  3. 2. Nocturnal enuresis and rapid maxillary expansion : – long-term effect, prognostic variables, respiration during sleep and quality of life

    Författare :Ingrid Jönson Ring; Bazargani Farhan; Tryggve Nevéus; Agneta Markström; Maria Ransjö; Uppsala universitet; []
    Nyckelord :Rapid maxillary expansion; nocturnal enuresis; sleep disordered breathing; respiration; polygraphic sleep recording; quality of life.; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Background:The orthodontic technique rapid maxillary expansion (RME) has been reported to have a potentially curative effect on nocturnal enuresis (NE). The mechanism behind this is unknown but could possibly be due to placebo and/or effects on respiration during sleep. LÄS MER

  4. 3. Evaluation of surgically assisted rapid maxillary expansion and orthodontic treatment : Effects on dental, skeletal and nasal structures and rhinological findings

    Författare :Anders Magnusson; Agneta Marcusson; Krister Bjerklin; Peter Nilsson; Torbjörn Ledin; Maria Ransjö; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Surgically Assisted Rapid Maxillary Expansion (SARME) is frequently used to treat skeletal maxillary transverse deficiency (MTD) in skeletally mature and non-growing individuals. Despite previous research in the field, questions remain with respect to the long-term stability of SARME and its effects on hard and soft tissue. LÄS MER

  5. 4. Biological interface of bone graft substitute materials : experimental studies on interactions between biomaterials and bone cells

    Författare :Zivko Mladenovic; Maria Ransjö; Joost D de Brujin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Bone graft substitute materials are becoming more common as alternative therapy strategies when bone defects in patients need to be treated. The interaction between bone cells and biomaterials occur at the surface of the materials. A great deal is known about the importance of surface topography and physic-chemical properties of biomaterials. LÄS MER

  7. 5. 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
