  1. 1. On healing after periapical surgery and different retrograde root-filling materials. A clinical and histological study

    Författare :Dan-Åke Wälivaara; Göteborgs universitet; []
    Nyckelord :periapical surgery; ultrasonic preparation; IRM; thermoplasticized gutta-percha; Super-EBA; mineral trioxide aggregate; root-filling status; lesion size; lesion type;

    Sammanfattning : Aims: The outcome from conventional endodontic therapy does not always result in a healing of the periapical area, thus leaving a remaining lesion with or without symptoms. The primary treatment alternative is a revision of the orthograde root-filling if applicable. A second treatment alternative might be a periapical surgery procedure. LÄS MER

  3. 2. Bone tissue regeneration indento-alveolar surgery : clinical and experimental studies on biomaterials and bone graft substitutes

    Författare :Annika Sahlin-Platt; Maria Ransjö; Christer Dahlin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomaterials; bone graft substitutes; compomer; root end filling; Bio-Oss; Bioactive glass 45S5; Algipore; SEM EDAX; ICP-OES; Cryo-XPS;

    Sammanfattning : Pathological processes in the alveolar and facial bones can lead to bone loss that may not heal with complete regeneration. Biomaterials can be used to facilitate the healing process and/or as a bone substitute, but the mechanisms are not fully understood. LÄS MER

  4. 3. Computation of Thermal Development in Injection Mould Filling, based on the Distance Model

    Författare :Per-Åke Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermoplastic materials; finite element FEM ; finite difference FD ; Newton-Mysovskii theorem; Moldflow Mfl ; Cadmould Cmd ; MATHEMATICS; MATEMATIK;

    Sammanfattning : The heat transfer in the filling phase of injection moulding is studied, based on Gunnar Aronsson’s distance model for flow expansion ([Aronsson], 1996).The choice of a thermoplastic materials model is motivated by general physical properties, admitting temperature and pressure dependence.
