Abstract
Carbonated-hydroxyapatite (CHA) and Si-hydroxyapatite (Si-HA) precipitation have been synthesized from the model bioliquid solutions (synovial fluid and SBF). It is found that all the samples synthesized from the model solutions are single-phase and represent hydroxyapatite. The crystallization of the modified hydroxyapatite on alloys of different composition, roughness and subjected to different treatment techniques was investigated. Irradiation of the titanium substrates with the deposited biomimetic coating can facilitate further growth of the crystal and regeneration of the surface.
Highlights
Much attention is paid to improving the quality of life and lifespan [1]
To deposit hydroxyapatite on the VT1-0 titanium surface, the titanium plates 15 mm*15 mm*1.2 mm in size were pretreated: polished; etched; exposed to power ionization beam; perforated and plates which were not subjected to mechanical impact and chemical attack
The results obtained by X-ray diffraction analysis (XDA) indicate that throughout the range of varied carbonate ion concentration, the produced hydroxyapatites are of low crystallinity, for which the lattice parameters are evaluated [14]
Summary
Much attention is paid to improving the quality of life and lifespan [1]. In medical practice, to save lives and restore important physiological functions of patients we have to resort to reconstruction of bone and tooth tissue through replacing the defect with an implant [2]. Modern trends in the development of high technologies and laboratory base of research centers require advances in the technology of medical products and expansion of their diversification to meet the requirements of international standards and to reduce their prime cost. The solution of this problem is production of a bioactive coating on metal implants [9,10,11,12,13]. The hydroxyapatite coating on the implant surface ensures rapid and effective engraftment in the bone structure due to high level of biological activity of the surface
