  1. 1. 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

  3. 2. 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

  4. 3. On loading protocols and abutment use in implant dentistry. Clinical studies

    Författare :Catharina Göthberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; abutment design; clinical studies; dental implants; dental prosthesis; implant-supported; gene expression; health; immediate implant loading; marginal bone loss; osseointegration; prosthodontics; risk factors; smoking; treatment outcome;

    Sammanfattning : ABSTRACT Research questions: The influence of immediate or delayed loading and the use of abutments in implant dentistry with regard to peri-implant tissues and the effect of risk parameters. Methodology: Fifty partially edentulous patients each received three Brånemark TiUnite™ implants. LÄS MER

  5. 4. Decontamination of implant surfaces

    Författare :Yuki Ichioka; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental implant; peri-implantitis; surface decontamination;

    Sammanfattning : Peri-implantitis is a pathological condition occurring in tissues around dental implants. It is caused by microorganisms and characterized by inflammation in the peri-implant connective tissue and progressive loss of supporting bone. The goal of treatment of peri-implantitis is to resolve inflammation and to arrest further loss of supporting bone. LÄS MER
