The effect of Staphylococcus epidermidis on the pH and dissolution of substitute bone graft materials
… 11047 on the pH and dissolution of 5 different bone substitute materials. Part 1 – Measured the pH, calcium and phosphate of the culture medium in the presence and absence of the 5 bone substitute materials before and after autoclaving. Part 2 – Measured the pH of the culture medium in the …

In-vitro-Biokompatibilitätstestung modifizierter Apatit- und Oxidkeramiken in der humanen Osteoblastenzellkultur
Presently available bone substitute materials are either bioactive with poor biomechanical stability or they show good biomechanical impact, but are bioinert. The aim of this study was to combine bioactivity of hydroxyapatite (HA) and the mechanical properties of bioinert ceramics like yttrium …

Composite materials made of chitosan and nanosized apatite : preparation and physicochemical characterization
Taking inspiration from nature, where composite materials made of a polymer matrix and inorganic fillers are often found, e.g. bone, shell of crustaceans, shell of eggs, etc., the feasibility on making composite materials containing chitosan and nanosized hydroxyapatite were investigated. A new …

Preclinical Evaluation of 3D Printed Biomaterials for Repairing Critical-Size Bone Defects
… of patients each year suffer from non-healing bone defects secondary to trauma, cancer, osteomyelitis, or congenital anomalies. The standard of care for managing these cases necessitates bone reconstruction surgery. Although using autologous bone (autograft) or banked cadaveric bone (allograft) …

Electron microscopic investigation of interfaces in materials for orthopedic applications
… of the prosthetic joint to the patient's bone, and second, the low generation of wear particles as the components of the prosthesis articulate against each other. This thesis is a study of both of these factors. First, the mechanism of bone apposition to hydroxyapatite (HA) coatings on …

Effect of Calcium Phosphate Ceramic Architectural Features on the Self-Assembly of Microvessels In Vitro
… greatest obstacles to clinical translation of bone tissue engineering is the inability to effectively and efficiently vascularise scaffolds. This limits the size of defects that can be repaired, as blood perfusion is necessary to provide nutrient and waste exchange to tissue at the core of …
