  2. 21. On Clinical and Mechanical Aspects in Implant Supported Screw Retained Multi-unit CAD-CAM Metal Framework

    Author : Marco Toia; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Conventionally casted frameworks have been considered the preferredsolutions for complete and partial restorations since the beginningof implantology. However, following technological development, thecomputer aided design/computer aided manufacturing (CAD-CAM)with milling the frameworks has been introduced as an alternativeoption with the potential of minimising inaccuracies, reducing theoperator dependence and offering a homogeneous structure with highmechanical properties.

  4. 22. On the biological behavior of barrier membranes: implications for Guided Bone Regeneration. Clinical and Experimental studies

    Author : Alberto Turri; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Guided Bone Regeneration; Membranes;

    Abstract : There is a continuous development of bone augmentation solutions to meet the rising demand for effective dental implant rehabilitations. One of the most used techniques is Guided Bone Regeneration (GBR). READ MORE

  5. 23. Gene expression during hard tissue formation

    Author : Catharina Ellerström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : bone; dentin; mRNA; fibrillar collagens; osteonectin; fibronectin; development; rat;

    Abstract : The purpose of this thesis was to study the formation of the extracellular matrix (ECM) of bone and dentin during development. Molecular techniques, such as in situ hybridization and RT-PCR, were used to investigate the occurrence of specific gene products in formative cells. READ MORE

  6. 24. Cone Beam Computed Tomography in Evaluations of Some Side Effects of Orthodontic Treatment

    Author : Henrik Lund; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cone beam computed tomography; orthodontics; adolescents; root resorption; marginal bone height;

    Abstract : In the late 1990s a new imaging modality, Cone Beam CT (CBCT) that enables high quality three-dimensional imaging at lower doses than Computed Tomography (CT), was introduced in dento-maxillofacial imaging. In 2005 the Swedish Council on Health Technology Assessment (SBU), in a review of scientific articles on Malocclusions and Orthodontic Treatment in a Health Perspective, found low or contradictive evidence for an association between orthodontic treatment and risks for negative side effects.

  7. 25. On Bone Regeneration in Porous Bioceramics - Studies in humans and rabbits using free form fabricated scaffolds

    Author : Johan Malmström; Göteborgs universitet; []
    Keywords : bone regeneration; hydroxyapatite; zirconia; macroporosity; microporosity; free form fabrication; focused ion beam; scanning electron microscopy; transmission electron microscopy; rabbit; human;

    Abstract : The objective of the present thesis was to evaluate the effect of material chemistry and macroand micro-porosity on bone regeneration in association with synthetic, porous ceramic materials. Ceramic scaffolds were designed and manufactured for experimental and human studies using free form fabrication (FFF), a technique which produces the object layer by layer using data from CAD files.
