β-Tricalcium phosphate shaped by replica method

Fabrication of Poly(ε-Caprolactone), Hydrophilic and β-Tricalcium Phosphate Layer- by -Layer Nanofibrous Scaffolds for Tissue Engineering

In this study, using biodegradable polymers, nanofiberouse scaffolds were fabricated from the layer-by-layer electrospinning method, including two layer that poly (ε-caprolactone), polyvinylpyrrolidone deposited at first layer and poly (ε-caprolactone), polyvinyl alcohol , β-tricalcium phosphate at latter. After prepration of scaffolds, scanning electron microscopy (SEM), swelling, porosity, me...

Hydrogen-substituted β-tricalcium phosphate synthesized in organic media

β-Tricalcium phosphate (β-TCP) platelets synthesized in ethylene glycol offer interesting geometries for nano-structured composite bone substitutes but were never crystallographically analyzed. In this study, powder X-ray diffraction and Rietveld refinement revealed a discrepancy between the platelet structure and the known β-TCP crystal model. In contrast, a model featuring partial H for Ca su...

Chemical stability of grain boundaries in β-tricalcium phosphate ceramics

3D Powder Printed Bioglass and β-Tricalcium Phosphate Bone Scaffolds

The use of both bioglass (BG) and β tricalcium phosphate (β-TCP) for bone replacement applications has been studied extensively due to the materials' high biocompatibility and ability to resorb when implanted in the body. 3D printing has been explored as a fast and versatile technique for the fabrication of porous bone scaffolds. This project investigates the effects of using different combinat...

Implantation of Tetrapod-Shaped Granular Artificial Bones or β-Tricalcium Phosphate Granules in a Canine Large Bone-Defect Model

We investigated biodegradability and new bone formation after implantation of tetrapod-shaped granular artificial bone (Tetrabone®) or β-tricalcium phosphate granules (β-TCP) in experimental critical-size defects in dogs, which were created through medial and lateral femoral condyles. The defect was packed with Tetrabone® (Tetrabone group) or β-TCP (β-TCP group) or received no implant (control ...
