This test can document, assess, note, describe, evaluate, and record the presence, location, loudness, timing, consistency, and quality of joint vibrations.
This analysis is important to determine and diagnose temporomandibular disorders. Every joint disease has its own characteristics sounds and vibrations.
Electromyography (EMG) is the science of recording the electrical activity of muscle fibers. It is a diagnostic procedure that assesses the health of muscles and the nerve cells that control them (motor neurons).
The results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission and it records bilateral, simultaneous measurement of the craniomandibular muscles.
This test can measures and record mandibular movement using a jaw tracking sensor array. Three dimensions of movement can be measured: Vertical, Anterior/Posterior, and Lateral translations or movements.
The activity muscle during mastication is given by masticatory muscle (anterior-temporalis and masseter). Jaw movement velocity and trajectory to characterize the chewing behavior were also recorded by Electrognathography (EGN) during mastication.
Significant differences in sensory attributes, muscle activities, and jaw movements among subjects.
The T-Scan system is a valuable tool that aids in the diagnostic process of analyzing a patient’s bite and showing what is and what is not functioning properly. When a bite is unstable it can cause pain, teeth and dental restorations to crack and break, gum disease, tooth loss, headaches, and TMJ Disorder.
Using the T-Scan sensor, we can used to record TA and MM muscle activity during clenching, muscle strength, muscle symmetry or asymmetry, firing time, and bite force.
Most studies show that the maximum jaw range of motion (ROM) or maximum mouth opening (MMO) is related to body size and height. Men can usually open wider than women, taller people more than shorter people. In studies, MMO for adults has generally been around 42 mm.
BioTENS is a compact, Ultra-Low Frequency, Transcutaneous Electrical Neural Stimulator (ULF-TENS). This test (Transcutaneous Electrical Neural Stimulation) delivers a precisely regulated, bilaterally simultaneous, direct and rhythmic stimulus to both the masticatory and the facial muscles by short-duration and small amplitude electric pulses.
