  1. 1. On a novel technique for preparation and analysis of the implant surface and its interface to bone

    Författare :Anders Palmquist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Focused Ion Beam FIB ; Transmission electron microscopy TEM ; Scanning electron microscopy SEM ; osseointegration; rabbit; human; titanium; titanium alloy; surface analysis; bone-implant interface analysis; ultrastucture; surface modification; laser;

    Sammanfattning : The ultrastructural and biomechanical properties of the bone-implant interface are important factors for implant performance. For further understanding of the osseointegration process novel tools enabling analysis of the intact interface in high resolution is needed, preferably combined with histology and biomechanical tests.

  3. 2. 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

  4. 3. High Performance Manufacturing of Advanced Thin Plates ─ Forming of Titanium and Stainless Steel Materials

    Författare :Per Gabrielson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High performance manufacturing; test tools; sheet-metal forming; stainless steel; commercially pure titanium; process optimization; forming simulation; finite element analyses; acoustic emission; production performance analysis; cost models; manufacturing costs; sustainable production;

    Sammanfattning : The manufacturing industry represents a highly important sector of the Swedish economy. The increasing demands placed on the quality and performance of products that are manufactured places increasing demands on the manufacturing processes involved. LÄS MER

  5. 4. 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

  7. 5. On cobalt-chrome frameworks in implant dentistry

    Författare :Lars Hjalmarsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cobalt-chrome; titanium; implants; misfit; corrosion; viability; abutment-free;

    Sammanfattning : Background: Cobalt-chrome (CoCr) alloys have been used in dentistry in decades but very little is known about their behavior and biological impact as framework materials in implant dentistry. Furthermore, few studies have evaluated and compared the clinical and radiological results of abutment and abutment-free implant treatment concepts. LÄS MER
