1. Calcium Aluminate based Cement as Dental Restorative Materials
Abstract : This thesis presents the results from the development process of a ceramic dental filling material based on calcium aluminate cement. The main focus of the work concerns dimensional changes during setting, hardening and curing and the understanding of the factors controlling the dimensional stability of the system. READ MORE

2. Optimization of Electron Beam Melting for Production of Small Components in Biocompatible Titanium Grades
Abstract : Additive manufacturing (AM), also called 3D-printing, are technologies where parts are formed from the bottom up by adding material layer-by-layer on top of each other. Electron Beam Melting (EBM) is an AM technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers to form finished components.

3. A multidisciplinary risk assessment of dental restorative materials
Abstract : Amalgam has been used as a dental restorative material for centuries, but its potential health effects and biopersistance has lead to a decreased use especially in the Nordic countries. New materials have been introduced, partly to replace the mercury containing amalgam and partly because of esthetical reasons. READ MORE

4. Biomaterial Components Prepared by Titanium Powder Technology
Abstract : The main objectives of this work were twofold: First, to determine if a pressed-powder method could be used to fabricate titanium dental copings, and to line out what problems or benefits this new method would have. Second, to test if high velocity compaction of titanium powder could be used to form biomaterial components such as copings or dental implants. READ MORE
