METHOD OF REGISTRATION OF CLICKING NOISE IN TEMPORO-MANDIBULAR JOINT IN PATIENTS WITH TEMPORO-MANDIBULAR JOINT DYSFUNCTION CAUSED BY MASSETER MUSCLE HYPERTENTION Russian patent published in 2009 - IPC A61C19/04 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to orthopedic dentistry, and can be applied for registration of clicking noise in temporo-mandibular joint (TMJ) in patients with TMJ dysfunction, caused by masseter muscle dysfunction, in order to diagnose pathology and evaluate conducted therapy efficiency. Axiography with displacement of lower jaw in vertical plane is performed and clicking noise corresponding to reposition or dislocation of articular disc is registered by deviation of trajectories of opening or closing of mouth on axiogram from the norm. In case if trajectories of opening or closing of mouth deviate from norm on axiogram sections corresponding to starting phase of mouth opening and final phase of mouth closing, first clicking noise is diagnosed, corresponding to reposition of articular disc in starting phase of mouth opening, and second clicking noise, corresponding to dislocation of articular disc in final phase of mouth closing. In case if trajectories of opening or closing of mouth deviate from norm on axiogram sections corresponding to middle or final phase of mouth opening and middle or starting phase of mouth closing, first clicking noise corresponding to dislocation of articular disc in middle or final phase of mouth opening, and second clicking noise corresponding to reposition of articular disc in middle or starting phase of mouth closing.

EFFECT: method allows to detect changes of masticatory apparatus at early stages of disease, determine position of joint elements, elaborate individual for each patient treatment policy and to control its results.
