2. 1. On dental ceramics and their fracture : a laboratory and numerical study

   Author : Wen Kou; Göran Sjögren; Tore Dérand; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental ceramics; Finite element analysis; Fixed partial denture; Fracture; Numerical modeling; Surface treatment; Biomaterials; Biomaterial; odontologi; Odontology;

   Abstract : Background Surface treatments and irregularities in the surfaces may affect the fracture of ceramics. The effects of various treatments on the surface texture of different types of ceramic cores/substructures was therefore qualitatively, quantitatively and numerically evaluated. READ MORE

4. 2. A multidisciplinary study of patients with signs or symptoms attributed to dental restorative materials

   Author : Lena Mårell; Anders Berglund; Jan Bergdahl; Berndt Stenberg; Nils-Roar Gjerdet; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental restorative materials; environmental intolerance; oral lichen; personality; self-image; psychological symptoms; odontologi; Odontology;

   Abstract : Anxiety for adverse health effects attributed to dental restorative materials especially dentalamalgam, have been discussed extensively off and on the last 30 years. The possible health effect ofamalgam and health effect of replacements of amalgam, have been extensively studied but theresults are inconclusive and the etiology of the reactions are not entirely elucidated.

   Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.

6. 4. On magnesium-modified titanium coatings and magnesium alloys for oral orthopaedic applications : in vitro investigation

   Author : Francesca Cecchinato; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biocompatible material; Bone substitutes; Biomaterial; Dentala implantat;

   Abstract : In dentistry and orthopaedic surgery, research to find and developimproved biomaterials is progressing rapidly.Of specific interest is to accelerate bone formation around theimplant surface, which could improve the reliability of the implanteven in patients with compromised situations.

7. 5. On hydroxyapatite modified peek implants for bone applications

   Author : Pär Johansson; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental Implants; Dentala implantat;

   Abstract : People are living longer today than ever before, and the number of older adults will increase exponentially over the next coming years. However, that does not necessarily mean that they are living healthier. READ MORE
