Intervention type: COMBINATION_PRODUCT
Group type: ACTIVE_COMPARATOR
Intervention: Transcutaneus electrostimulation therapies
Description: Sterile steel acupuncture needles of 0.25x13mm, disposable AcuBEST brand, and portable electro-stimulator equipment KWD- will be used. The superficial area of the skin of the masseter muscle will be cleaned with alcohol.~Two needles will be placed in each masseter muscle, the area to be punctured is the origin of the masseter muscle or superficial area of the mandibular condyle anterior to the atrial tragus approximately 1cm away, insertion of the masseter muscle at the angle of the mandible. The two double alligator cables will be connected to the head of the needles. The positive pole will be connected at the origin of the masseter muscle and the negative pole at the insertion.~The parameters to be used will be are two frequency bands (210Hz-10140Hz.); amplitude 3050 volts, pulse duration: 40100 msec; and the output intensity: 0.70 (for 100Hz). The treatment time will be 20 minutes.

Intervention: Percutaneus electrostimulation therapies
Description: Kendall® MediTrace 100 conductive adhesive ECG electrodes (pediatric) 2.4 cm in diameter, and portable KWD-808 electrostimulator equipment will be used.~The superficial area of the skin will be cleaned, two electrodes will be placed on each muscle (superficial area of the mandibular condyle and at the angle of the jaw). The current leads will then be connected to the KWD-808 electroacupuncturist to the patient.~Current will be transmitted with a square waveform, 210Hz-10140Hz of frequency, 3050 volts of amplitude and 40100 msec pulse time. The treatment time will be 20 minutes.

Intervention: Oclusal splint
Description: The occlusal splint is worn 24 hours a day, removed for eating and brushing teeth. It is washed with neutral liquid hand soap.~For the preparation, an impression of the maxillary dental arches will be taken with alginate; It is made with acetate .060 and .080.~Relining is done with self-curing acrylic on the occlusal surface of the splint
