  1. 1. Reactions with relativistic radioactive beams and gamma multiplicities

    Författare :Simon Lindberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; R3B; Calibration; Radioactive Beams; FAIR; Gamma Multiplicity; Analysis; Virtual Alignment; GSI;

    Sammanfattning : Experiments with relativistic radioactive beams are used to study the properties of exotic nuclei. The experimental setup used in this thesis is a complex system of detectors for identifying and measuring the 4-momenta of all incoming nuclei and products created when the nuclei impinge on a reaction target.

  3. 2. Virtual three-dimensional analysis of digitized dental impressions and stone replicas

    Författare :Anna Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Accuracy; alignment software; computer-aided analysis; computer-aided design; computer-aided manufacturing; fixed prosthodontics; precision; reliability; reproducibility; surface digitization devices;

    Sammanfattning : In response to increasing patient awareness of esthetic dental rehabilitation, the preference today is for all-ceramic restorations, which show superior biocompatibility and similar light characteristics to the natural tooth. The fit of a dental restoration depends on quality throughout the entire manufacturing process. LÄS MER

  4. 3. Influence of deciduous canine extractions on incisor alignment, dental arch dimensions and dental fear

    Författare :Anders Sjögren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Interception of crowding, by extraction of deciduous and permanent teeth, to eliminate or at least facilitate orthodontic treatment has a long tradition. This treatment procedure, know as “guided eruption” or “serial extraction” was re-introduced by Robert Hotz and Birger Kjellgren in 1947-48. LÄS MER

  5. 4. Haptics with Applications to Cranio-Maxillofacial Surgery Planning

    Författare :Pontus Olsson; Ingrid B. Carlbom; Blake Hannaford; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; medical image processing; haptics; haptic rendering; haptic gripper; visuo-haptic co-location; vibrotactile feedback; surgery simulation; virtual surgery planning; cranio-maxillofacial surgery; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Virtual surgery planning systems have demonstrated great potential to help surgeons achieve a better functional and aesthetic outcome for the patient, and at the same time reduce time in the operating room resulting in considerable cost savings. However, the two-dimensional tools employed in these systems today, such as a mouse and a conventional graphical display, are difficult to use for interaction with three-dimensional anatomical images.

  7. 5. Evaluation of computer-assisted virtual treatment planning and template-guided surgery in dental implant treatment

    Författare :Ai Komiyama; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dental implant; computer-guided surgery; surgical template; flapless surgery; immediate loading; CAD CAM technique; marginal bone loss; soft tissue condition; accuracy;

    Sammanfattning : One of the newly introduced concepts in implant dentistry is computer-guided surgery. The development of 3D implant planning software and imaging technology provide clinicians with 3D information of patients bony structures. LÄS MER
