3D Printing in Endodontics

With increasing demand for precision and personalization in dentistry, we need to metamorphose stereotypical dental treatment and workflow. In this context, 3D printing, also termed “additive manufacturing,” is one such platform that has currently enveloped almost all spheres of oral medicine. Based on the wide range of manual competencies with microscopic resolution required in endodontics, it is highly imperative to establish accurate, reproducible, effective, and patient-clinician-friendly treatment procedures and inventory. 3D printing is a meticulous, cost-effective, and user-friendly solution to these concerns. Today, 3D printing has found a vital role in endodontics, ranging from clinical to education, including innovative research applications. In this chapter, we emphasize the past, present, and future prominence of this technique in the field of endodontics. We will highlight the various technologies of additive manufacturing and their underlying mechanism of action. The functionality of additive manufacturing in improving current trends in endodontics will focus mainly on guided endodontic procedures and surgeries, educational root canal models, and experimental approaches in the research on dental pulp biology and future regenerative approaches.
