In calcium phosphate ceramics, hydroxyapatite (HAP) can form chemical bonding with cartilage tissue due to its molecular structure and calcium-phosphorus ratio, which are very similar to the inorganic components of normal bone and have excellent biological activity and osteoinductivity. In the implantation of bone defect, there is no fibrous tissue interface ...

It is hypothesised that the use of naturally–sourced raw materials for the synthesis of hydroxyapatite (HA), as a component of a hard tissue constructs, enables enhanced bone remodelling due to the biomimetic physical–chemical characteristics of the HA. The aim of this study was to convert coccolith rich chalk to HA with the potential application of aiding bone ...
Firm and immediate fixation between pedicle screws and bone prevents aseptic loosening and implant failure. Coating with hydroxyapatite is a possible method to improve the fixation of metallic implants in bone. In this study, scanning transmission electron microscopy (STEM) has been used to investigate the ultrastructure of the plasma–sprayed hydroxyapatite ...
This study investigated methyl methacrylate – polymethyl methacrylate powder bed interactions through droplet analyses, using model fluids and commercially available bone cement. The effects of storage temperature of liquid monomer and powder packing configuration on drop penetration time were investigated. ...
