Intervention model description: A single-group, non-randomized clinical study where all enrolled participants received stabilization splint therapy supported by T-scan system-assisted occlusal adjustment. No control or comparison group was used.
Primary purpose: TREATMENT

Brief summary: 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. Thirty-six patients diagnosed with TMD based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) received customized stabilization splints. The T-scan system was used to optimize occlusal adjustments by providing real-time digital recordings of occlusal force distribution. Clinical outcomes, including pain intensity (measured by Visual Analog Scale - VAS), maximum comfortable mouth opening (MCO), occlusal time (OT), and disocclusion time (DT), were assessed at baseline, 1 month, and 3 months after treatment. The study investigates the effectiveness of T-scan-assisted occlusal adjustments in improving clinical symptoms and enhancing jaw function in patients with TMD.

Detailed description: This clinical study evaluates the therapeutic effectiveness of stabilization splints (SS) supported by digital occlusal analysis using the T-scan system in patients with temporomandibular disorders (TMD). Thirty-six participants diagnosed with TMD according to the DC/TMD criteria were enrolled and treated at Hanoi Medical University Hospital. Custom-fabricated Michigan-type stabilization splints were provided to all participants. Occlusal adjustments were initially performed using articulating paper and then refined with the T-scan system, which measures occlusal timing and force distribution in real-time.

The primary focus was on improving clinical symptoms such as pain reduction and jaw mobility enhancement. Pain intensity was assessed with the Visual Analog Scale (VAS), and maximum comfortable mouth opening (MCO) was recorded. Occlusal Time (OT) and Disocclusion Time (DT) were evaluated using the T-scan system. Patients were followed up at 1 and 3 months post-treatment to monitor changes.

The study explores the supportive role of digital occlusal adjustment in the conservative management of TMD and highlights the potential of the T-scan system to enhance the precision of splint therapy without direct modification of the natural dentition.
