A New Approach for Orbital Wall Reconstruction in a Rabbit Animal Model Using a Hybrid Hydroxyapatite-Collagen-Based Implant
Reconstructing the orbit following complex craniofacial fractures presents significant challenges. Throughout the years, several materials have been used for orbital reconstruction, taking into account factors such as their durability, compatibility with living tissue, cost efficiency, safety, and capacity to be adjusted during surgery. Nevertheless, a consensus has not yet been reached on the optimal material for orbital restoration. This study investigates the potential of a hybrid hydroxyapatite-collagen (HAp-COL) material 3D-printed on Ti mesh to be used as an implant for orbital wall reconstruction. HAp-COL powder was synthesized using a high-pressure hydrothermal technique. The powder was further used to 3D-print HAp-COL…
Fabrication and Characterization of 3D-Printed Porous Structures Based on Walstromite-Type Silicate Ceramics
This study investigates the additive manufacturing of 3D porous scaffolds based on walstromite-type silicate ceramics for bone tissue engineering applications. Walstromite powders were synthesized using the sol-gel method and printed using extrusion-based 3D printing. Both sintered and unsintered scaffolds were characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS) analyses to evaluate the effects of sintering on microstructure, porosity, and mechanical properties. Results indicate that the unsintered scaffolds exhibited significantly higher compressive strength due to the presence of organic binders, whereas the sintered scaffolds demonstrated enhanced porosity, facilitating cell…
Prediction Of Mechanical Performance Of 3d Printed CaMgSi2O6 Architectures
In bone tissue engineering, 3D printing technology represents a promising means to obtain complex architectures with the possibility to control precisely the pore size.Diopside (CaMgSi2O6) is a biomaterial which has the ability to induce in vitro apatite formation and in vivo growth and differentiation of the osteoblast. CaMgSi2O6 is a biocompatible material that possesses good bending strength and fracture toughness, bioactivity and slow degradation rate. Due to its outstanding properties diopside has tremendous potential in medical applications.
