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

   Author : Catharina Göthberg; Göteborgs universitet; []
   Keywords : 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;

   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

4. 2. On cobalt-chrome frameworks in implant dentistry

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

   Abstract : 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. READ MORE

5. 3. On platelet-rich plasma in reconstructive dental implant surgery

   Author : Andreas Thor; Göteborgs universitet; []
   Keywords : autogenous bone graft; bone formation; coagulation; clinical study; complement; dental implant; experimental study; growth factors; platelet activation; platelet-rich plasma; sinus lift surgery; thrombogenicity;

   Abstract : Abstract Background Severe athrophy of the edentulous maxilla may require augmentation before implants can be placed. Autogenous bone has been used for reconstruction in block or in particulated form. READ MORE

6. 4. On percutaneous implants fate and feature

   Author : Anna Larsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydroxyapatite; Bone anchored hearing aid; Percutaneous; Abutment; Dermal integration;

   Abstract : Abstract The main objective of this thesis was to investigate skin reactions around percutaneous abutments in the facial and retroauricular regions. Secondary objectives were to investigate the number of lost extraoral implants and their co-morbidity over time, for example complications because of skin reactions due to the skinpenetrating abutment.

7. 5. A methodological platform to study molecular biocompatibility of biomaterials. Experimental and clinical studies

   Author : Maria Lennerås; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegration; titanium; inflammation; cell recruitment; cell adhesion; bone regeneration; bone remodelling; gene expression; immunohistochemistry; histomorphometry; removal torque; ultrastructure; FACS; protein profiling; transfemoral amputation; abutment; percutaneous; bacteria; clinical signs;

   Abstract : The aim of this project was to develop a methodological platform in order to advance our scientific understanding of the mechanisms of osseointegration. Screw-shaped, titanium implants, with different surface properties, were inserted in the rat tibia, or incubated in mono- or co-culture of human monocytes and MSCs. READ MORE
