myograph Synapsis Dental

Synapsis for stomatological examinations is a four-channel adaptive electromyograph (myograph) and a special computer complex for the examination of the electrobiological activity of face muscles and nerves, electromyogram. It's intended for registration, processing, analyzing and graphic representation of the electromyograms and event-related responses of masticatory and mimic muscles.

Purpose

Synapsis for stomatological examinations is a four-channel adaptive electromyograph that allows evaluating the reciprocal regulation and functional relations of symmetrical antagonist, agonist and synergist muscles during the process of chewing or moving the lower jaw bone. The complex allows controlling the overall efficiency of the treatment and correct applied methods and procedures.

Synapsis Electromyograph can be used in the field of Stomatology and dentistry in the following situations:

craniofacial abnormalities and traumas
craniofacial inflammation
dental implants
native and acquired dentofacial deformations
temporomandibular joint diseases
denture defects
excessive attrition of teeth
periodontal diseases
the anomaly of occlusion
dental restorations
paresis or paralysis of the facial nerve
polyneuropathy
overall treatment efficiency control

Software features

Database to store information about the patients and examinations
Software complex to control all the parameters of the monitored signals and stimulating actions.
Automatic and automated detection of the required segments of the electromyogram.
Digital signal processing algorithms for classification, calculation, and graphic representation.
Ability to create reports.
