1. 1. Children with Cochlear Implants : Cognition and Reading Ability

   Författare :Malin Wass; Björn Lyxell; Birgitta Sahlén; Birgitta Larsby; Anita McAllister; Linköpings universitet; []
   Nyckelord :Cochlear implants; children; working memory; phonological skills; lexical access; reading ability; Cochleaimplantat; barn; arbetsminne; fonologiska färdigheter; lexikal aktivering; läsförmåga.; MEDICINE; MEDICIN;

   Sammanfattning : The present thesis investigated cognitive ability in children with severe to profound hearing impairment who have received cochlear implants (CIs). The auditory stimulation from a cochlear implant early in life influences most cognitive functions as a consequence of the plasticity of the brain in the young child. LÄS MER

3. 2. On customization of orthopedic implants - from design and additive manufacturing to implementation

   Författare :Marie Cronskär; Mats Tinnsten; Mikael Bäckström; Lars-Erik Rännar; Mittuniversitetet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Hälsoekonomisk analys av dentala implantat

   Författare :Göran Karlsson; Linköpings universitet; []

   Sammanfattning : This study focuses on economic analysis of dental implants. The purposewas to analyse how optimal use of resources within dental care is affectedby the introduction of dental implants. LÄS MER

5. 4. Functional Aspects of Cranial Implants : Mechanical and Regenerative Properties

   Författare :Susanne Lewin; Caroline Öhman-Mägi; Cecilia Persson; Harry van Lenthe; Uppsala universitet; []
   Nyckelord :Calcium phosphate; Ti-6Al-4V; composites; mechanical properties; finite element methods; cranial implants; computed tomography; quantitative image analysis; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Sammanfattning : In several neurosurgical procedures, the skull must be temporarily opened. The resulting bone defect can subsequently be reconstructed with a cranial implant. However, the complication rate of this surgical procedure is high (~20%). The most common complication for cranial implants is infection. LÄS MER

7. 5. Soft tissue integration to dental implants

   Författare :Maria Welander; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; connective tissue; dental implants; epithelium; gold alloy; histology; peri-implant mucosa; subcrestal placement; titanium; zirconia;

   Sammanfattning : Soft tissue integration is a prerequisite for implant success. The role of the soft tissue barrier at implants is to provide an effective seal that protects the underlying bone and prevents access for microorganisms and their products. LÄS MER
