[Personalized design and clinical application of digital occlusal splints based on virtual dental patients]

With the innovation of digital technologies, the personalized fabrication of occlusal splints has shifted from traditional manual methods to an efficient and precise digital workflow. This paper systematically reviews the latest advancements in materials, design technologies, and clinical applications of digital occlusal splints, analyzes core issues in current clinical practice such as insufficient standardization and lack of long-term efficacy evidence, and proposes a dynamic diagnosis-and-treatment protocol based on four-dimensional virtual dental patient technology. Combined with the team's developed functional anterior repositioning splint system and clinical cases, the innovative advantages in treating anterior disc displacement with reduction of the temporomandibular joint are highlighted: achieving precise jaw position regulation, functional restoration, and serialized treatment through multimodal data fusion. Finally, the paper envisions the optimization direction of full-process integration driven by artificial intelligence and new materials, providing theoretical support for the clinical translation of digital occlusal splints.
