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.

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.
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.

RECRUITINGChange in Muscle activity
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
Time frame: Baseline and 3 months
Change in mouth opening
Measure the distance (in mm) between the incisal edge of the maxillary and mandibular central incisors
Time frame: Baseline and 3 months
Change in pain
NRS will be measured from the patient mark from 0 to 10, where 0 representing no pain and 10 representing the worst pain.
Time frame: Baseline and 3 months
