2. 6. 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

4. 7. On efficacy of implant thread design for bone stimulation

   Author : Ramesh Chowdhary; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Introduction – The mechanism and efficiency of force transfer by dental implants to surrounding biologic tissues are important determinants in the development of the implant-to-bone/tissue interface and implant longevity. Threads are used to improve the initial stability by maximizing bone contact through an enlarged implant surface area and thereby favor distribution of interfacial stresses. READ MORE

5. 8. On a biomechanical approach to analysis of stability and load bearing capacity of oral implants

   Author : Anders Halldin; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animal model; bone resorption; implant stability; cortical bone; viscoelastic-viscoplastic; creep remodeling; constitutive model;

   Abstract : IntroductionWhen an implant is placed in the bone the body responds to thetrauma by encapsulating the implant and its survival depends onthe ability for hard tissue encapsulation. The stability of the implantduring the healing phase is essential to achieve a good result[1]. Biological, physiological and mechanical phenomena affectimplant stability. READ MORE

6. 9. Novel Materials and Implant Designs for the Treatment of Degenerative Disc Disease

   Author : Salim Ghandour; Cecilia Persson; Donal McNally; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Topology Optimization; Spine; Intervertebral Disc; Papain; Additive Manufacturing; Biomechanics; Bone Cement; PMMA; Calcium Phosphate; Cage; Fusion; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

   Abstract : The overarching objective of this thesis was to develop intervertebral implants for degenerated discs through design, fabrication, and mechanical validation. The research had four primary aims, each addressing different facets of implant development. READ MORE

7. 10. Biomechanical Analysis of Stress and Stiffness of New Load-Bearing Implants

   Author : Jinxing Huo; E. Kristofer Gamstedt; Benedikt Helgason; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

   Abstract : Medical implants are essential products for saving lives and improving life quality. Nowadays, the demand for implants, especially biocompatible and personalized ones, is increasing rapidly to deal with factors like congenital malformations, aging, and increasing prevalence of cancer.
