Description

Temporomandibular disorders (TMD) encompass all temporomandibular muscular and osteoarticular conditions. TMD affects 31% of the adult population, with chronic, debilitating pain in 10% of cases. Clinical diagnosis remains complex, and patients are underdiagnosed, whereas early management of these disorders can prevent worsening and significant public health expenditure. The Modjaw device, which is integrated into modern digital workflows in dental surgery-particularly for the manufacture of prostheses-could enable systematic joint diagnosis through the automatic interpretation of tracings. The validity of interpreting condylar tracings obtained via axiography (compared to MRI, considered the gold standard) for diagnosing disc displacement in the TMJ has been demonstrated. The team recently demonstrated the reproducibility of Modjaw® condylar recordings from healthy patients, as well as the reliability of the recordings. However, to date, the evaluation of this device has not focused on its added potential in terms of assisting the clinician in diagnosing disc displacement.

Interventions

  • digital jaw impressions and Modjaw® records (Other)
    * digital impressions (optical scanner available in the department); * Modjaw® recording (system available in the department) by an investigator who is unaware of the MRI results; * entry of MRI and Modjaw® data

Eligibility criteria

Inclusion Criteria: * adults; * positive result on the validated questionnaire for the screening of disc displacement; * referral for an MRI scan of the TMJs for diagnostic confirmation * signed informed consent form * membership of a social security scheme Exclusion Criteria: * Patients who do not speak or understand French; * Pregnant women; * Patients who have refused an MRI scan or for whom an MRI scan is contraindicated. * Vulnerable patients, minors, patients under guardianship or trusteeship, or those protected by law.
