  1. 1. Aspects of oral implant technology and osseointegration

    University dissertation from Malmö universitet, Faculty of Odontology

    Author : Rainde Naiara Rezende de Jesus; Malmö University.; [2019]
    Keywords : ODONTOLOGY; ODONTOLOGI; Medicine; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

    Abstract : Implant rehabilitation of edentulous patients is a predictable treatment with high long-term survival rates (90-95%) reported for the major dental implant systems after 5-10 years in function. Throughout recent years, different materials, implant surface technologies, macrodesigns, and surgical techniques have been developed to enhance osseointegration and lessen treatment timeframes, for example allowing immediate or early functional loading in patients with reduced bone density.

  2. 2. Healing of endosseous implants with different surface characteristics in grafted and non-grafted bone clinical and experimental studies

    University dissertation from Umeå : Umeå Universitet

    Author : Måns Jungner; Umeå universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental implants; surface characteristics; bone graft; maxillary sinus; implant survival; oxidized surface; turned surface; sinus membrane elevation; bone formation; macrophages; osteocalcin; osteopontin; CD68; odontologi; Odontology;

    Abstract : Aims: This study uses radiological and clinical evaluations of the healing of endosseous titanium implants presented with different surface characteristics in the clinical situation (paper I-III) and experimentally to describe the early bone healing in maxillary sinus membrane elevation with and without the use of grafting material (paper IV).Material and methods: In paper I, 136 patients were treated with 394 dental implants – 199 were oxidized titanium implants (Nobel Biocare TiUnite) and 195 were turned titanium surface implants (Nobel Biocare Mark III).

  3. 3. On Ca2+ incorporation and nanoporosity of titanium surfaces and the effect on implant performance

    University dissertation from Malmö University, Department of Prosthetic dentistry

    Author : Victoria Fröjd; Malmö University.; [2010]
    Keywords : ODONTOLOGY; ODONTOLOGI; MEDICINE; MEDICIN; Medicine; dental implants; osseointegration; biofilms; oral mucosa;

    Abstract : Introduction: Titanium implants are commonly used as replacements for missing teeth with successful long-term performance. The aim of the research performed in the field is to enable successful osseointegrated implant treatments for compromised as well as healthy bone beds, and to establish a rapid osseointegration to shorten the treatment period for the patients.

  4. 4. Characterising Dental Implant Surfaces by Topographical, Electrochemical, and Biomechanical Methods

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Johanna Löberg; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titanium dental implants; 3D-SEM; AFM; Mott-Schottky analysis; surface roughness parameters; biomechanics.;

    Abstract : Replacement of extracted teeth by dental implants was first introduced in the 1950’s. From the beginning, threaded titanium implants with smooth surfaces were used. Later on, screw shaped implants with micro-scaled roughened surfaces were introduced showing bone ingrowth and improved in vivo and in vitro results and good long term stability. READ MORE

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

    University dissertation from Göteborg : University of Gothenburg

    Author : Catharina Göthberg; Göteborgs universitet.; Gothenburg University.; [2016]

    Abstract : 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. READ MORE
