EMG for Muscle Function Evaluation

Diagnostic Tests for TMD


EMG is one of biometric tests that occur in the modern evidence-based dentistry practice. It is an advanced technique to record and evaluate muscle activity.

What is EMG?

Electromyography (EMG) is well-defined as the recording and study of the fundamental electrical properties of skeletal muscle using superficial or needle electrodes which basically determine the muscle is contracting or not. EMG is widely practiced both in clinical and research fields.

Uses In Dentistry?

EMG is most commonly used in

  • Temporomandibular joint (TMJ) disorders [TMJ dysfunction, dystonia, muscle disease of head and neck, cranial nerve lesion, and also seizure disorders].
  • Diagnosis of facial muscle during orthodontic treatment related to neuromuscular approach and facial pain associated with the use of functional appliance
  • Noninvasive investigation of the bioelectrical phenomena of muscular contraction.
  • Allows the examination of some important muscles involved in chewing, swallowing, and posture of the head (typically masseter, temporalis anterior and posterior, digastric anterior, sternocleidomastoid)

Where We Use In Our Clinic?

We utilize EMG to evaluate muscular activity in function such as chewing and biting or parafunctional activities such as clenching and bruxism to treat TEMPOROMANDIBULAR DISORDERS.
