2. 1. An injectable biphasic bone substitute in sinus augmentation

   Author : Anna Truedsson; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dentala implantat; Dental Implants; Bone transplantation; Bone substitutes;

   Abstract : This thesis concerns a new synthetic, injectable bone substitute, Cerament™, primarily developed for treatment of vertebral fractures. The purpose of the thesis was to investigate the properties of the newbone substitute, that is, whether it can contribute to the generation of new bone formation needed for placement of future dental implants.

4. 2. Following the mevalonate pathway to bone heal alley

   Author : Björn Skoglund; Lars Nordsletten; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bone screws; coated materials; biocompatible; chemistry; diphosphonates; pharmacology; Equipment failure analysis methods; Femoral fractures; drug therapy; fracture fixation; instrumentation; Fracture fixation; fracture healing; drug effects; simvastatin; tibial fractures; physiopathologyial fractures; surgery; Pharmaceutical chemistry; Farmaceutisk kemi; Other veterinary medicine; Övrig veterinärmedicin;

   Abstract : The mevalonate pathway is an important biosynthetic pathway, found in all cells of virtually all known pro- as well as eukaryotic organisms. This thesis is an investigation into the use of two drugs, originally developed for different applications, but both affecting the mevalonate pathway, in to models of fracture repair. READ MORE

5. 3. Mechanical optimization of orthopaedic bone screw constructs

   Author : Yijun Zhou; Cecilia Persson; Benedikt Helgason; Philip Procter; Richie Gill; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; screw implant; explicit finite element modelling; computed tomography; numerical optimization; neural network; hydrogel; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

   Abstract : Orthopaedic screw implants are crucial in surgical procedures for bone structures, with a longstanding issue being screw loosening. Improving screw stability requires an enhanced understanding of the bone-implant interactions and associated failure mechanisms. This knowledge can be used to optimize screw designs. READ MORE

6. 4. Mechanical analyses of trabecular bone and its interaction with implants

   Author : Dan Wu; Cecilia Persson; Hanna Isaksson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; Elastic modulus; Digital volume correlation; Pullout resistance; Micro-computed tomography.;

   Abstract : Bone substitute materials or implants are commonly used in the surgical treatment of bone fractures. However, severe complications are sometimes reported. READ MORE

7. 5. On guided bone regeneration using ceramic membranes

   Author : Jonas Anderud; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Regeneration of bone in the oral and maxillofacial region can beachieved with different techniques such as autologous bone grafts,bone substitutes and guided bone regeneration. Guided boneregeneration is defined as creating a space between the bone and itssurrounding tissues, using a barrier that allows new bone to migrateinto the space while preventing other cell types from interfering.
