  1. 11. Radiographic follow-up analysis of Br?nemark? dental implants

    Författare :Solweig Sundén Pikner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cluster effect; Dental implants; Dependency; Diagnostic accuracy; Long-term follow-up; Marginal bone level; Observer variation; Osseointegration; Prediction;

    Sammanfattning : Radiography plays an important role in clinical routine practice and in research projects evaluating dental implants, among them Br?nemark? System. Presence of a peri-implant radiolucency has been used in studies as a criterion for implant failure without knowledge of its diagnostic accuracy. LÄS MER

  3. 12. Orthodontically induced root resorption: a clinical and radiographic survey

    Författare :Dimitrios Makedonas; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontics; root resorption; prediction; CBCT; Angle Class I; fixed appliance; six month; risk factors;

    Sammanfattning : In 2005 the Swedish Council on Health Technology Assessment (SBU), in a systematic review, Malocclusions and Orthodontic Treatment in a Health Perspective, concluded that there were low or contradicted evidence for an association between orthodontic treatment and the risks for negative side effects. The aims of this study was to evaluate the perception of Greek and Swedish orthodontic practitioners view on orthodontically induced root resorption (OIRR), to investigate how root resorption is handled in a large orthodontic clinic and to prospectively study and correlate the prevalence and severity of root resorption seen after an initial treatment period and at the end of treatment, in a cohort of patients treated with fixed appliance.

  4. 13. Optimisation of radiographic imaging by means of factorial experiments

    Författare :Eva Norrman; Jan Persliden; Andreas Oberstedt; Bertil Axelsson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Fysik; Physics;

    Sammanfattning : In the optimisation process of radiographic imaging, factorial designed experiments can be applied. The parameters (factors) are varied together instead of one at a time, making it possible to discover interactions between the factors as well as main influences of them on the result variable.

  5. 14. Radiographic imaging in relation to the mandibular third molar : tooth characteristics, modality choice, optimization, and absorbed dose

    Författare :Josefine Cederhag; Kristina Hellén-Halme; Henrik Lund; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Radiographic imaging of the mandibular third molar (M3) is a valuable diagnostic tool. It provides information on tooth position, root morphology, and relations to surrounding anatomical structures that facilitates diagnosis and treatment planning. LÄS MER

  7. 15. Radiographic assessment of cup migration and wear after hip replacement

    Författare :Thomas Ilchmann; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; measurement; assessment; loosening; migration; wear; cup; Hip; arthroplasty; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Methods are needed for accurate measurement of acetabular cup migration and wear after hip replacement. The EBRA (Ein Bild Röntgen Analyse) method was recently introduced as a computerized method for radiographic assessment of acetabular cup migration. LÄS MER
