Brief Summary

Occlusal splint therapy is a well-established conservative approach for the management of temporomandibular disorders (TMDs); however, variability in clinical outcomes suggests that no single splint design is universally optimal. Conventional chairside stabilization splints are widely used and allow immediate intraoral adjustments; however, they are technique-sensitive and may compromise long-term fit and patient comfort. Conversely, 3D-printed occlusal splints provide superior precision, reproducibility, and material stability; however, their uniformly rigid structure may limit initial comfort and patient compliance, particularly in patients with acute pain or muscle tenderness. To address these limitations, the researchers intend to develop an innovative hybrid occlusal splint i.e. Dual material 3D printed stabilization splint, that integrates both hard and soft components. This design aims to combine the biomechanical stability and occlusal precision characteristic of rigid splints with the cushioning effect and enhanced comfort provided by soft splints. The objective is to improve adaptation, compliance, and the sustained therapeutic efficacy of the splint.

Outcome Measures

Primary Outcomes (3)

  • Visual Analog Scale (VAS)

    To evaluate and contrast pain relief by using the Visual Analog Scale (VAS).The scale ranges from 0 to 10 where 0 is the minimum VAS score and 10 is the maximum score. Score of 0 indicates no pain and score of 10 indicates maximum pain intensity.

    Baseline, 1 week, 2 weeks, 4 weeks

  • Maximum Mouth Opening

    To evaluate functional improvement by Measuring the change in Maximum Mouth Opening (MMO) in millimetres from baseline to 1 month.

    Baseline, 1 week, 2 weeks, 4 weeks

  • Maximum Bite Force

    To quantify masticatory efficiency by measuring changes in Maximum Bite Force (MBF) using a bite force analyser device.

    baseline, 1 week, 2 weeks, 4 weeks

Secondary Outcomes (1)

  • Patient Compliance
