Characterization of bioceramics coating and evaluation of the influence of kind of coating on the implantation has been developed in recent years.Different bioceramics coating like calcium phosphate, hydroxyapatite, fluorapatite and bioglass were coated on dental and orthopedic implants. In-vitro and in-vivo experiments were done for evolution of implant success and reliability and study of fac...
Different methods for the functionalization of carbonate hydroxyapatite granules with free amine groups by reaction with (3-aminopropyl)triethoxysilane (APTES) have been compared in order to improve the potential for tethering of bioactive molecules to bioceramics. The combined use of tetraethoxyorthosilicate and APTES with acid catalysis resulted in an evident increase in amine surface grafting.
Magnesium whitlockite (Mg-WH, Ca18Mg2(HPO4)2(PO4)12) is a promising candidate for biomedical application in bone regeneration; however, the fabrication of Mg-WH bioceramics by conventional methods limited. known to be...
The field of biomedical engineering relies heavily on materials known as bioceramics due to their many advantages. That’s also because are often used in the tissue well implant applications. It is a direct consequence effective use bioceramics. Three-dimensional printing now production technology most for On other hand, there various approaches (3D Printers). manufacturing processes have certai...
In this paper we present a synthesis method of calcium phosphate bioceramics such as hydroxiapatite, the mineral component of bones and hard tissue in mammals. Investigations carried out have confirmed obtaining of hydroxyapatite characterized by a high degree of crystallinity, purity, and a good stoichiometry.
Calcium phosphate bioceramics are widely used in orthopedic and dental applications and porous scaffolds made of them are serious candidates in the field of bone tissue engineering. They have superior properties for the stimulation of bone formation and bone bonding, both related to the specific interactions of their surface with the extracellular fluids and cells, ie, ionic exchanges, superfic...
