  1. 16. On dental ceramics and their fracture : a laboratory and numerical study

    Författare :Wen Kou; Göran Sjögren; Tore Dérand; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental ceramics; Finite element analysis; Fixed partial denture; Fracture; Numerical modeling; Surface treatment; Biomaterials; Biomaterial; odontologi; Odontology;

    Sammanfattning : Background Surface treatments and irregularities in the surfaces may affect the fracture of ceramics. The effects of various treatments on the surface texture of different types of ceramic cores/substructures was therefore qualitatively, quantitatively and numerically evaluated. LÄS MER

  2. 17. All-ceramic Fixed Partial Denture. Studies on aluminum oxide- and zirconium dioxide-based

    Författare :Per Vult von Steyern; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental ceramics; dental porcelain; all-ceramic; fixed partial dentures;

    Sammanfattning : Keramiska material har länge använts inom tandvården för framställning av tandersättningar. Keramer har många goda egenskaper som gör dem särskilt lämpliga att använda i munnen. LÄS MER

  3. 18. Soft tissue integration to dental implants

    Författare :Maria Welander; Göteborgs universitet; []
    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

  4. 19. Dental restorative materials from a work environmental perspective

    Författare :Emma-Christin Lönnroth; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Sammanfattning : The main occupational health hazard for dental personnel is muscle-skeletal problem, followed by symptoms caused by exposure to chemicals. Clinical dental work includes exposure to a number of products like soap, detergents, disinfectants, amalgam, mono- and oligomers, catalysts, inhibitors, solvents and adhesives. Some are chemically very active. LÄS MER

  5. 20. Managing Effects of Manufacturing Variation in Dental Medical Device Treatments - Increasing Geometrical Robustness

    Författare :Timo Kero; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mass customization and dentistry.; medical devices; virtual verification; Robust design; variation simulation; tolerance analysis;

    Sammanfattning : Today, there are many solutions for dental rehabilitation. A damaged tooth can be replaced with a dental crown, and a toothless patient can be rehabilitated with implants and a corresponding bridge set-up. Traditionally, a dental crown is manufactured by veneering porcelain to a metal surface that is obtained through the use of casting principles. LÄS MER
