INNOVATIVE BENEFITS OF A 4D VIRTUAL SIMULATOR

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.
