  1. 21. Influence of a dental ceramic and a calcium aluminate cement on dental biofilm formation and gingival inflammatory response

    Författare :Katarina Konradsson; Jan van Dijken; Rolf Claesson; Lars Gahnberg; Umeå universitet; []
    Nyckelord :cements; ceramics; cytotoxicity; dental biofilm; gingivitis; interleukin-1; oral hygiene; resin composite;

    Sammanfattning : Dental restorative materials interact with their surrounding oral environment. Interaction factors can be release of toxic components and/or effects on biofilm formation and gingiva. In the end of the nineties, a calcium aluminate cement (CAC) was manufactured as a “bioceramic” alternative to resin composite. LÄS MER

  3. 22. On platelet-rich plasma in reconstructive dental implant surgery

    Författare :Andreas Thor; Göteborgs universitet; []
    Nyckelord :autogenous bone graft; bone formation; coagulation; clinical study; complement; dental implant; experimental study; growth factors; platelet activation; platelet-rich plasma; sinus lift surgery; thrombogenicity;

    Sammanfattning : Abstract Background Severe athrophy of the edentulous maxilla may require augmentation before implants can be placed. Autogenous bone has been used for reconstruction in block or in particulated form. LÄS MER

  4. 23. Health implications of dental amalgam

    Författare :Aron Naimi-Akbar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Dental amalgam is one of the most widely used, but also the most controversial of dental restorative materials. Since its introduction during the first half of the 19th century, concerns have been raised about health hazards related to the toxicity of a major component of amalgam, mercury. LÄS MER

  5. 24. In vivo and in vitro studies of polyetheretherketone: bone formation, inflammatory response and biofilm formation

    Författare :Sargon Barkarmo; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PEEK; polyetheretherketone; hydroxyapatite; nanotopography; osseointegration; cytokines; biofilms; biomaterials; dental materials; titanium; nanocoated;

    Sammanfattning : In prosthetic dentistry, restorative materials are used to replace missing teeth and tissues, so as to maintain oral functionalities and comfort for the patient. Depending on the clinical problem, metals, ceramics or polymers, are used both in dentistry and orthopedics. LÄS MER

  7. 25. Calcium-Aluminate as Biomaterial : Synthesis, Design and Evaluation

    Författare :Jesper Lööf; Håkan Engqvist; Sture Hogmark; Elis Carlström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium-aluminate; Biomaterial; Dental materials; Vertebroplasty; Chemically Bonded Ceramics; Synthesis; Biomaterials; Biomaterial;

    Sammanfattning : In this thesis different aspects of calcium-aluminate (CA) as biomaterial are presented. Calcium aluminate is a chemically bonded ceramic with inherent properties making it suitable for use as biomaterial in some applications. LÄS MER
