RHEOLOGICAL CHARACTERISATION OF DIFFERENT ALGINATE-BASED HYDROGELS FOR A BIOMIMETIC REPRESENTATION OF A TOOTH

Abstract Introduction In bioprinting, it is essential to correctly characterise the materials be used in order ensure highest cell viability while maintaining best structural properties of hydrogels. Methods Alginate-based hydrogels with different concentrations have been characterised because they are currently ones printing according literature. The chosen were 3.5%, 4% and 5% alginate, then a scaffold was bioprinted one mechanical properties. Finally, 3D model tooth check integrity hydrogel as somewhat more complex structure than simple scaffold. Results It could observed that, despite suffering similar viscosity loss rest, sample when subjected shear stresses containing alginate concentration. When bioprinted, that result positive, visual analysis corresponded parameters programmed design software. Likewise, subsequent bioprinting dental showed good results. Conclusions by rheometry behaviour respect viscosity. Furthermore, found higher allowed for quality bioprints.
