2. 1. Mesoporous Implants for Localized Controlled Drug Delivery

   Author : Johan Karlsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; release kinetics; mesoporous titania; biomineralization; drug delivery; Biomedical implants; osseointegration; osteoporosis drugs; nanotopography; stem cells homing;

   Abstract : The use of bone-anchored implants is today a routine treatment for patients with normal regenerative capacity. However, there is an ongoing development within implant research to improve the osseointegration of implants. READ MORE

4. 2. Mechanism-based flow stress model for Ti-6Al-4V : applicable for simulation of additive manufacturing and machining

   Author : Bijish Babu; Lars-Erik Lindgren; Jean-Philippe Ponthot; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material modeling; Ti-6Al-4V; dislocation density; vacancy concentration; additive manufacturing; hot forming; heat treatment; Material Mechanics; Materialmekanik;

   Abstract : Ti-6Al-4V has remarkable properties such as high specific mechanical properties (viz. stiffness, strength, toughness, fatigue resistance), corrosion resistance, biocompatibility etc. These properties make it attractive for applications in aerospace, chemical industry, energy production, surgical implants, etc. READ MORE

5. 3. Macrophage-material surface interactions

   Author : Christina Gretzer; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

   Abstract : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. READ MORE

6. 4. On customization of orthopedic implants - from design and additive manufacturing to implementation

   Author : Marie Cronskär; Mats Tinnsten; Mikael Bäckström; Lars-Erik Rännar; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Patient-specific implants; Additive manufacturing; Electron beam melting; Multibody musculoskeletal analysis; Orthopedic implants; Clavicle; Finite element analysis; Computer aided design; Osteosynthesis plate; Hip stem implants;

   Abstract : This doctoral thesis is devoted to studying the possibilities of using additive manufacturing (AM) and design based on computed tomography (CT), for the production of patient-specific implants within orthopedic surgery, initially in a broad perspective and, in the second part of the thesis focusing on customized clavicle osteosynthesis plates. The main AM method used in the studies is the Electron Beam Melting (EBM) technology. READ MORE

7. 5. Silicon nitride based coatings for biomedical implants

   Author : Charlotte Skjöldebrand; Cecilia Persson; Håkan Engqvist; Julia Shelton; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon nitride; ceramic coating; deposition; PVD; dissolution; biocompatibility;

   Abstract : Silicon nitride-based coatings have been proposed as a means to reduce the release of metal ions and debris from metallic implants. This reduction in combination with the biocompatible debris from silicon nitride could result in a less adverse immune response. READ MORE
