture patient-specific medical devices with high geometrical accuracy in a precise and quick manner. Additionally, biocompatible materials are a demand for all medical applications while biodegradability is of importance when developing scaffolds for tissue growth for instance. LÄS MER

  3. 7. Bioactivity testing of dental materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Alexander Eriksson; [2019]
    Nyckelord :Bioactivity; bioactive glass; soaking experiment;

    Sammanfattning :  Ever since Hench et al. first discovered bioactive glass in 1969, extensive interest was created because of the materials ability to chemically bond with living tissue. In this project the bioactivity of three different compositions of the bioactive glass Na2O-CaO-SiO2 have been studied. LÄS MER

  4. 8. Biomechanical Analysis of Implant plates for Mandibular Condyle fractures

    Master-uppsats,

    Författare :Viswambik Rohit Kumar Dhurvasula; [2019]
    Nyckelord :Finite Element Analysis; Hydroxyapatite; Poly-L-lactic acid; stress shielding; Maxillofacial surgery.;

    Sammanfattning : In the field of maxillofacial surgery, the treatment for the recovery of the fracture at condyle region of the mandible has been carried out using Bio-metals such as Titanium, Cobalt, Stainless-Steel because they were considered the standard materials for Implant plate devices for fracture fixation. Using these materials have led to undesired disturbances where the patient must undergo secondary surgery after recovery leading to exposure of the fracture site to the surrounding, metal-ion release into the human system, stress-shielding and interruption during imaging i.

  7. 10. Synthetic bone grafts for treatment of femoral head necrosis

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Sebastian Borg; [2017]
    Nyckelord :;

    Sammanfattning : Necrosis of the femoral head is a relatively common medical condition that radically decrease the quality of life for the patient. Left untreated it could lead to destruction of the hip joint. A common treatment is using bone autografts, also called bone chips. LÄS MER
