  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. On bone quality and implant stability measurements

    Författare :Bertil Friberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; early failures; titanium implants; jaw bone quality; jaw bone volume; cutting torque; implant stability; resonance frequency; one-stage surgery;

    Sammanfattning : In conjuction with placement of oral implants, the jaw bone quality assessment is mainly based on quantitative radiographic measures and the subjective opinion of the performing surgeon. While the primary implant stability is discussed in terms of the pre-set motor torque and the subjective hand-felt perception during final tightening of implants, the secondary stability is defined as the absence of implant mobility.

  4. 3. On failure of oral implants

    Författare :Bruno Chrcanovic; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Introduktion: Behandling med orala implantat är idag en effektiv och fungerande metod att ersätta bettfunktion vid partiell eller hel tandlöshet. Trots höga överlevnads- och lyckandesiffror finns ändå riskfaktorer som för vissa patienter kan resultera i implantatförlust. LÄS MER

  5. 4. The effect of tobacco exposure on bone healing and the osseointegrationof dental implants

    Författare :Shariel Sayardoust; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; crevicular fluid; dental implants; gene expression; human; implant surfaces; implant survival; marginal bone loss; osseointegration; pain; periodontitis; resonance frequently analysis; smoking; titanium;

    Sammanfattning : Background: The mechanisms behind the impact of smoking on osseointegration are not fully understood. Aim: To correlate the clinical and molecular aspects of osseointegration in smokers compared with non-smokers. LÄS MER

  7. 5. Bone grafts and dental implants in the reconstruction of the severely atrophied, edentulous maxilla

    Författare :Björn Johansson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; dental implants; maxilla; grafted bone; implant failure; clinical study; computed tomography; cutting torque; Kirurgi; Surgery; Kirurgi; plastikkirurgi; Plastic Surgery;

    Sammanfattning : In two prospective, clinical studies the stability of implants and prosthetic constructions were evaluated after three years of loading. In the first study, the implant and the bridge stability of 39 patients with 1-stage bone grafts, were compared to a reference-group of 37 patients who did not need bone grafts. LÄS MER
