Study of Temporomandibular Joint Dysfunction

Completed

• Conditions: Diseases of the Temporomandibular Joint
• Interventions: Other: Measurement of natural electrical activity of facial muscles; Other: Measurements of jaw movement

• Registration Number: NCT03305315
• Lead Sponsor: Centre Hospitalier Universitaire Dijon

Brief Summary

Given the frequency of temporomandibular joint (TMJ) dysfunction and the variations in its expression, this project intends to initiate a process of objective evaluation of mandible function and its impairment due to different diseases. The first step is to determine whether 3D kinematic quantification of the mandible would make it possible to objectively assess the effect of post-operative management on TMJ function recovery. If the first results are encouraging and show the sensitivity of the analysis of minor joint dysfunctions, the investigators will evaluate the feasibility of kinematic assessments for major TMJ dysfunctions and for the follow-up of patients.

The expected benefits of this study are to be considered in the medium term and concern the possibilities offered by measuring mandible kinetics in the treatment of TMJ disorders.

Inclusion Criteria

Patients:

• Patients who have provided verbal consent,

• Absence of headache,
• Absence of tinnitus,
• Kinematic curves around the mean.

Exclusion Criteria

• Adults under guardianship,
• Patients without national health insurance cover.
