1. 6. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

   University essay from Lunds universitet/Materialteknik

   Author : Johan Ranstad; [2023]
   Keywords : Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

   Abstract : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. READ MORE

3. 7. Difference in Marginal Bone Loss Around Implants Between ShortImplant-Supported Partial Fixed Prostheses With and Without Cantilever : A Retrospective Clinical Study

   University essay from Malmö universitet/Odontologiska fakulteten (OD)

   Author : Josef Al-Kilani; Sedef Al-Kilani; [2023]
   Keywords : Implant-supported fixed partial prosthesis; cantilever; marginal bone loss;

   Abstract : Abstract  Objective:The aim of this retrospective study was to examine the influence of a cantilever on marginal bone loss (MBL) around dental implants supporting 3-unit partial fixed prostheses.  Materials and methods:Retrospective data were collected from dental records of patients at a specialist clinic in Malmö, Sweden, covering the period from 1980 to 2018.

5. 9. ​​​Biological characterization of a novel biomaterial​​ : ​​In vitro studies of a biodegradable Mg-Ca alloy​

   University essay from Uppsala universitet/Institutionen för medicinsk cellbiologi

   Author : Emma Gonzales Vall; Alma Gårdman; [2023]
   Keywords : Mg-Ca alloy; biological evaluation; biocompatibility; biodegradable implant;

   Abstract : Biodegradable implants continue to be of interest in orthopaedics for their many potential applications. The magnesium (Mg) alloy WE43 is a biodegradable material with the CE mark approval for clinical application and today mostly used as screws for dental prosthesis. READ MORE

6. 10. Inclusion of more sources in a commercial brachytherapy Monte Carlo

   University essay from

   Author : Philip Wiman; Emil Forsberg; Robin Vestling; [2023]
   Keywords : ;

   Abstract : Brachytherapy is a cancer treatment method where a solid radioactive source is placed inside the body in order to target cancer cells with a high dose of radiation while minimizing damage to surrounding healthy tissue. The most common method for treatment planning in brachytherapy is the TG43 formalism where the whole patient geometry is treated as water. READ MORE
