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

    Author : Anders Palmquist; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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.

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

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

    Abstract : 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. READ MORE

  5. 3. Study of Non-metallic Inclusion in Alloy 825

    Author : Hans Kellner; Andrey Karasev; Pär Jönsson; Guozhu Ye; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 825; FeTi70R alloy; non-metallic inclusions; inclusion distribution; clusters; electromagnetic and gas stirring; ladle treatment; electrolytic extraction; stirring directions; Alloy 825; FeTi70R legering; icke-metalliska inneslutningar; inneslutnings fördelning; kluster; elektromagnetisk och gas omrörning; skänkugnsbehandling; elektrolytisk extraktion; omrörningshåll; Metallurgical process science; Metallurgisk processvetenskap; Steel Forming and Surface Engineering;

    Abstract : 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. READ MORE

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

    Author : Eva-Lis Odenberger; Roger Reed; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot sheet metal forming; Titanium; FE simulation; Validation; Springback; HCP; Varmforming; Titan; FE simulering; Validering; Återfjädring; HCP; Hållfasthetslära; Solid Mechanics;

    Abstract : 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. READ MORE

  7. 5. Soft tissue integration to dental implants

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

    Abstract : 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. READ MORE
