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. On dental implant failure and patient-related factors

   Författare :Malin Olsson Malm; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implants; implant failure; long term; implant surface; multivariable logistic regression; case-control study; edentulous jaw; gene expression analysis; early implant failure; patient factors;

   Sammanfattning : Dental implants function as anchorage for dental prostheses. In a small number of cases, osseointegration fails to establish or be maintained around the implants, but the reasons for these failures are not yet fully understood. LÄS MER

4. 3. Single crystal sapphire dental implants : experimental and clinical studies

   Författare :Bahman Fartash; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :edentulous mandible; implantology; sapphire dental implants; overdenture; long-term follow-up; radiography; osseointegration; peri-implant mucosa; corrosion; cell culture; animal experiments; light microscopy; scanning electron microscopy; histometri;

   Sammanfattning : The aim of this project was to evaluate single synthetic sapphire crystals as dental implants, with special reference to correlation of clinical and in vitro/in vivo methods of research. The laboratory studies confirmed chemical stability. LÄS MER

5. 4. On the role of number of fixtures, surgical technique and timing of loading

   Författare :Alf Eliasson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Computer numerical control; dental implants; fixed prostheses; non-submerged; CNC-milling;

   Sammanfattning : Aims: The aims of this thesis were to analyze reduced number of implants supporting full arch fixed mandibular prostheses and fixed partial dentures (FPDs), non-submerged healing and early loading in the edentulous mandible. A further aim was to evaluate fit of Computer Numerical Control (CNC)-milled I-Bridge? frameworks. LÄS MER

7. 5. Accuracy of virtually planned and CAD/CAM-guided dental implant surgery

   Författare :Andreas Pettersson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :dental implant;

   Sammanfattning : The treatment with dental implants was introduced in the 1960s as an aid for patients who were missing teeth. Recently CAD/CAM guided surgical concepts have been launched on the market as a solution for treating single, partial or completely edentulous patients with dental implants. LÄS MER
