   Author : Johan Forsgren; Håkan Engqvist; Strømme Maria; Susanne Bredenberg; Pentti Tengvall; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Controlled release; geopolymer; sol-gel; opioid; oral administration; oral dosage form; implant; titanium; hydroxyapatite; infection; strontium carbonate; strontium; Functional materials; Funktionella material; Materials science; Teknisk materialvetenskap; Material physics with surface physics; Materialfysik med ytfysik; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

   Abstract : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. READ MORE

4. 22. Wear characteristics of materials for artificial hip joints

   Author : Mohammed Seyed Hoseini Nazari; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HDPE; UHMWPE; Coating; Tribology; Pin-on-disc; Y-irradiation; Vitamin E; Wear; Implant; Artificial hip joint;

   Abstract : Total hip prostheses have succeeded in significantly improving the quality of life of millions of patients worldwide. Ultra high molecular weight polyethylene (UHMWPE) has been widely and successfully used as a bearing material in orthopaedic prostheses since the 1960s. READ MORE

5. 23. Insulin-coated titanium implants - a potential therapy for local bone regeneration

   Author : Behnosh Öhrnell Malekzadeh; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Insulin; Titanium; Bone; Implant; Osteoblast; Immobilisation;

   Abstract : Background: Insulin is a hormone that regulates glucose metabolism, however, it is also important for bone formation. The anabolic effect of insulin on bone could open up alternative therapies when it comes to local bone regeneration. However, this requires a method for local administration of insulin. READ MORE

6. 24. Mechanics and Growth of Articular Cartilage Around a Localized Metal Implant

   Author : Krishnagoud Manda; Anders Eriksson; Nico Verdonschot; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; articular cartilage defects; growth; knee; focal knee resurfacing; metal implant; poroelastic; porohyperelastic; biphasic;

   Abstract : Articular cartilage is a specialized connective soft tissue that resides on the ends of long-bones, and transfers the load smoothly between the bones in diarthrodial joints by providing almost frictionless, wear resistant sliding surfaces during joint articulation. Focal chondral or osteochondral defects in articular cartilage are common and show limited capacity for biological repair. READ MORE

7. 25. On various protocols for direct loading of implant-supported fixed prostheses

   Author : Pär-Olov Östman; Göteborgs universitet; []
   Keywords : dental implants; immediate loading; clinical studies; radiography; implant stability; resonance frequency analysis;

   Abstract : Backgrund: Prosthetic rehabilitation of the edentulous patient with implant-supported bridges is today a routine and predictable treatment modality. The original protocol prescribed a healing period of 3 to 6 months prior to loading which means that the total treatment time can be extensive and that the patients often need to wear removable provisional prostheses during healing and treatment.
