Process for engineering instant nanoporous bio-artificial bone tissue composite is designed aiming the prevention of body immune reaction when integrated with host bone tissue and also reduces its period of integration. This nanoporous biocomposite is compounded by a number of ingredients. Hydroxylapatite (HA), or/and alpha- or beta-tricalcium phosphate (α- or β-TCP). Polycaprolactone (PCL) or polylactic acid (PLA). Any gelatinable solution or gel, then water is added in relevant quantity for producing gel or injectable solution of this biocomposite. Any substance composed of any connective collagen tissue. Recombinant Human Vascular Endothelial Growth Factor. Any kind of acrylate when the hardening and final process of all this compound is acquired immediately by ultrasound treatment.
