  2. 1. On nano size structures for enhanced bone formation

    Author : Luiz Meirelles; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nano structures; nanotopography; surface modification; osseointegration; bone tissue; titanium implants;

    Abstract : Purpose The general aim of the present thesis was to investigate early bone response to titanium implants modified with nano size structures. Therefore, 1. a model to evaluate titanium implants modified with nano size structures was validated; 2. a suitable detection method of nano size structures was implemented. READ MORE

  4. 2. 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

  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. 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

  7. 5. On enhancement of bone formation using local drug delivery systems

    Author : Ali Alenezi; Ann Wennerberg; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone formation; local drug delivery systems;

    Abstract : Introduction: Despite that many reports have confirmed the long-term clinical success rates associated with implant treatment, implant failure to achieve and maintain osseointegration still occurs in many cases. Local and sustained drug release at the bone-implant interface is one of the strategies that have been suggested to improve the osseointegration. READ MORE
