  Abstract: Digital technology is ushering in a new era of precision medicine in orthodontics. Rapid prototyping (RP) technology, as a crucial manufacturing link in the digital workflow, has become a core driving force in revolutionizing orthodontic diagnosis and treatment models due to its high precision, efficiency, and powerful capability for personalized customization. This article systematically reviews the principles, characteristics, and suitability in dentistry of mainstream RP technologies such as stereolithography and selective laser sintering. It focuses on an in-depth analysis of the clinical applications and evidence-based support for this technology across five core scenarios: customized bracket systems, clear aligner fabrication, digital surgical guides for implantation, design of functional occlusal splints, and high-precision teaching models. Literature analysis indicates that this technology can significantly enhance treatment predictability, safety, and patient comfort while fundamentally optimizing clinical workflows. Furthermore, the physical models it generates demonstrate irreplaceable value in doctor-patient communication, clinical teaching, and skills training. Looking ahead, integration with artificial intelligence and novel smart materials holds even greater potential. This article aims to provide clinical dental practitioners,? with an evidence-based practical guide for technology application and to explore its integration pathway within continuing dental education systems.
