  1. 16. On possibly bioactive CP titanium implant surfaces

    Författare :Anna Göransson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium implants; surface modification; bioactivity; bone tissue; cell culture;

    Sammanfattning : Background Osseointegrated titanium implants are routinely used in clinical dentistry. Although the overallclinical results are good, there are situations when an improved implant healing is desirable, for instance incompromised bone or in order to decrease healing time. LÄS MER

  3. 17. Development of titanium-copper alloys for dental applications

    Författare :Lee Fowler; Caroline Öhman-Mägi; Håkan Engqvist; Susanne Norgren; Eduard Hryha; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium; copper; antibacterial; Ti2Cu; biomaterials; Staphylococcus epidermidis; MC3T3 cells;

    Sammanfattning : Titanium alloys find wide application in the medical implants industry, which includes areas of orthopaedic and dental implants. The reason for the popularity of the material is high mechanical strength, low density, and reported growth of bone onto the material, as well as corrosion resistance. LÄS MER

  4. 18. 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

  5. 19. Biomaterial Components Prepared by Titanium Powder Technology

    Författare :Mikael Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dental; coping; biomaterial; titanium-hydroxyapatite composite; crown; cold isostatic pressing; deformation; titanium powder; high velocity compaction; powder metallurgy;

    Sammanfattning : The main objectives of this work were twofold: First, to determine if a pressed-powder method could be used to fabricate titanium dental copings, and to line out what problems or benefits this new method would have. Second, to test if high velocity compaction of titanium powder could be used to form biomaterial components such as copings or dental implants. LÄS MER

  7. 20. Preparation and Characterization of Glow Disharge Modifies Titanium Surfaces

    Författare :Björn-Owe Aronsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Titanium; surface modification; surface properties; plasma techniques; oxidation; surface spectroscopy; TiO2; biomaterials;

    Sammanfattning : The main theme of the present thesis is controlled preparation and characterization of oxidized titanium surfaces. Such surfaces are of general technological interest. LÄS MER
