Advances in 3D printing for dentistry: clinical applications and future perspectives

The advent of three-dimensional (3D) printing has transformed modern dentistry by introducing innovative approaches that enhance customization, precision, and efficiency in clinical and educational settings. This review provides a comprehensive analysis of recent developments and emerging trends in 3D printing applications within dentistry. It explores key domains, including Applications in Orthodontics, Applications in Crown Production, Applications in Implants and Surgical Guides, 3D Printing Applications in Dentures, and Applications in Dental Models and Educational Tools. In orthodontics, 3D printing facilitates the production of patient-specific aligners, brackets, and retainers, improving treatment accuracy and reducing turnaround times. In crown production, the integration of computer-aided design and manufacturing (CAD/CAM) with additive manufacturing allows for the fabrication of highly precise and esthetic prosthetic crowns with rapid chairside delivery. One of the most impactful uses is seen in implants and surgical guides, where 3D printing supports the creation of customized surgical templates and implant components, thus enhancing procedural outcomes and reducing surgical risks. 3D printing has revolutionized denture fabrication by enabling the production of complete and partial dentures with improved fit, material efficiency, and reduced laboratory time. In dental education, the technology is increasingly employed to produce anatomical models, simulated teeth, and other educational tools that improve student training and diagnostic planning. The novelty of this review lies in its integrative perspective linking technical advancements with practical dental applications and highlighting material innovations such as nanocomposites and biocompatible polymers. It also discussed future prospects such as AI-driven design optimization and the role of smart materials in expanding clinical applicability. By presenting a structured overview across multiple specialties, this paper offers valuable insights into how 3D printing is reshaping the future of dental care and education.
