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

   Författare :Måns Jungner; Stefan Lundgren; Malou Hultcrantz; Carina Lundqvist; Peter Nilsson; Umeå universitet; []
   Nyckelord :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;

   Sammanfattning : 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. 2. On the Bone Tissue Response to Surface Chemistry Modifications of Titanium Implants

   Författare :Byung-Soo Kang; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegrated titanium implants; Magnesium and Calcium Incorporated Bioactive Titanium Oxide; Metal Plasma Immersion Ion Implantation and Deposition; Micro Arc Oxidation; Clinical Implants; In Vivo Bone Response;

   Sammanfattning : Background: Surface properties of titanium implants play an important role in osseointegration. From 1990, a lot of engineering techniques have been applied to dental implant productions for improving their clinical performance by changing surface properties. LÄS MER

4. 3. Fixation of Spinal Implants : Clinical and Experimental Studies on the Effects of Hydroxyapatite Coating

   Författare :Bengt Sandén; Acke Ohlin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Hydroxyapatite; pedicle screw; histomorphometry; fixation; radiolucent zones; screw loosening; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

   Sammanfattning : Loosening of implants is a frequent complication in orthopaedic surgery. The aim of this thesis was to evaluate hydroxyapatite coating of pedicle screws with mechanical and histological methods and to correlate the results with the radiological findings.Hydroxyapatite (HA) coating of pedicle screws was investigated in experimental studies in sheep.

5. 4. On implant integration in irradiated bone : clinical and experimental studies

   Författare :Jan Nyberg; Börje Svensson; Christer Dahlin; Carina B. Johansson; Bo Sunzel; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implant; osseointegration; radiation therapy; bone remodeling; histomorphometry; hyperbaric oxygen therapy; gene expression and in vivo; Surgery; Kirurgi;

   Sammanfattning : Radiation has an impact on the processes involved in bone- healing, regeneration and remodeling. The mechanisms that cause impaired bone healing of dental implants are not fully understood. Adjunctive treatments to revers radiation effects are limited. LÄS MER

7. 5. Studies on Cervical Artificial Disc Replacement

   Författare :Catarina Marques; Claes Olerud; Anna MacDowall; Martin Skeppholm; Adrian Elmi Terander; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cervical radiculopathy; artificial disc replacement; Orthopaedics; Ortopedi; Neurokirurgi; Neurosurgery;

   Sammanfattning : Artificial disc replacement (ADR) was developed as an alternative to anterior fusion after decompression for cervical degenerative radiculopathy. By preserving motion, it was expected to prevent acceleration of adjacent segment pathology (ASP) associated with fusion, and lead to better clinical outcomes. LÄS MER
