Endoprosthetic dental implants

The number of patients receiving biomedical endoprosthetic, dental and other implants to correct skeletal defects and heal diseases are constantly on the rise worldwide. A rough estimate of metallic, ceramic and polymeric implants of all kinds delivered worldwide to patients are in the range of 10 million annually. Consequently, the number of orthopaedic surgeries worldwide is growing by 10-12% per year (Tomsia et al., 2005). 

Gas detonation spraying of hydroxyapatite yielded thick coatings with remarkable properties (Klyui et al., 2011). The coating thickness reached during only 20 s of spraying was 280 pm. Adhesion strength to a titanium substrate was up to 80 MPa, and no decomposition phases were observed by XRD. The stems of hip endoprosthetic implants and acetabular cups as well as dental implants...
