  1. 1. Surface roughness and ion release properties of a bioactive restorative material Predicta Bioactive Bulk-fill

    Master-uppsats, Umeå universitet/Institutionen för odontologi

    Författare :Joel Berglund; Oscar Adell; [2022]
    Nyckelord :Predicta Bioactive Bulk-Fill; Surface roughness; ion release.;

    Sammanfattning : Background: Dental filling materials are used on a regular basis by dentists. Commonly used filling materials on the current market are resin composites and glass ionomers cements. However, new materials continue to be presented on the market with claimed improved physical and chemical properties, among them Predicta Bioactive Bulk. LÄS MER

  3. 2. Bioactivity testing of dental materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Alexander Eriksson; [2019]
    Nyckelord :Bioactivity; bioactive glass; soaking experiment;

    Sammanfattning :  Ever since Hench et al. first discovered bioactive glass in 1969, extensive interest was created because of the materials ability to chemically bond with living tissue. In this project the bioactivity of three different compositions of the bioactive glass Na2O-CaO-SiO2 have been studied. LÄS MER

  4. 3. Biodegradable Composites : Processing of thermoplastic polymers for medical applications.

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Behzad Damadzadeh; Hamideh Jabari; [2009]
    Nyckelord :poly lactic acid; poly glycolic acid; microcompounder; in-vitro degradation; biomedical application; hydroxy appetite hap ; tricalcium phosphate tcp ; bioactive glass bag ; bioceramic; medical composite; differential scanning calorimetry dsc ; inherent viscosity; termogravimetric analysis tga ; scanning electron microscopy sem ; biodegradable composite;

    Sammanfattning : Despite the recent development in PLA and PLGA based medical devices, there are still needs to further improve the mechanical performance of bioresorbable medical implants and their bioactivity. This is normally done by optimizing the filler compositions in selected groups ofbiodegradable polymer matrices. LÄS MER
