Comparison of Conventional,3D Printed and Novel Hybrid Stabilization Splints in the Management of Temporomandibular Joint Disorders

Overview

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.

Temporomandibular disorders (TMDs) are a diverse group of musculoskeletal and neuromuscular conditions affecting the temporomandibular joint (TMJ), masticatory muscles, and associated structures, leading to pain, functional limitations, and impaired quality of life.5 They encompass more than 30 different conditions that may involve the TMJ, the surrounding masticatory muscles (such as the masseter, temporalis, and pterygoid muscles), or a combination of both.Occlusal splints have long been a cornerstone of TMD management due to their reversibility, simplicity, and efficacy in redistributing occlusal forces, reducing bruxism, and promoting neuromuscular adaptation.16 Understanding their diverse presentation, underlying risk factors, and biopsychosocial context is essential for effective assessment, diagnosis, and management.
