This prospective, multi-center, open-label, single-arm clinical study will evaluate the efficacy and performance of the BTL-043 and BTL-785F devices for alleviating TMJ pain. Up to 60 subjects will undergo four treatment visits, administered 2-10 days apart, followed by 1-month and 3-month follow-up visits. During a single treatment session at each visit, subjects will receive consecutive treatment with both devices. At baseline, informed consent, eligibility assessment, Fitzpatrick phototype evaluation, TMD Disability Index, VAS, weight and height measurements, 2D mandibular ROM photographs, and mandibular/lateral ROM assessments will be completed. A urine pregnancy test will be performed prior to each treatment visit. After the final treatment, subjects will complete the TCQ, SSQ \& QoL, TMD Disability Index, and VAS, and repeat all physical assessments. At both follow-up visits, subjects will complete the SSQ \& QoL, TMD Disability Index, and VAS, and repeat the physical assessments. Safety will be evaluated through documentation and assessment of adverse events at each treatment and follow-up visit.

Change from Baseline in the Temporomandibular Dysfunction (TMD) Disability Index Score at 3 Months
The Temporomandibular Dysfunction (TMD) Disability Index is a self-reported questionnaire used to assess the impact of TMJ disorders on a participant's daily activities, such as talking, chewing, and sleeping. The questionnaire consists of 10 categories, each containing 5 statements. Each category is scored on a scale from 0 to 4, where 0 represents no limitation and 4 represents maximum restriction due to pain. The overall score is calculated by summing the scores of all 10 items, resulting in a total possible score ranging from 0 to 40. On this scale, a total score of 0 indicates no disability and 40 indicates extreme disability. A negative change from baseline (a decrease in the total score) indicates a reduction in disability and an improvement in the participant's condition over time.
Time frame: Baseline and 3 months
Change from Baseline in the Visual Analogue Scale (VAS) Pain Score at 3 Months
The Visual Analogue Scale (VAS) is a self-reported measure used to assess the intensity of TMJ-related pain experienced by the participants in the treatment area. Participants rate their perceived pain level on a numerical scale ranging from 0 to 10. On this scale, 0 is equivalent to "no pain" and 10 indicates the "worst possible pain". The baseline score is compared to the score collected at the 3-month follow-up visit. A negative change from baseline (a decrease in the VAS score) indicates a reduction in pain intensity and an improvement in the participant's condition over time.
Time frame: Baseline and 3 months
Change from Baseline in Mandibular Range of Motion at 3 Months
Mandibular range of motion is measured objectively in millimeters (mm) using a specialized scale. Two measurements are taken: "comfort" (opening the mouth to a comfortable level without pain) and "active" (opening the mouth as wide as possible despite the presence of pain). A positive change from baseline (an increase in the measured mm) indicates an improvement in jaw mobility.
Time frame: Baseline and 3 months
Change from Baseline in Lateral Range of Motion at 3 Months
Lateral mandibular range of motion is measured objectively in millimeters (mm) using a specialized scale. Two measurements are taken: left lateral excursion (moving the lower jaw as far as possible to the left) and right lateral excursion (moving the lower jaw as far as possible to the right). A positive change from baseline (an increase in the measured mm) indicates an improvement in lateral jaw mobility.
Time frame: Baseline and 3 months
Subject Satisfaction Assessed by the Subject Satisfaction & Quality of Life Questionnaire
Subject satisfaction with the treatment outcomes and its impact on quality of life is assessed using a 17-item self-reported questionnaire. Each item is rated on a 5-point Likert scale, where 1 indicates "strongly disagree" and 5 indicates "strongly agree". Higher scores represent greater treatment satisfaction and improvement in the subject's quality of life.
Time frame: 3 months post treatment
Therapy Comfort Assessed by the Therapy Comfort Questionnaire
Therapy comfort is assessed using a self-reported questionnaire. Participants indicate their overall comfort on a 5-point Likert scale (where 1 is "strongly disagree" and 5 is "strongly agree" with the statement "I found the treatment comfortable"). Additionally, any pain experienced during treatment is rated on a Numerical Analogue Scale ranging from 0 ("no pain") to 10 ("worst possible pain"). Lower pain scores and higher agreement scores indicate greater therapy comfort.
Time frame: Immediately after the final treatment
Incidence of Treatment-related Adverse Events
Overall safety is evaluated continuously by monitoring, assessing, and recording the occurrence and severity of any adverse events, side effects, or unanticipated problems throughout the course of the study
Time frame: From baseline up to 3 months post-treatment
