  1. 11. Haptic Milling Simulation in Six Degrees-of-Freedom : With Application to Surgery in Stiff Tissue

    Författare :Magnus G. Eriksson; Jan Wikander; Dwight Meglan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surgical simulation; Virtual reality; Haptic feedback; Surgical training; Medical simulators; 3D visualization; Six degrees-of-freedom; Bone milling;

    Sammanfattning : The research presented in this thesis describes a substantial part of the design of a prototypical surgical training simulator. The results are intended to be applied in future simulators used to educate and train surgeons for bone milling operations. LÄS MER

  3. 12. On the bone response to different implant textures. A 3D analysis of roughness, wavelength and surface pattern of experimental implants

    Författare :Carin Hallgren Höstner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surface modification; surface texture; roughness; surface evaluation; in vivo studies.;

    Sammanfattning : PurposeThe purpose of the present thesis was to investigate the bone response to different isotropic, anisotropic and organised surface patterns.Material and methodsImplant surfaces have been modified with different techniques (abrasive blasting, turning, milling, photolithography or laser ablation).

  4. 13. On hydroxyapatite modified peek implants for bone applications

    Författare :Pär Johansson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental Implants; Dentala implantat;

    Sammanfattning : People are living longer today than ever before, and the number of older adults will increase exponentially over the next coming years. However, that does not necessarily mean that they are living healthier. LÄS MER

  5. 14. An injectable biphasic bone substitute in sinus augmentation

    Författare :Anna Truedsson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dentala implantat; Dental Implants; Bone transplantation; Bone substitutes;

    Sammanfattning : This thesis concerns a new synthetic, injectable bone substitute, Cerament™, primarily developed for treatment of vertebral fractures. The purpose of the thesis was to investigate the properties of the newbone substitute, that is, whether it can contribute to the generation of new bone formation needed for placement of future dental implants.

  7. 15. On growth factors and titanium implant integration in bone

    Författare :Victoria Franke Stenport; Göteborgs universitet; []
    Nyckelord :growth factors; signal peptides; titanium implants; osseointegration; in vivo studies;

    Sammanfattning : PurposeThe purpose of the present thesis was to investigate the bone tissue response around titanium implants with one growth factor stimulating hormone and a few different growth factor substances.Material and methodsIn four studies (study I to IV) a rabbit model were used and the growth factors i.e. LÄS MER
