  1. 16. 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

  3. 17. On healing of titanium implants in iliac crest bone grafts

    Författare :Mats Sjöström; Stefan Lundgren; Lars Sennerby; Christian Lindqvist; Umeå universitet; []
    Nyckelord :Surgery; Edentulous atrophic maxilla; Autogenous bone graft; Endosteal implants; Microimplants; Resonance frequency analysis; Implant survival; Graft volume changes; Kirurgi; odontologi; Odontology;

    Sammanfattning : Bone grafts and titanium implants are commonly used for surgical/prosthetic rehabilitation of the atrophic edentulous maxilla. The factors which influence bone graft healing and implant integration are not sufficiently understood. LÄS MER

  4. 18. Tissue reactions to biomaterials

    Författare :Agneta Rosengren; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytochemistry; Histology; Macrophages; Cryosubstitution; Proteins; Immunohistochemistry; Titanium; Implants; PTFE; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Sammanfattning : The biological response to different implanted biomaterials vary. The relative importance of factors in the material and host for this variation are at present incompletely known. LÄS MER

  5. 19. On the tissue response to hafnium, titanium and thin calcium phosphate coatings

    Författare :Sham Mohammadi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hafnium; titanium; calcium phosphates; hydroxyapatite; implants; bone; soft tissue; histomorphometry;

    Sammanfattning : Background: Titanium (Ti) is the gold standard material for load-bearing implants. Although high success rates have been reported for Ti implants, failures do occur. Alternative materials/surface modifications might further improve the performances of Ti implants, particularly in situations with non-optimal local tissue conditions. LÄS MER

  7. 20. On cobalt-chrome frameworks in implant dentistry

    Författare :Lars Hjalmarsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cobalt-chrome; titanium; implants; misfit; corrosion; viability; abutment-free;

    Sammanfattning : Background: Cobalt-chrome (CoCr) alloys have been used in dentistry in decades but very little is known about their behavior and biological impact as framework materials in implant dentistry. Furthermore, few studies have evaluated and compared the clinical and radiological results of abutment and abutment-free implant treatment concepts. LÄS MER
