“…Alternatively, the hydrogel may be applied as degradable scaffold or mold in 3D printing, because of its proven extrudability and controllable degradability. 46 For example, the coacervate gel could be printed as a mold or scaffold to support the printing of a second material, after which the mold or scaffold can be easily removed by immersing it in an amine–rich medium. Overall, we conclude that this chemical-signal-regulated coacervate hydrogel could be used as injectable material (preferably with DVP as the activator for obtaining a more biocompatible material) or as scaffold in 3D printing.…”

“…Inkjet printing is the first bioprinting technology with a cartridge that stores bio-ink. This method is generally known for its affordability and easy accessibility, as commercial printers can be easily modified to accommodate the technology [ 13 , 14 , 15 , 16 ]. It has also demonstrated high cell viability; approximately 80–90% of cells remain functional [ 16 ].…”

In the past decade, immense progress has been made in advancing personalized medicine to effectively address patient-specific disease complexities in order to develop individualized treatment strategies. In particular, the emergence of 3D bioprinting for in vitro models of tissue and organ engineering presents novel opportunities to improve personalized medicine. However, the existing bioprinted constructs are not yet able to fulfill the ultimate goal: an anatomically realistic organ with mature biological functions. Current bioprinting approaches have technical challenges in terms of precise cell deposition, effective differentiation, proper vascularization, and innervation. This review introduces the principles and realizations of bioprinting with a strong focus on the predominant techniques, including extrusion printing and digital light processing (DLP). We further discussed the applications of bioprinted constructs, including the engraftment of stem cells as personalized implants for regenerative medicine and in vitro high-throughput drug development models for drug discovery. While no one-size-fits-all approach to bioprinting has emerged, the rapid progress and promising results of preliminary studies have demonstrated that bioprinting could serve as an empowering technology to resolve critical challenges in personalized medicine.

“…Vigorous development of medical additive manufacturing technology, breakthrough medical grade titanium powder and nickel-titanium alloy powder and other key raw material constraints, can be a new idea in the manufacture of root canal files. Three-dimensional (3D) printing technology [ 153 ] is driving changes in the medical and health care industry, and titanium and titanium alloys [ 154 ], as biomedical materials with excellent performance are developing at an alarming rate. The combination of the two will help push personalized medicine to shine.…”

The goal of this review is to present a detailed and comprehensive description of the published work from the past decade regarding methods of improved material, geometric design, and additional functions in root canal files. The main improved methods of files and the most common technologies were further addressed, underlining their advantages and main limitations. Online databases (the Derwent Innovations Index) were consulted on this topic. Published work from 2010 to 2022 was collected and analyzed the relevant papers were chosen for inclusion in this review. The patent map classified the latest phase of the root canal files based on the analysis of the number of patents. The performance of the root canal files, such as materials. Directly affects the quality of the root canal therapy. We provided a thorough review of advances in the field of root canal files. In particular, three categories of improved methods were examined and compared, including material-based methods, geometry-based methods, and those based on additional functions. To understand this state of the art of different improved methods of root canal files, we conducted a literature analysis and a series of comparisons between different methods. The features and limitations of each method of root canal files were further discussed. Finally, we identified promising research directions in advancing the methods for the improved performance of root canal files. There is no perfect technology for all material/geometric design/additional functions, capable alone of fulfilling all the specificity and necessities of every patient. Although it is very promising, the material of the files remains understudied, and further work is required to make material science a pervasive technology in root canal therapy, and contribute to endodontic and periapical diseases by assisting in the subsequent development of root canal files.
