3D Printing of Octacalcium Phosphate Bone Substitutes
Biocompatible calcium phosphate ceramic grafts are able of supporting new bone formation in appropriate environment. The major limitation of these materials usage for medical implants is the absence of accessible methods for their patient-specific fabrication. 3D printing methodology is an excellent approach to overcome the limitation supporting effective and fast fabrication of individual comp...
متن کاملPreparation and In Vitro Biological Evaluation of Octacalcium Phosphate/Bioactive Glass-Chitosan/ Alginate Composite Membranes Potential for Bone Guided Regeneration.
The chitosan/alginate-trace element-codoped octacalcium phosphate/nano-sized bioactive glass (CS/ALG-teOCP/nBG) composite membranes were prepared by a layer-by-layer coating method for the functional requirement of guided bone regeneration (GBR). The morphology, mechanical properties and moisture content of the membranes was studied by scanning electron microscopy (SEM) observation, mechanical ...
متن کاملOctacalcium phosphate as a precursor in biomineral formation.
What are biominerals and how are they formed? It is usually assumed: (i) that the prototype for most apatitic biominerals is hydroxyapatite (OHAp), Ca5(PO4)3OH; and (ii) that the OHAp structure has been modified by the presence of impurity ions and vacancy defects in specific OHAp lattice sites. The usual answer, at least implicitly, to the second question is that the apatitic mineral is formed...
متن کاملHistomorphometric Analysis of Newly-formed Bone Using Octacalcium Phosphate and Bone Matrix Gelatin in Rat Tibial Defects
Background: Repair of bone defects is challenging for reconstructive and orthopedic surgeons. In this study, we aimedto histomorphometrically assess new bone formation in tibial bone defects filled with octacalcium phosphate (OCP),bone matrix gelatin (BMG), and a combination of both.Methods: A total of 96 male Sprague Dawley rats aged 6-8 weeks weighing 120-150 g were randomly allocatedinto thr...
متن کاملAn Octacalcium Phosphate Forming Cement
The osteoconductive and possibly osteoinductive characteristics of OCP increased the interest in preparation of bone graft materials that contain OCP in its composition. Calcium phosphate cements (CPCs) were prepared using a mixture of α-tricalcium phosphate (α-TCP) and dicalcium phosphate anhydrous (DCPA), with α-TCP / DCPA molar ratio of 1/1 and distilled water or 0.5 mol / L phosphate aqueou...
