Abstract

Three-dimensional (3D) printing, commonly referred to as additive manufacturing, has revolutionized modern dentistry by facilitating the production of highly accurate, patient-specific devices and models. This cutting-edge technology enables the creation of a diverse range of applications, including prosthodontic restorations, orthodontic aligners, implant surgical guides, craniofacial prostheses, and regenerative scaffolds, all with remarkable precision. The integration of 3D printing into digital dentistry workflows has significantly enhanced treatment planning, shortened turnaround times, and improved patient outcomes. The versatility of materials—encompassing resins, polymers, ceramics, and metals—has broadened the scope of 3D printing across various dental specialties. However, despite these advancements, challenges remain, such as high costs, regulatory hurdles, discrepancies in accuracy among different printers, and concerns regarding the long-term durability of materials. Looking ahead, future developments in 3D printing are anticipated to focus on bioprinting functional tissues, incorporating artificial intelligence into design processes, promoting wider accessibility in clinical settings, and advancing biomaterials for regenerative applications. This review provides an in-depth exploration of the current applications of 3D printing in dentistry, while also evaluating emerging innovations that are set to transform the landscape of oral healthcare.
