Stabilization Appliance: Participants will receive a maxillary stabilization appliance fabricated from 2-mm hard thermoplastic material using diagnostic casts. The appliance fit will be verified, and patients will be instructed to wear it for 3 months.
Ear Stent: Participants will undergo ENT evaluation prior to ear impression taking. Custom ear stents will be fabricated from soft addition silicone and hollowed to prevent hearing impairment.
Study summary
Temporomandibular disorder (TMD) is a common condition with multifactorial etiology, including trauma, emotional stress, parafunctional habits, and occlusal discrepancies. TMD may be classified as myogenous, involving the masticatory and cervical muscles, or arthrogenous, affecting the temporomandibular joint structures. Management approaches range from noninvasive to invasive methods. The intraoral stabilization appliance (SA) is a widely used noninvasive treatment, while the ear stent (ES) has recently been introduced for managing myogenous TMD.
Aim: This randomized clinical trial aims to compare the effectiveness of SA and ES in the management of myogenous TMD.

Primary outcome measure(s)
Change in Muscle activity — Baseline and 3 months surface electromyography will be used to assess the temporalis and masseter muscles. The electrodes detect the electrical potentials generated by muscle fibers when they contract. This electrical activity is amplified and recorded by an electromyograph machine
Change in mouth opening — Baseline and 3 months Measure the distance (in mm) between the incisal edge of the maxillary and mandibular central incisors
