Treatment Outcomes of Temporomandibular Disorders Using Stabilization Splint Supported by the T-scan System.

Abstract

This study aims to evaluate the treatment outcomes of temporomandibular disorders (TMD) using stabilization splints (SS) supported by the T-scan system at Hanoi Medical University Hospital.A clinical, non-controlled intervention study was conducted from May 2023 to October 2024. A total of 36 patients (7 male, 29 female) diagnosed with TMD according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) were included. All patients received treatment with stabilization splints, and the T-scan system (Tekscan, Norwood, MA, USA) was employed to assist in adjusting occlusal contacts and force distribution of the SS. Clinical outcomes, including pain scores (visual analog scale, VAS), mouth opening range (maximum comfortable opening, MCO), occlusal time (OT), and disocclusion time (DT), were recorded and compared at 1 and 3 months.Significant improvements in pain reduction and mouth opening were observed at both 1 and 3 months of treatment. The T-scan data showed a reduction in both OT and DT after 1 month.The use of stabilization splints supported by the T-scan system appears to be an effective treatment for TMD, significantly reducing pain and improving mouth opening range (MCO). Although the T-scan system provides valuable insights into occlusal contacts and force distribution, further controlled studies are needed to fully assess its role in optimizing occlusal adjustments during SS treatment.
