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

    Författare :Anders Palmquist; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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.

  2. 2. Development of titanium-copper alloys for dental applications

    Författare :Lee Fowler; Caroline Öhman-Mägi; Håkan Engqvist; Susanne Norgren; Eduard Hryha; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

    Sammanfattning : It is well known that inclusions affect the properties of steels and alloys. Therefore, it is important to understand what type of inclusions that exist and how they behave and especially with a focus on large size inclusions. LÄS MER

  4. 4. Concepts for hot sheet metal forming of titanium alloys

    Författare :Eva-Lis Odenberger; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot sheet metal forming; Titanium; FE simulation; Validation; Springback; HCP; Engineering mechanics - Solid mechanics; Varmforming; Titan; FE simulering; Validering; Återfjädring; HCP; Teknisk mekanik - Fastkroppsmekanik; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. LÄS MER

  5. 5. Soft tissue integration to dental implants

    Författare :Maria Welander; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; connective tissue; dental implants; epithelium; gold alloy; histology; peri-implant mucosa; subcrestal placement; titanium; zirconia;

    Sammanfattning : Soft tissue integration is a prerequisite for implant success. The role of the soft tissue barrier at implants is to provide an effective seal that protects the underlying bone and prevents access for microorganisms and their products. LÄS MER
