1. Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements
Sammanfattning : The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. LÄS MER
2. Calcium Phosphate Based Biomaterials for Bone Augmentation
Sammanfattning : Basic (apatite-based) calcium phosphate cements (CPCs), and acidic (brushite and monetite-based) CPCs are used as bone replacement materials because of their bioactivity, mouldability and ability to harden in place. However, their application is limited by their inherent brittleness and difficulties related to their handling. LÄS MER
3. Solubility and Surface Complexation Studies of Apatites
Sammanfattning : Apatites are a diverse class of phosphate minerals that are important in a great variety of natural and industrial processes. They are, for example, used as raw material in fertiliser production and in the remediation of metal-contaminated soils. LÄS MER
4. Can Bone Void Fillers Carry Load? : Behaviour of Calcium Phosphate Cements Under Different Loading Scenarios
Sammanfattning : Calcium phosphate cements (CPCs) are used as bone void fillers and as complements to hardware in fracture fixation. The aim of this thesis was to investigate the possibilities and limitations of the CPCs’ mechanical properties, and find out if these ceramic bone cements can carry application-specific loads, alone or as part of a construct.

5. Osteocytes as indicators of bone quality - multiscale structure-composition characterisation of the bone-implant interface
Sammanfattning : By virtue of certain design features, bone anchored metal implants can be made to elicit a strong initial osteogenic response, i.e., the amount of bone formed. LÄS MER
