Introduction: The signs and symptoms of Temporo-Mandibular-Joint (TMJ) dysfunction may accompany cases of class II open bite more frequently than the general population. As this skeletal morphology can increase in risk factors that can compromise TMJ function, orthodontic correction should be carried out with particular care. Mandibular tracking and surface electromyography (sEMG) are important for diagnostics and follow-up.

Aim:To apply the principals of neuromuscular dentistry to orthodontics in class II skeletal open-bite patients.

Methods: This study’s diagnostic and follow-up procedure is based on the use of mandibular tracking (MKG: mandibular kinesiography, or CMS: craniomandibular scanning), surface electromyography (sEMG), and transcutaneous electrical serve stimulation (TENS), according to neuromuscular dentistry principles.

Results: Overjet was reduced, and TMJ signs and symptoms were resolved. Overjet and dental open bite were corrected. The occlusal plane rotated anticlockwise.
