  1. 1. Conventional spiral and low-dose computed mandibular tomography for dental implant planning

    Författare :Annika Ekestubbe; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Artifacts; Dental Implantation; Endosseous; methods; Dental Implants; Humans; Jaw; Edentulous; radiography; Mandible; radiography; Patient Care Planning; Phantoms; Imaging; Radiation Dosage; Radiography; Dental; methods; Reproducibility of Results; Tomography; X-Ray; instrumentation; methods; Tomography; X-Ray Computed; methods;

    Sammanfattning : Absorbed doses to radiosensitive organs in the head and neck from pre-implant conventional hypocycloidal, conventional spiral and computed tomography (CT) were measured with thermoluminescent dosimeters in an anthropomorphic phantom head. From conventional tomography organ doses, except to the major salivary glands, were below 0.2 mGy. LÄS MER

  3. 2. Cone Beam Computed Tomography - radiation dose and image quality assessments

    Författare :Sara Lofthag-Hansen; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cone beam computed tomography; anatomic landmarks; dose-area product; image quality; implant planning; periapical diagnosis; radiation dosimetry;

    Sammanfattning : Diagnostic radiology has undergone profound changes in the last 30 years. New technologies are available to the dental field, cone beam computed tomography (CBCT) as one of the most important. LÄS MER

  4. 3. 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

  5. 4. On the Clinical Outcome of Different Single Implant Treatment Modalities

    Författare :Björn Gjelvold; Umeå universitet Molin Thorén; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Today there are several treatment techniques available to replace a missing tooth. Since the beginning of the 1990s, it has become increasingly common to treat individual tooth loss with dental implants. Important patient factors are survival, success, functionality, aesthetics, oral health and quality of life. LÄS MER

  7. 5. Metal artifacts in computed tomography : impact of reduction methods on image quality and radiotherapy treatment planning

    Författare :Karin Andersson; Per Thunberg; Eva Norrman; Jan Persliden; Anders Tingberg; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computed tomography; metal artifacts; image quality; visual grading analysis; radiotherapy; proton therapy; hip prosthesis; dental implants;

    Sammanfattning : Degradation of image quality by metal artifacts is a common problem in computed tomography (CT) imaging, which can limit the diagnostic value of a CT examination and also introduce inaccuracies in radiotherapy (RT) treatment planning. In recent years, commercial metal artifact reduction (MAR) methods have been launched by several CT vendors. LÄS MER
