Chitosan is a natural polysaccharide with excellent biocompatibility, biodegradability, and antibacterial capabilities, making it a good candidate for tissue engineering. 3D printing has revolutionized biomaterial fabrication owing to its precision, customization, and ability to create complex structures. This article aims to provide an overview of the current advances in 3D printing techniques for fabricating scaffolds based on chitosan and its derivatives. It also describes various printing methods, including extrusion bioprinting technique, inkjet bioprinting, stereolithography, digital light processing, and indirect 3D printing for controlling porosity, mechanical strength, and biological characteristics of chitosan scaffolds for a variety of tissues, like bone, vascular, cardiac, cartilage, and skin. This review also examines the biological properties of 3D-printed chitosan scaffolds. The advancements in biological performance and 3D printing technology indicate a promising future for developing flexible, customized scaffolds consisting of chitosan.

Chitosan and collagen are natural polymers widely used in biomaterials science; however, their inherent low stability and solubility present several challenges to obtain formulations suitable for potential clinical applications. In this study, tannic acid (TA) was employed as a cross-linker to improve the properties of thin films made from chitosan and collagen. In addition, potassium silicate (PS) was added as an inorganic filler, to produce innovative biocomposite films.

Objective: Regenerative periodontal surgical approaches require scaffolds in a form that can fill narrow and irregular defects. Each scaffold must be specially designed to conform to the shape of the specific defect. The aim of this study was to fabricate nanohydroxyapatite chitosan-gelatin (nHA/KG) pastes with different composition percentages and to analyze the differences in physical, chemical, and biological characteristics in response to periodontal tissue regeneration .

(CTS--GMA)-X was synthesized by two methods to obtain a hydrogel: an aqueous acid media followed by neutralization and a neutral aqueous media, with an extended reaction time. Human epidermal keratinocytes (HEK) and nerve cells (neuroblastoma × glioma hybrid cell NG108-15) were sown over the hydrogels, and their vitality was determined using a calcein stain.
