Application of Two Types of Digital Anterior Repositioning Splints in Temporomandibular Joint Disorders

doi:10.13701/j.cnki.kqyxyj.2025.11.006

Abstract

Abstract: Objective: To compare the application of full-digital workflow anterior repositioning splints and semi-digital workflow anterior repositioning splints in the treatment of temporomandibular joint disorders. Methods: The jaw position of the digital anterior repositioning splint was obtained using intraoral methods and software methods. The study compared the design time of the jaw position, the clinical chairside adjustment time, the improvement of clinical symptoms of the temporomandibular joint before and after treatment, and patient satisfaction between the two groups to explore the clinical application value of the two methods. Results: There were statistically significant differences in the time taken to obtain the jaw position and the clinical chairside adjustment time between the two methods. However, no statistically significant differences were found in the treatment outcomes and patient satisfaction. Conclusion: Both full-digital and semi-digital anterior repositioning splints are suitable for the treatment of temporomandibular joint disorders, and each has its own advantages and disadvantages. The choice should be based on specific circumstances.
